Reduce Water Consumption Research Articles

Water usage pattern in the aftermath of COVID-19

Maintenance of good health and avoiding a viral infection is the prime focus for an individual during COVID-19 pandemic. Water being a universal solvent is used widely to clean the disinfectants in public places and individual household level. This study was designed to find any change in the water consumption pattern among the households after the emergence of COVID-19. To study this, a questionnaire was prepared and sent to the respondents through Google Forms. Collected data was analysed using suitable statistical methods and the results indicate that there was a significant change in the consumption pattern of drinking water from cold to hot (37.98%) among the respondents and also with respect to the total water usage. As the disease is communicable in nature, more water is needed to clean and disinfect the surface areas, washing hands etc. This eventually has a significant burden on the water resources in countries where water is already deficient, like India. It is recommended to adopt water conservation practices/technologies at the individual level by means of rain water harvesting techniques or use of efficient water aerator taps etc. to reduce water consumption.

Application of Best Available Techniques to Remove Air and Water Pollutants from Textile Dyeing and Finishing in South Korea

The textile industry in South Korea is characterized by excessive water consumption, high concentrations of wastewater, hazardous chemicals, and high energy consumption. This study aimed to analyze Best Available Techniques Reference Documents (BREFs) based on best available techniques (BATs) and BAT-associated emission levels (BAT-AELs) and identify potential solutions for tackling environmental pressure from the South Korean textile industry. Therefore, the existing practices of the textile dyeing and finishing industry in South Korea were compared with those from the BREFs of the European Union. Many existing BATs in South Korea are related to reducing water consumption. There is also a strong focus on BATs for reducing wastewater discharge and achieving energy-saving during treatment rather than after treatment, which differs from other industries. Moreover, BAT-AELs were derived for chemical oxygen demand, suspended solids, and total nitrogen for treating non-biodegradable, highly polluted wastewater. Furthermore, BREFs related to atmospheric pollution included dust generated from the heated fabrics in the finishing process that contained cadmium and phenolic hydrogen chloride from dyes and raw materials in the fabrics. Notably, the European Union has not specified BAT-AELs for the textile industry, whereas South Korea has tailored BAT-AELs for toxic and hazardous chemicals. Thus, numerous green techniques to reduce emissions and energy consumption are being implemented in South Korea.

Elicit Plant raises funds for biostimulant

Elicit Plant has raised $18.3 million in series A funding to research and commercialize its phytosterol-based biostimulant, which make plants more resistant to drought. Phytosterol is a molecule found naturally in plants that reduces water consumption. The product, which the company says can substantially increase yields, is applied to corn and soybean leaves. The French company will use the funding to develop products for new crops and to expand in Europe, North America, and South America.

Control of water intake by a pathway from the nucleus of the solitary tract to the paraventricular hypothalamic nucleus

Several brain areas have been shown to participate in thirst and control of fluid intake. An understanding of how these circuits interact, and their roles in the activation, maintenance, and termination of fluid intake remains incomplete. Central glucagon-like peptide-1 (GLP-1) receptor activation appears to be an important part of the termination of drinking, but the site(s) of action for this suppression has not yet been determined. In an attempt to use GLP-1 responsiveness as a means to screen targets of hindbrain cells that participate in the termination of thirst and the resultant water intake, we injected the GLP-1 receptor agonist exendin-4 (Ex-4) into three brain areas known to express GLP-1 receptors, and measured subsequent water intake. Ex-4 reduced water consumption when injected into the paraventricular hypothalamic nucleus (PVH) and nucleus of the solitary tract (NTS), but not when injected into the nucleus accumbens (NAc). Using the effective response after injection into the PVH as a guide, we examined the connection between the NTS – the site of endogenous central GLP-1 production – and the PVH. Retrograde tracing combined with Fos immunohistochemistry suggested intake-induced activity in PVH-projecting NTS cells. To test the hypothesis that this pathway is important in the termination of drinking, we chemogenetically activated PVH-projecting hindbrain cells. Interestingly, activation of this population of cells increased water intake, calling into question the heterogeneity of the pathway with respect to the control of fluid intake. Taken together, we conclude that the PVH is a site of action for GLP-1 receptor activation in the inhibition of water intake, but suspect that endogenous GLP-1 in NTS-to-PVH projections may be counterbalanced by a parallel pathway that either activates or maintains already activated water intake.

Economical use of water in cotton knit dyeing industries of Bangladesh

Textile knit dyeing industries of Bangladesh are playing a significant role in the country's economy and retain above forty percent of the total annual export performance. Economical use of water in the knit dyeing industries may lead to reduce water consumption significantly, thereby availing environmental sustainability. This study was undertaken to explore the possibility of minimizing water use in the cotton knit dyeing process without hampering the fabric quality and find out the resulting environmental and economic benefits. Currently, there are no published color-wise water consumption data for dyeing one kg of knit fabric available from Bangladesh cotton knit dyeing industries. Therefore, the primary information about water consumption has been generated by site visiting and auditing bulk production of some selected cotton knit dyeing industries. Material balance and right first time (RFT) approaches are exploited for generating stepwise water consumption scenarios. Minimum volume of adequate water required for each reactive dyeing has been estimated. The total volume of water consumed by cotton knit dyeing industries of Bangladesh was about 85.87 million cubic meters in the year 2019–2020. It has been estimated that 1 L less water consumption to produce 1 kg of fabric can save 7.80 percent of chemical cost. These estimates suggest that it is imperative to monitor every dyeing step carefully for reducing water consumption without compromising the quality of dyeing and fabric. The analyses of the collected knit dyeing processing data reveal that water consumption quantity varies with the factors like design of the dyeing machine, efficiency of the machine pump, types of wet processing and fabric, know-how (knowledge) and with adaptation of new technologies or processes. Many new approaches can be brought into practice to minimize water use during cotton knit dyeing processes. Finally, some sustainable alternative technologies, prospective techniques and recommendations are set forth based on the authors' extensive inspection, experience, spill-off knowledge and received information from previous studies to prompt economical use of water, thereby reducing water consumption in cotton knit dyeing industries of Bangladesh. The study concludes that predictive approaches, along with preventive measures for the reduction of water consumption in dyeing processes using sustainable technologies and practices, will make a paradigm shift from the reactive approach for wastewater management to the preservation of natural resources.

Water consumption optimization in cardboard industry by experimental design

AbstractThis work was performed into a cardboard plant in order to reduce the freshwater consumption. Statistical experimental design was applied to investigate the effect of cleaning program, ink colour class and detergent concentration on ink circuit cleaning operation of flexographic printing machines. The results indicated that the proposed models fitted well with residual ink removal and cleaning water consumption (R2 > 0.99). For a better residual ink removal of the first colour class, it is suitable to employ cleaning program number 1 with 2% of detergent. However, if a residual ink of second colour class has to be removed, cleaning program number 2 and 2% of detergent are appropriate. At the optimum conditions, the volume of water required for residual ink removal from flexographic machines can be reduced by up to 26%. These results can contribute to the development of water consumption reduction models in cardboard plants and clean production implementation.

Experimental Investigation into Flue Gas Water and Waste Heat Recovery Using a Purge Gas Ceramic Membrane Condenser.

The direct discharge of wet saturated flue gas from a coal-fired power plant boiler causes a lot of water and waste heat loss. An inorganic ceramic membrane condenser recovers water and waste heat from the flue gas, which has great significance to improve energy utilization efficiency and reduce water consumption. However, the flue gas temperature is relatively low; thus, it is difficult to effectively utilize waste heat. In this paper, it is attempted to use the boiler secondary air as the cooling medium of the ceramic membrane condenser to realize the flue gas waste heat reuse. Based on the above ideas, a purge gas ceramic membrane condenser experimental platform was built for the water and waste heat recovery from the flue gas, and the water and waste heat recovery characteristics and the purge gas outlet parameters were discussed. Simultaneously, the heat transfer resistance and water recovery power consumption are also analyzed. The experimental results show that the water and waste heat recovery characteristics are enhanced with the purge gas flow increases. Increasing the flue gas temperature will increase the water recovery rate and heat recovery power. The ceramic membrane transmission efficiency is a key factor in restricting the actual water recovery efficiency. The purge gas absorbs the water and waste heat from the flue gas, the purge gas temperature and moisture content are significantly increased, and the purge gas relative humidity is also close to saturation. The Biot number of the ceramic membrane condenser is about 3.2 × 10–3 to 1.9 × 10–2; thus, the ceramic membrane tube wall thermal resistance can be neglected. There is a temperature difference between the flue gas and the purge gas, and the entropy production value of the ceramic membrane condenser increases with the flue gas temperature increases by the irreversible process.

Improved Lignite Predrying System Integrated with Heat and Water Recovery from Wet Flue Gas at Lignite-Fired Power Plants: Energy and Water Conservation

To improve energy efficiency and reduce water consumption simultaneously in lignite-fired power plants, an improved lignite predrying system integrated with heat and water recovery from wet flue gas is proposed in this study. In the proposed system, the heat source for the lignite predrying system was the latent heat from the flue gas instead of the extracted steam, so the extracted steam could return to the turbine to generate more power. Moreover, both the water from the raw lignite and wet flue gas desulfurization (WFGD) processes were recovered, which minimized the water consumption of lignite-fired power plants. This study evaluated the energy- and water-saving potential of the proposed system at both air-cooling and wet-cooling power plants firing three types of lignite separately. The results showed that the higher the moisture content of lignite, the larger the net efficiency improvement and the make-up water rate reduction. The net efficiency improvement and make-up water rate reduction in power plants firing Yimin lignite reached 2.33% points and 0.370 t/MWh, respectively, at wet-cooling power plants, and 2.18% points and 0.443 t/MWh at air-cooling power plants. This means that zero water consumption can be achieved, and water and electricity can be output at the same time at air-cooling power plants. The technical and economic analysis showed that the net present value in 10-years of power plants firing different lignite types could reach 49.31, 36.19, and 16.44 million USD depending on the predry degree. The discounted payback period was 2.34–3.67 years, which showed good economic viability in all cases.

Complementary Nutrients in Decoupled Aquaponics Enhance Basil Performance

Aquaponics combines raising fish and growing plants by recycling water and nutrients to reduce water consumption and reliance on chemical fertilizers. Coupled aquaponics systems recirculate water between fish and plant crops, whereas decoupled systems send mineralized fish effluent and wastewater unidirectionally to an independent hydroponic loop. Decoupling enables changes to the water, such as pH adjustments and complementary nutrient additions, to promote plant performance. In this study, basil, Ocimum basilicum (L.), was transplanted into 4 L containers filled with decoupled aquaponic (DAP), nutrient-complemented decoupled aquaponic (DAP+), or chemical-based conventional hydroponic (CON) nutrient solutions and grown for 21 days at pH 5.8. Plants grown in DAP+ and CON had greater biomass, height, and Soil Plant Analysis Development (SPAD) chlorophyll index and lower root:shoot biomass ratios than those in DAP. Shoot fresh and dry biomass was 11% greater for CON than DAP+, while height, SPAD chlorophyll index, and root:shoot ratio did not differ. We concluded that added nutrients in DAP+ enhanced performance compared to DAP, and the biologically derived nutrition in DAP+ enhanced performance to be similar, but not equal, to CON. We cannot recommend specific adjustments to the targeted blend of complementary nutrients tested, but findings suggest that complementary nutrients are effective in decoupled aquaponics.

The paper takes the form of a systematic literature review to examine the main pillars of Industry 4.0 in the hospitality industry and discuss how these technologies could help combat climate change. We propose five conditions under which Industry 4.0 could help to combat climate change. First, in the hospitality industry, increased use of Industry 4.0 technologies induces an increase in energy efficiency and a reduction of GHG. Second, increased use of Industry 4.0 technologies induces a reduction in water consumption and an increase in water use efficiency. Third, increased use of Industry 4.0 technologies induces a reduction in food waste. Fourth, increased use of Industry 4.0 technologies can promote Circular Hospitality 4.0. Fifth, increased use of Industry 4.0 technologies helps to reduce transport and travel. Hospitality Industry 4.0 technologies offer new opportunities for enhancing sustainable development and reducing GHG emissions through the use of environmentally friendly approaches to achieve the Paris Agreement objectives.

Comparative Life Cycle Assessment (LCA) between standard gypsum ceiling tile and polyurethane gypsum ceiling tile

In this paper, the LCA of two gypsum ceiling tiles is compared, the first one is a traditional gypsum tile and the second is a new eco ceiling tile in which polyurethane foam waste has been incorporated. Both tiles were made at one of the largest gypsum tile factories in Europe. The life cycle assessment has been considered from cradle to grave for which the corresponding production stages have been defined. This includes the extraction and transportation of raw materials, the manufacturing process, transportation to the client, the use of the product and the end of its useful life. The results show that the tile with polyurethane has a better environmental performance than the standard commercial ceiling tile. This is quantified as a 14% reduction in energy consumption, a 14% reduction in CO2 emissions and a 25% reduction in water consumption compared with the standard tile, all the while maintaining the technical performance. An analysis of the results suggests that the new eco product has a competitive advantage on the market thanks to its environmental improvements and good technical performance.

Extraction of the Bacterial Extracellular Polysaccharide FucoPol by Membrane-Based Methods: Efficiency and Impact on Biopolymer Properties.

In this study, membrane-based methods were evaluated for the recovery of FucoPol, the fucose-rich exopolysaccharide (EPS) secreted by the bacterium Enterobacter A47, aiming at reducing the total water consumption and extraction time, while keeping a high product recovery, thus making the downstream procedure more sustainable and cost-effective. The optimized method involved ultrafiltration of the cell-free supernatant using a 30 kDa molecular weight cut-off (MWCO) membrane that allowed for a 37% reduction of the total water consumption and a 55% reduction of the extraction time, compared to the previously used method (diafiltration-ultrafiltration with a 100 kDa MWCO membrane). This change in the downstream procedure improved the product’s recovery (around 10% increase) and its purity, evidenced by the lower protein (8.2 wt%) and inorganic salts (4.0 wt%) contents of the samples (compared to 9.3 and 8.6 wt%, respectively, for the previously used method), without impacting FucoPol’s sugar and acyl groups composition, molecular mass distribution or thermal degradation profile. The biopolymer’s emulsion-forming and stabilizing capacity was also not affected (emulsification activity (EA) with olive oil, at a 2:3 ratio, of 98 ± 0% for all samples), while the rheological properties were improved (the zero-shear viscosity increased from 8.89 ± 0.62 Pa·s to 17.40 ± 0.04 Pa·s), which can be assigned to the higher purity degree of the extracted samples. These findings demonstrate a significant improvement in the downstream procedure raising FucoPol’s recovery, while reducing water consumption and operation time, key criteria in terms of process economic and environmental sustainability. Moreover, those changes improved the biopolymer’s rheological properties, known to significantly impact FucoPol’s utilization in cosmetic, pharmaceutical or food products.

Sustainable cultivation of Haematococcus pluvialis and Chromochloris zofingiensis for the production of astaxanthin and co‐products

AbstractLarge‐scale cultivation of microalgae for the production of high‐value compounds raises concerns on sustainability due to intense consumption of water resources. Use of wastewater for microalgae cultivation is considered a promising alternative, because it not only reduces water consumption, but also provides nutrients required for microalgae growth. In the present study, Haematococcus pluvialis and Chromochloris zofingiensis were cultivated in synthetic dairy wastewater (DWW) to identify the potential of developing high‐value product first biorefineries, with astaxanthin as the main product. H. pluvialis and C. zofingiensis cultivated in DWW achieved biomass concentrations of 0.55 ± 0.01 and 0.65 ± 0.01 g/L, respectively. Astaxanthin contents of 2.1 ± 0.1% and 0.4 ± 0.1% were observed in H. pluvialis and C. zofingiensis grown in DWW. Minimum freshwater consumption for cultivation was 69.93 L/gastaxanthin in control growth media, which could be eliminated by cultivation of microalgae in DWW. COD, TN, and TP removal efficiencies were in the range of 94%–96%, 79%–81%, and 57%–79%, respectively, indicating capability for simultaneous biomass production and phycoremediation. Presence of carbohydrates and lipids in residual biomass suggested the applicability as feedstock for biorefining. Potential avenues to integrate wastewater treatment, astaxanthin production, and valorization of residual biomass were discussed in context of high‐value product first biorefineries.

Agro Climatic Zoning of Saffron Culture in Miyaneh City by Using WLC Method and Remote Sensing Data

Recent continuous droughts and decreasing ground water tables have prompted efforts to improve irrigation schedules and introduce crops that need less water. A study was recently conducted to determine suitable zones for saffron in Miyaneh using Landsat-8 images and the weighted linear combination (WLC) method. Climatic and geographical indices for saffron cultivation in the region were for soil type, slope, soil moisture, and soil salinity. Parameters such as 30 years of data on climate, soil, and water conditions were collected from synoptic and climatologic stations such as Tabriz. Then, parameters were weighted using WLC for importance in each region. The data were transferred to expert choice and clustered, rated, and integrated to produce the last layer. The results showed that the southeastern and northwestern regions of Miyaneh, especially the banks of rivers and catchments, were identified as suitable places for saffron cultivation and that 28% of the area is in the suitable class, 36% in the relatively moderately suitable class, 20% in the critical suitability class, and the rest of the area, which covers about 16% of the area, is in the non-suitable class. Therefore, if it is possible to identify favorable areas for saffron cultivation according to the climatic requirements and it is possible in practice to achieve higher performance per unit area, that in itself will contribute to improved economic conditions and levels of income for farmers. Due to the special characteristics of saffron, substituting it for the cultivation of crops with high water requirements, such as onions, potatoes, tomatoes, etc., will help reduce water consumption.

АНТРОПОТЕХНОГЕННІ ЧИННИКИ ВПЛИВУ НА БЕЗПЕКУ ВОДОКОРИСТУВАННЯ В КОНТЕКСТІ УРБАНІСТИЧНИХ ПРОЦЕСІВ: ПРИЧИНИ, НАСЛІДКИ ТА МЕТОДИ ПРОТИДІЇ

Urbanization processes lead to an increase in water use and its contamination. The strengthened anthropogenic impact has caused an unfavorable situation in the hydrosphere in almost all regions of Ukraine. Amidst constant anthropogenic load and intensive change of the living environment due to urbanization processes, measures reducing the level of pollution of wastewater, groundwater, and atmospheric air come to the fore. The article systemizes the factors of anthropogenic impact on water use safety, namely: wastewater of atmospheric and industrial origin, groundwater pollution, acid precipitation, and an increase in technogenic sediments that are formed during the operation of industrial and economic facilities, etc. It is also noted that the major problems of urbanized areas are high air pollution and deterioration of water supply and sanitation infrastructure. They result in a deterioration of the quality of water resources, a growth of atmospheric air pollution, the number of anthropo-genic sediments, and diffuse pollution of the environment. The directions of minimizing the negative impact of anthropogenic sediments, air pollution, surface contaminated runoff from urban areas on the quality of water in water bodies and their ecological state are substantiated. The urbanization of territories causes an increase in the volume of wastewater from all water users, both individual citizens and enterprises of industry, housing and agriculture. Despite the different technologies of wastewater treatment, a great deal enters the environment without treatment due to the growing number and overloading of treatment plants. The directions of minimizing the negative impact of surface contaminated runoff from urban areas on the quality of water in water bodies and their ecological state are systematized. Measures of rational water use are proposed, in particular: reduction of water consumption in urbanized areas as a result of the use of a system of economic tools, resource-saving technologies; strengthening control over the discharge of industrial waste; use of low-waste technologies and water recycling; establishment of standards for wastewater discharge; creation of water protection zones in areas of groundwater supply and intake, etc.

The most critical place to make these improvements is in the spray arm design. With a good spray arm design, it can be reduced water consumption, energy consumption, and noise. In this study, we focus on a new spray arm design (studied by Arçelik) that increases efficiency. Also, we have obtained a geometrical interpretation of the new spray arm motion. We investigate the path followed by the new spray arm in $ 3- $dimensional Minkowski space and its projection on a plane. Finally, we present its three-dimensional and two-dimensional images.</p></abstract>

Use of Rainwater in a Hydroponic Greenhouse

The increase in population in the world is currently generating needs for basic resources such as food and even liquids, resulting in a shortage of food that affects families, likewise, hydroponics as an alternative way to produce food with greater profitability and a lower use of land, water and energy, since the rainy seasons have constantly undergone changes, which have affected the natural growth of crops giving a smaller amount of this which generates losses, for this reason a greenhouse is being implemented (hydroponic) since they are more profitable and easier to control, which makes it an alternative to combat food shortages. To contextualize in the following paragraphs, an alternative method will be shown that allows the collection of rainwater that is used to harvest plants without the need for land through a closed system of 100% use. The system has a recollection of water by galvanized sheet roof capturing rainwater and storing it in 3 tanks with a capacity of 20L. They are connected in series which will replenish a 150L capacity tub containing tilapia fish. The tilapia´s waste will allow the vegetables to be nourished by means of a pump. It is proposed to use a hydroponic greenhouse, to grow vegetables and use the waste of the wall as fertilizer since the physical and chemical factors of the water du0072ing the activities of hydroponics and recirculation aquaculture, mainly in relation to the amounts of macronutrients, is undoubtedly the accumulation of nutrients dissolved in the water and helps in the cultivation of tomatoes, lettuce, slices, and cilantro, thus reducing water consumption and contamination of the land.

Silica Application Facilitates Vegetative Growth of Winter Squash (<i>Cucurbita maxima</i> L.) Under Water-Saving Irrigation

Silicon (Si) is used to alleviate abiotic stress in plants. Applying siliceous fertilizer in combination with regulated deficit irrigation may reduce water consumption during plant vegetative growth period. In this study, winter squash ‘East Elite’ was irrigated with 0.5, 1.0, and 1.5 mM SiO₂ under a field capacity—that is, the water content of 60% (C60, water-saving irrigation). The SiO₂ treatments promoted plant growth including stem diameter, plant height and leaf number; however, the plant growth under water-saving irrigation was slightly (but significantly) lower than that under regular irrigation (C₈₀). Silicon application in the water-saving irrigation can increase the accumulation of fresh and dry weight in the aboveground and underground of plant, but there is no significant difference between the treatments with different concentrations of silicon. Silicon application treatments was significantly higher chlorophyll content (SPAD) than C₆₀, and followed by C₈₀. The SiO₂ in the plants increased with increasing SiO₂ treatment concentration; however, the difference was nonsignificant. The 1.0 and 1.5 mM treatments increased the leaf transpiration rate and stomatal conductance. The growth of the plants treated with 1.5 mM SiO₂ was greater than that of the plants left untreated. The 1.5 mM SiO₂ treatment increased the activity of leaf catalase and peroxidase and reduced the leaf malondialdehyde content of the mild water stressed plants. Irrigation with a SiO₂ solution in a water-saving irrigation system can stabilize plant growth and increase water use efficiency.

Ultrasound imaging of liquid fraction in foam

Flotation is an important process in liquid-solid and solid-solid separation, whereby desired solids in suspensions are recovered by their attachment to gas bubbles. Monitoring the process is essential for an increased grade and reduced water consumption. However, in situ measurements of the froth’s phases (liquid, air, particles) and / or volume flow that would be easily integrable in industrial processes are not available. The constant alternation of phases remains challenging for measurement instrumentations. In this paper, we report on pilot tests of novel instrumentation that allows for measurement of low liquid fraction based on electrodes and ultrasound transducers measurements. It offers high milliscale spatial and temporal resolution in the low liquid fraction range of foam (≤ 0.83∙10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-2</sup> ). Improving the accuracy of prospective volume flow estimations, a high penetration depth of 9.2 cm was achieved. The measurement system was calibrated using homogeneous, steady foam and an integral conductivity measurement. A backscatter model was applied to reduce the effect of ultrasound shadowing and enhance quantitative liquid fraction estimates. Additionally, six cases of inhomogeneous and dynamic liquid fraction distributions were investigated qualitatively. The quantitative and qualitative validation was conducted with a reference neutron radiography measurement, showing good correspondence. This investigation distinguished between two of the three froth phases within the analyzed range. Whereby a first step towards in situ monitoring of foam parameters in industrial applications was achieved, which is especially relevant to widely used froth flotation processes.

REDUCING THE AGGREGATIVE STABILITY OF EMULSION STYRENE BUTADIENE RUBBER WITH THE USE OF AROMATIC AMINES

In this paper, for the first time, a study was conducted on the use of various types of aro-matic amines in the production of emulsion rubbers to reduce the aggregative stability of latex dispersions. The use of aromatic hydrocarbons containing amine groupsin the technology of sep-aration of rubber from latex makes it possible to obtain emulsion rubbers at low costs of the coag-ulating agent. It was found that the temperature regime of the coagulation process of the latex system has a significant effect on the consumption of aromatic amines used: the lowest consump-tion was noted when using them to reduce the aggregate stability of latex systems at temperatures not exceeding 20 °C. The consumption of the acidifying agent -15 kg/t of rubber. Low amounts of coagulating agent create good prerequisites for the implementation of a closed technological cycle on an industrial scale, reducing water consumption by rubber extraction workshops from latex, which ultimately increases the environmental friendliness of the entire technological process of their production. The analysis of rubbers as well as the physical and mechanical characteristics of vulcanizates prepared on their basis, showed that the main properties of rubber-technical products, from control and experimental samplescomply with the regulatory requirements of GOST and TU.
