Optimization of Magnetic Biochar Preparation Process, Based on Methylene Blue Adsorption

The search for low-cost and effective adsorbents for the removal of organic dyes from contaminated water is urgently needed. The substantial amount of waste mushroom cultivation substrates generated in practical production can serve as an ideal material for the preparation of adsorbents. In this study, we investigated the main control parameters affecting the performance of magnetic mushroom substrate biochar and optimized the process of preparing biochar by using the Plackett–Burman and central composite design methods. Various analytical techniques including SEM, EDX, BET, and VSM were used to characterize the biochar. The results indicate that the carbonization temperature had the most significant impact on the yield and adsorption performance of biochar. Under the conditions of a carbonization temperature of 600 °C, a carbonization retention time of 1 h, and an impregnation ratio of 0.1, the yield and methylene blue adsorption value of magnetic biochar were 42.54% and 2297.04 μg/g, respectively, with a specific surface area of 37.17 m2/g. This biochar effectively removed methylene blue from the solution, demonstrating a high economic efficiency for wastewater treatment and pollution control. Furthermore, the adsorption–desorption cycle studies revealed its excellent stability and reusability. Additionally, based on the response surface methodology, a three-dimensional surface model of the adsorption performance of magnetic biochar under different carbonization conditions was established, providing a theoretical basis for the preparation of magnetic biochar from agricultural wastes.

Water environment collaborative governance policy in the Yangtze River Delta

ABSTRACT Water environment collaborative governance is an important policy agenda during the Yangtze River Delta integration. Based on collaborative theory and policy value theory, this essay finds 144 water environment collaborative governance policies in the region from 2007 to 2022. It utilizes a policy collaborative model to discuss the water environment collaborative governance state at the regional and provincial levels in this region. Results show that 87.5% of water environment collaborative governance policies are enacted by local government in the region in this period, the main policy aims of which are water resource protection and wastewater pollution control. More policy attention will need to be paid to water environment restoration and off-office auditing of cadres. While administration policies and legal interventions are the main policy levers, economic policies and personal policies are relatively underused. Policy elements are significantly diversified at the provincial level in the region. In response to the findings above, this essay offers advice to improve water environment collaborative governance in the Yangtze River Delta region on four aspects: giving local governments full discretion in wastewater pollution treatment; giving full play of the water pollution control policies' value; adopting differentiated water pollution control policies; and strategies among the local government in the region, exerting policy stability.

Synergistic regulation of nanocomposite interlayered forward osmosis membranes with 1D/2D nanostructures for enhanced heavy metal retention

The treatment of heavy metal wastewater poses a significant challenge due to its adverse environmental consequences and potential hazards to human well-being, necessitating effective and sustainable solutions. Forward osmosis (FO) is an efficient and low-energy separation technology that serves as an effective strategy to address this issue. However, it still faces the trade-off between water permeability and selectivity, which directly impacts the solute separation efficiency and retention characteristics. In this study, a covalent organic framework (COF) interlayer was introduced via in-situ growth, and the surface properties of polyamide (PA) were synergistically regulated by amine-functionalized multi-wall carbon nanotubes (MWCNT-NH2), resulting in a 1D/2D nanocomposite interlayered FO membrane with a high crosslinking density, improved hydrophilicity, excellent stability, and antifouling properties. The synergistic effect of COF and MWCNT-NH2 led to an increase in the concentration of MPD participating in interfacial polymerization (IP) and a decrease in MPD diffusion rate. These improvements led to enhanced water permeability and selectivity, as well as outstanding retention efficiencies for heavy metal ions (Cr3+, Ni2+), exceeding 99.2 %. Therefore, this study holds significant implications for targeted application development of high-efficiency FO membranes in the future, demonstrating practical value in the treatment of heavy metal wastewater and environmental pollution control.

Advancements in organic pollutant remediation: The role of nitrogen-doped rGO-CeO2 in photocatalytic efficiency enhancement

In this work, a novel nitrogen-doped reduced graphene oxide-ceria (N-doped rGO-CeO2) photocatalyst was successfully synthesized and exhibited a notable capability in degrading various organic pollutants. Among the synthesized samples, rGO-CeO2-900 N2 demonstrated the most efficient photocatalytic activity, achieving a 77.43% degradation rate for tetracycline (TC) fitting the modified Elovich model (R2 = 0.99). The CeO2 addition can increase defects and amorphous carbon species in rGO in Raman spectra. The rGO adding and N doping can contribute to more effective separation of photo-excited electrons/holes (e-/h+) and a faster rate of charge transfer via the results of photochemical tests. With the combination between rGO and CeO2, the N doped rGO-CeO2 catalyst gains certain anti-H+ ability in TC degradation and more·O2- can be generated under light, while the N doping can form an impurity level N 2p in CeO2 and create additional reactive sites on the rGO. This N doped rGO-CeO2 photocatalyst is well-suited for the harmless degradation and offers significant potential in wastewater treatment and pollution control.

A 20-year shift in China's sewage sludge heavy metals and its feasibility of nutrient recovery in land use

Recycling resources from wastewater is even more important for developing a more sustainable society. Disposing sewage sludge, which accumulates most pollutants and resources in sewage, is the main challenge in wastewater pollution control and resource utilization. Heavy metals (HMs) are the greatest constraint limiting the application of sewage sludge to land as a sustainable use of this material. We conducted a meta-analysis of the concentrations of HMs in Chinese sewage sludge by combining data from studies published from 2000 to 2019 (N = 8477). Over this period, the reported concentrations of HMs in sewage sludge declined in three stages (a fluctuating stage, a slight decrease stage, and a rapid and stable decrease stage). The results revealed that economic development and environmental policy implementation were the main factors mitigating HM pollution in sewage sludge in China. Moreover, if environmental regulations were strengthened and HM pollution-mitigation strategies were made consistent, such that the proportion of sewage sludge applied to land in China could be increased from 18.6% to 48.0% (the proportion applied to land in the United States), the ecosystem services analysis showed that huge ecological–economic benefits could be realized (3.1 billion Chinese Yuan) and the use of fertilizers could be substantially reduced (the use of nitrogen fertilizers by 8.5% and the use of phosphate fertilizers by 18.1%). This review shows that China should formulate a unified policy and interdepartmental committee for sustainable application of sewage sludge to land and wastewater resource recycling management.

Wastewater Management Techniques: A Review

The wastewater treatment research is based on industrial processes and agriculturalwastewater treatment methods. Most of the river basins are closed to severe water storages, brought on by the simultaneous effects of agricultural growth, industrialization and urbanization. In these research the aerobic, anaerobic or the combination of methods used. Other than that an adsorption and coagulation have been applied to remove the pollution. The research on chemical industrial wastewater treatment was first studied on organic removal efficiency of a lab scale system using aerobic and anaerobic reactors. The aerobic waste water treatment as a reductive medium is receiving increased interest due to its low operation and maintenance costs and aerobic waste water treatment is easy to obtain. The primary goal of the wastewater treatment process is to eliminate various pollutants such as solids, organic carbon, nutrients, inorganic salts, metals, pathogens and so on effective wastewater treatment and disposal are critical for both environmental and public health reasons. The aim of wastewater treatment is to protect the environment and waste water management. The many research papers on wastewater pollution control studies, but very few research works is carried out for treatment of wastewater. The beneficial aspect of this paper is recycling, reuse of water. The industrial wastewater is divided into four categories: Chemical, Physical, Biological and mathematical approaches. In this main focused on the Biological methods viz. Aerobic and an aerobic.

Strategies for Improving the Performance of Sustainable Domestic Wastewater Treatment Plants

The West Java Provincial Government has inaugurated a community-based sanitation program in 18 Bandung Regencies. Especially in the Citarum watershed, domestic waste contributes 68% to river pollution and has water quality status over the past 10 years, showing 54% heavily polluted, 23% moderately polluted, 20% lightly polluted, and only 3% meeting quality standards. Efforts to improve domestic wastewater pollution control require the selection of technology that is influenced by many factors, so a theoretical and practical approach that pays attention to sustainability aspects is needed. Neglasari Village, Banjaran District, Sayati village, Margahayu district, and Cipaku village, Paseh District, are Kcamatan in Bandung Regency who have run the Sanimas program that has not met the muku standards, so it is necessary to improve the performance of the Sanimas wastewater treatment plant that is sustainable. From the location of the S animal wastewater treatment plant spread from the upper reaches of the river, the location of the Sanimas wastewater treatment plant is in a densely populated area and sanitation-prone area, also has the need to deal with sanitation problems. This research was conducted using the SWOT method. A SWOT analysis is performed to obtain recommendations for priority strategies.

Review: Wastewater Treatment in Different Industries

Abstract: Wastewater treatment is a process used to remove contaminants from wastewater and convert it into an effluent that can be returned to the water cycle. Once returned to the water cycle, the effluent creates an acceptable impact on the environment or is reused for various purposes (called water reclamation). The treatment process takes place in a wastewater treatment plant. There are several kinds of wastewater which are treated at the appropriate type of wastewater treatment plant. For domestic wastewater (also called municipal wastewater or sewage), the treatment plant is called a sewage treatment plant. For industrial wastewater, treatment either takes place in a separate industrial wastewater treatment plant, or in a sewage treatment plant (usually after some form of pre-treatment). Further types of wastewater treatment plants include agricultural wastewater treatment plants and leachate treatment plants. Processes commonly used in wastewater treatment include phase separation (such as sedimentation), biological and chemical processes (such as oxidation) or polishing. The main by-product from wastewater treatment plants is a type of sludge which is usually treated in the same or another wastewater treatment plant. Biogas can be another by-product if anaerobic treatment processes are used. Treated wastewater can be reused as reclaimed water. The main purpose of wastewater treatment is for the treated wastewater to be able to be disposed or reused safely. However, before it is treated, the options for disposal or reuse must be considered so the correct treatment process is used on the wastewater. Performance ofstate owned sewage treatment plants, for treating municipal waste water, and common effluent treatment plants, for treating effluent from small scale industries, is also not complying with prescribed standards. Thus, effluent from the treatment plants, often, not suitable for household purpose and reuse of the waste water is mostly restricted to agricultural and industrial purposes. The development of innovative technologies for treatment of wastewaters from various industries isa matter of alarming concern for us. Although many research papers have been reported on wastewater pollution control studies, but a very few research work is carried out for treatment of wastewater of steel industries, especially in reference to development ofdesign of industrial effluent Treatment Plants (ETP)system. Another beneficial aspect of this research work will be recycling, reuse of water and sludge from steel industry The whole technologies for treating industrial wastewater can be divided into four categories: - Chemical, Physical, Biological and mathematical approaches.

Effect of zero-valent iron and iron-carbon particles on the denitrification efficiency of anammox process under gradual cooling conditions

Nitrogen pollution in water bodies mainly comes from industrial wastewater discharge, urban sewage discharge, and agricultural pollution. Nitrogen in a nitrate form can adversely affect human health and the environment. In this study, the effects of adding zero-valent iron (ZVI) and iron-carbon (Fe-C) particles on the performance of the anaerobic ammonia oxidation (anammox) process and sludge properties under gradual cooling conditions were investigated. Inoculating a portion of mature anammox granular sludge can speed up the rapid start of anammox. After 90 d of domestication and cultivation, the sludge granulation was achieved, and the influent load was increased. After 30 d of incubation, the total nitrogen (TN) removal efficiency can reach 95.08%. Through batch tests, the short-term effects of adding ZVI and Fe-C particles on anammox sludge were studied. It was found that when 100 mg/L dosage of ZVI was added, the denitrification effect of anammox sludge is the best. When Fe-C particles with Fe/C ratio of 2:1 were added, the anammox sludge had the best denitrification effect. Fe-C particles addition increased the pH of the reaction environment and sludge activity was affected. Continuous flow experiments under gradual cooling conditions showed that the effect of adding Fe-C particles on anammox was better than that of ZVI. After adding ZVI under 15 °C, NH 4 + -N and NO 2 - -N removal efficiency was 78% and 86%. Compared with the low temperature non-dosing ZVI, TN removal load was 1.77 kg/(m 3 ·d), and efficiency was improved by 10.2%. Addition of Fe-C particles promoted the denitrification efficiency, NH 4 + -N and NO 2 - -N removal efficiency was 83.90% and 88.84%. As compared to control the TN removal load was 1.90 kg/(m 3 ·d), and efficiency was improved by 8.4%. The sludge concentration showed a positive correlation with temperature. Results from this study show that simple addition of ZVI and Fe-C particles can stimulate microorganisms to secrete more EPS even under lower temperature. The outcomes of study are significant for wastewater management and pollution control in the waterbodies.

A bibliometric analysis of research progress in sulfate-rich wastewater pollution control technology

Sustainable industrial development requires research on pollution control in industrial wastewater, particularly sulfate-rich wastewater, which poses a threat to the environment. This article differs from the previous sulfate wastewater treatment process and equipment review. Based on the quantitative analysis, this paper has determined some characteristics of the related literature on the pollution control technology of high-concentration sulfate wastewater to help researchers establish future research directions. From 1991–2020, the WoS database published 9473 articles related to high-concentration sulfate wastewater treatment technology. We used bibliometric analysis combined with social network analysis and s-curve technical analysis in this research. The United States was the first to start this type of research, Australia has insightful and instructive research articles in this area, and China is the most active in international cooperation. The keywords that appear most frequently in the dataset are degradation, adsorption, oxidation, reduction, and recovery. By S-curve fitting, it is known that biological treatment methods are closer to the maturity stage than physical and chemical treatment methods.

Recent advances in Microalgae-based distillery wastewater treatment

The growing trend in consumption and production of food products from brewing industries has led to an increased waste discharge of contaminants into the environment. The diversity of toxic non-biodegradable compounds present in the distillery wastewater (DWW) brings up a challenge for the researchers to explore more novel methods in the treatment process. More recently, microalgae-based bioremediation has gained significant importance in all kinds of wastewater treatment. Being eco-friendly and solar driven the potential value of this approach in DWW treatment however are yet to be fully exploited. Thus, in this review, we first describe the roles and applications of bacteria and fungi for treating melanoidins and other organic compounds present in the distillery effluent. Later, a special emphasis was given to the strategies that are involved in phycoremediation of DWW. At last, we intend to shed lights on research works related to microbial fuel cells and developing genetically engineered microalgae as a future prospect for improving the efficiency of phycoremediation in wastewater management and pollution control in the near future.

Catalytic ozonation of thymol with a novel CoCe-MMO catalyst: Kinetics and mechanism

In this study, a novel ozonation catalyst CoCe mixed metal oxide (CoCe-MMO) was prepared for the degradation of organic wastewater containing thymol. The results showed that the addition of CoCe-MMO could effectively enhance the effect of thymol degradation, and the thymol could be completely removed after 40 min of reaction. The reaction kinetics was calculated. It accords with the quasi-first order reaction kinetics, and the reaction rate constant is about 0.1357 min −1 . The enhancement mechanism was discussed and the CoCe-MMO could react with ozone to produce strong oxidizing free radicals-hydroxyl radicals (•OH). The catalyst was characterized by XRD, SEM, and XPS. The results showed that the catalyst continued the lamellar laminated structure of its precursor, and present a higher crystallinity and smaller crystal grain size (about 58-70 nm), which would promote the production of •OH. The •OH and O 3 could attack the ortho-position of thymol for peacekeeping, making it gradually converted into small molecule acids, and finally completely degraded into CO 2 and H 2 O. The stability and reusability of the catalyst were also studied and the CoCe-MMO catalyst could maintain high activity after three cycles. And the metal ion leaching rates of Co and Ce are 0.39 mg/L and 0.03 mg/L respectively, which is lower than the emission standard. This paper showed that the catalyst has good application prospect and could provide technical support for pharmaceutical wastewater pollution control with catalytic ozonation.

EFFECT OF RECYCLING OF ELEMENTAL CHLORINE FREE BLEACHING EFFLUENT TREATED BY ELECTROCOAGULATION ON PAPER PROPERTIES

This study aimed to determine the effect of recycling elemental chlorine free (ECF) bleaching effluent (D0EpD1 and OD0EpD1) after treatment through electrocoagulation under optimum conditions on paper properties. The effect of pH, current density, time and dose of electrolyte on the reduction of chemical oxygen demand (COD) and color was studied. Maximum decrease in COD and color was found under optimum conditions (i.e., pH 7, treatment time of 30 min, current density of 29.16 mA/cm2, and 1 g/L NaCl). Under these optimum conditions, the reduction in COD and color was of 79.9% and 99.10%, respectively. The reduction in the strength properties of paper, caused by recycling, was found to be insignificant, but a decline of 2.11% for D0EpD1 and of 1.43% for OD0EpD1 in brightness was found. Using the electrocoagulation method to treat the bleaching effluent can prove to have valuable potential towards wastewater utilization, pollution control, and sustainable development of the industry.

Adsorptive removal of methylene blue and acid orange 10 dyes from aqueous solutions using oil palm wastes-derived activated carbons

Presence of toxic dyes in industrial wastewaters deteriorates the environment. Wastewater pollution control using locally obtainable agricultural by-products could be an eco-friendly and sustainable strategy. Efficiencies of activated carbons (AC) developed from empty fruit bunches (EFB) and mesocarp fibers (MF) of oil palm were evaluated in methylene blue (MB) and Acid orange 10 (AO10) dyes removal. Impacts of operational parameters including adsorbent dose, pH, initial concentration of dyes, and contact time were examined on dyes adsorption. Maximum adsorption values of MB (24.00 mg/g) and AO10 (18.76 mg/g) were achieved at pH 2 and 3, respectively, 50 mg/L initial dyes concentration, adsorbents dosage of 5 g/L, and 90 min contact time. Evaluation of adsorption isotherms revealed that the Freundlich model provided the best fit to the empirical data (R2 ≥ 0.692). MB isotherm through MF, however, was better represented by Langmuir model (R2 = 0.979). MF activated carbon showed higher capacity in immobilization of both dyes probably due to its larger surface area (552.72 m2/g) and porosity (0.4458 cm3/g). Dye adsorption on to the activated carbons go along with pseudo-second order kinetic model.

Fabrication of Ag decorated g-C3N4/LaFeO3 Z-scheme heterojunction as highly efficient visible-light photocatalyst for degradation of methylene blue and tetracycline hydrochloride

The discharge of industrial wastewater poses serious concerns to the environment and human health. Therefore, urgent development of simple and efficient catalysts for removal of pollutants is required. In this study, a novel ternary nanocomposite Ag/g-C3N4/LaFeO3 (A/CN/LFO) was synthesized for the degradation of dye and pharmaceutical wastewater. The catalyst was prepared by decorating Ag nanoparticles (NPs) on g-C3N4/LaFeO3 (CN/LFO) Z-scheme heterojunction and formation of Schottky junctions with LaFeO3 (LFO) and g-C3N4 (CN). The formed hybrid structure between metal and Z-scheme heterojunction induced directional transfer of electrons or holes from the Z-scheme heterojunction to metal, providing maximum separation between electrons and holes for more efficient redox reactions. Consequently, the ternary nanocomposite displayed optimized efficiencies toward the photocatalytic degradation of methylene blue (MB) and tetracycline hydrochloride (TC) under visible-light irradiation, estimated to 98.97% (90 min) and 94.93% (120 min), respectively. These values were almost 4.81 times and 3.88 times higher than those of pristine LaFeO3, respectively. The charge transfer mechanism and pollutant degradation pathway were also studied. The data revealed that Ag decorated Z-scheme heterojunction showed efficient light absorption and separation of photogenerated carriers, which might be useful for large-scale practical applications related to wastewater treatment and pollution control.

Evaluation of the bacteriological and physicochemical risk of hospital effluents: case of the Mohamed V hospital in Meknes

Like other countries, Morocco is committed to protecting environment. One of the actions is Law 28 00 on waste because it is harmful to environment and to health. However, hospital effluents are getting out of hand. This study looked at those at Mohamed V Hospital, which serves a population of almost 2 million people. The methodology relates to physicochemical and bacteriological analyzes of representative samples of these effluents by monthly samples over a period of one year. These were carried out in front of the four wings of the hospital between 11 a.m. and noon (maximum activity period). The search for bacteria of medical interest was carried out at the medical analysis laboratory of the Mohamed V hospital. The bacterial count as well as the physicochemical analyzes were carried out at the drinking water & wastewater pollution control laboratory of the Autonomous Distribution Authority of Water and Electricity of Meknes and of the environment and health laboratory of the Faculty of Sciences of Meknes. The results showed that some parameters correlate with others and that these effluents pose a threat to the environment and to health. Indeed, the chemical pollution values are high (NH4 +, NO2-, NO3-) compared to WHO standards. The presence of pathogenic germs is demonstrated such as pseudomonas, acinetobacter, clostridium, staphylococcus and streptococcus. On the other hand, these effluents are biodegradable since the COD / DBOS ratio varies between 1.1 and 2 (<2).

Preparation and electrochemical treatment application of Ti/Sb–SnO2-Eu&rGO electrode in the degradation of clothianidin wastewater

This work investigated the preparation of Ti/Sb–SnO2 electrode co-doped with graphene and europium and the electrochemical degradation of clothianidin in aqueous solution with Ti/Sb–SnO2-Eu&rGO electrode. The physicochemical properties of different electrodes were characterized by using the scanning electron microscopy, X-ray diffraction, oxygen evolution potential and cyclic voltammetry tests. The results indicated that the Ti/Sb–SnO2-Eu&rGO electrodes have a compact structure and fine grain size and have a higher oxygen evolution overpotential than Ti/Sb–SnO2-None, Ti/Sb–SnO2-Eu and Ti/Sb–SnO2-rGO electrodes. Among the four electrodes, the Ti/Sb–SnO2-Eu&rGO electrode showed the highest efficiency and was chosen as the experimental electrode. The main influence factors on the degradation of clothianidin, such as initial pH, electrolyte concentration, current density and initial concentration of clothianidin, were analyzed. The results showed that the removal rate of clothianidin can reach 96.44% under the optimal conditions for 120 min treatment. Moreover, a possible degradation pathway including the fracture of internal bonds of clothianidin such as the N–N bond, the C–N bond that connects nitroguanidine to the thiazole ring and mineralization was elucidated by intermediate products identified by HPLC-MS method and Fourier transform infrared spectroscopy (FTIR). This paper introduces the Ti/Sb–SnO2-Eu&rGO electrode into an electrocatalytic degradation system and could provide basic data and technique support and guidance for the clothianidin wastewater pollution control.
