Affected of Ameliorated Alkaline Water and Soil Amendments on Exchangeable Cation, Macro and Micronutrients in Sodic Soil under Drip Irrigation

The Field experiment was carried out at Anbil Dharmalingam Agricultural College and Research Institute, Tiruchirappalli using cotton (RCH- 20) as a test crop to examine the effect of ameliorated alkali water and soil amendments on soil properties, growth, and yield of hybrid cotton in sodic soil under drip irrigation. In this experiment, Drip irrigation with gypsum treatment water and drip irrigation with spent wash treatment water were used as main-plots treatments. Soil application of gypsum @ 50 % GR (5.2 t ha-1) and one time soil application of distillery spent wash @ 5 lakh litter ha-1 were imposed as sub-plot treatments. The treatment without amendments both under main plot and sub plots were used as control. The experiment was carried out using a strip-plot design with four replications. The application of additives through irrigation water (or) soil considerably decreased the pH of post-harvest soil. The soil exchangeable Ca and Mg were found significant due to soil application of amendments only and value ranged from 8.51 to 9.35 and 5.03 to 5.20 Cmol (p+) kg -1 respectively. The soil available nutrients N, P and K were found significant, and value range from 167 to 311, 15.4 to 21.5, 158 to 928 kg ha-1 respectively. The application distillery spent wash (DSW) and gypsum slightly increased the micronutrient cations range which from 4.80 to 6.85 mg kg-1 of Fe, 8.60 to 10.43 mg kg-1 of Mn, 0.64 to 0.88 of mg kg-1 of Zn, 1.10 to 1.42 mg kg-1 of Cu. The results of the field experiment revealed that application of amended alkali water and amended soil significantly increased all the growth and yield parameters of cotton. An increase in seed cotton yield of 701 and 544 kg ha-1 was recorded due to the application of gypsum treated water and DSW treated water respectively over control. Similarly, an increase of 773 and 973 kg ha-1 of seed cotton yield was recorded due to soil application of gypsum and DSW respectively over control. While considering the interaction effect, soil application of DSW along with gypsum bed treated water found to be the best for getting higher seed cotton yield (3015 kg ha-1) when compared to other treatment combination.

Arbuscular mycorrhizas accelerate the degradation of colour containing organic pollutants present in distillery spent wash leachates

Distillery spent wash (DSW) from molasses-based distilleries is being used as a low-cost alternative to chemical fertilizers in countries like India and Brazil. However, using DSW as a fertilizer substitute causes organic pollutant leaching, including melanoidins and caramel colourants that turn bodies of water dark brown. This study investigated the arbuscular mycorrhiza (AM) mediated degradation of organic pollutants in DSW.Mycorrhizal and non-mycorrhizal Sorghum bicolor were grown in microcosms for 16 weeks. The plants were fertilized with either raw DSW or Hoagland solution. Leachates draining from the microcosms after fertilization were collected three times in 30-day intervals. Each 30-day collection was preceded by two fertilizations. A gas chromatography-mass spectrometry comparative analyses of raw DSW with leachates of the third collection from mycorrhizal and non-mycorrhizal microcosms was made. Sixty-five and 42 complex organic compounds were detected in raw DSW and leachate collected from the non-mycorrhizal pots respectively. Only 26 compounds were detected in leachate collected from mycorrhizal pots. Absent from leachate of the mycorrhizal pots were: colour-containing organic compounds diacetone alcohol; 3-amino-2-cyano-6-methyl-6,7-dihydrothieno[2,3-b]pyrazine S-oxide; cyclohexane; 1,2-benzenedicarboxylic acid, butyl 8-methylnonyl ester; 2-pyrrolidinone; and acetic acid, dodecyl ester present in raw DSW. The results indicate that AM fungi can degrade organic pollutants in DSW.

Study of Organic Constituents in Distillery Spent wash and Primary Treated Distillery Effluent (PTDE) with Different Dilutions

Abstract: Effluent that is released from distillery industries is known as spent wash which is the main reason for the damaging they caused on the natural ecosystem if there is no proper pre-treatment performed. A proper study is to be performed to detail about the physicochemical property of the effluent such as color, odor, total dissolved solid (TDS), chemical oxygen demand (COD), pH, biochemical oxygen demand (BOD), electrical conductivity, dissolved oxygen which are considered as the important parameters which will indicate the level of pollution of the effluent from different industrial. The present study was conducted to investigate the physicochemical characteristic and organic constituents of one of the distillery effluent found in distillery factory in Duggavati near Harapanahalli (tq) Davanagere . In investigation done by us we observed that the sample is lower pH and highly acidic in nature, higher temperature, higher concentration of chemical oxygen demand (COD) and biochemical oxygen demand (BOD) have been recorded. Disposing of the spent wash is one of the most important and present environmental problems faced by the world. The purpose of the study was to conduct and evaluate the physio-chemical characterization of spent wash effluent and analysis of PTDE and PTDE diluted with 50% and 75% of water.

Relative evaluation of FeCl3 salts and its nanoparticles on methane yield and sulphide inhibition control during biomethanation of distillery spent wash

Distillery spent wash (DSW), a complex wastewater rich in sulphates, organic matter and other contaminants when treated through anaerobic digestion process leads to digester failures due to sulphide inhibition and organic shock loading. Therefore, this work demonstrated the biomethanation of DSW to optimize the initial organic load (IOL) and substrate to inoculum (S/I) ratio in phase I experiments. In phase II, the impact of additives i.e., FeCl3 salts and its nanoparticles at optimized S/I ratio was investigated. The impact of S/I ratio, organic load and additives materials on methane yield, quality of biogas (H2S and CH4), microbial diversity and organic matter removal has been studied thoroughly. Results in phase I experiments disclosed that the dilution of wastewater to reduce COD/SO42− ratios favoured the process and the optimum IOL at which the maximum CH4 yield of 0.7 and 0.6 L/g CODR that can be achieved was 70 g/L and 35 g/L at an S/I ratio of 2:1 compared to control i.e., 0.3 L/g CODR. However, the H2S and CH4 in biogas ranged between 2 and 2.4 % and 60–64 % respectively. From phase II experiments, comparable CH4 yields of 0.67 and 0.65 L/g CODR were obtained by the application of FeCl3 NPs and salts at optimized IOL and S/I ratio but the H2S in biogas substantially decreased to <0.05 % and the CH4 improved to 72 %. Therefore, addition of FeCl3 either in the form of salts or NPs favoured biomethanation process and enhanced the overall performance.

The addition of carbon source is one of the practical ways to increase the C/N ratio and to promote the floc development in the culture system. The present research was carried out to assess the effect of distillery spent wash (DSW) at different C/N ratios on floc formation and growth of the shrimp under an intensive culture system. Methods: A 35-day experiment was conducted to study the effect of DSW at different C/N ratios (10, 15, 20 and 25) on the development of biofloc in the nursery culture of Penaeus vannamei. Floc development, water quality and growth performance of P. vannamei were also studied. Result: It was observed that significantly (p less than 0.05) higher specific growth rate (12.03±0.15), survival, final weight gain and better feed conversion ratio (1.25±0.02) of the shrimp at C/N 15 treatment. The study also recorded an increase in C/N ratio decreases the growth performance of the shrimp. The present study reported that, in a DSW based biofloc system, C/N ratio of 15 showed a positive effect on water quality parameters, survival and enhanced growth of cultured shrimp.

BIOHYDROGEN PRODUCTION USING DISTILLERY SPENT WASH IN A CSTR UNDER MESOPHILIC AND THERMOPHILIC CONDITIONS

To identify the viability and performance, distillery effluent having very high organic content was studied on continuous stirred tank reactor (CSTR). Under mesophilic and Thermophilic temperatures, different organic loading rates (OLR), optimum conditions for highest chemical oxygen demand (COD) removal and biogas generation was found at OLR of 3.72 to 42.16 kg COD/ (m3•d) and 4.21 to 43.17 kg COD/(m3•d). Highest COD exertion efficiency was found to be around 70% for OLR of 25.82 kg COD/(m3•d), when hydraulic retention time (HRT) reduced from 24 to 12 h at mesophilic condition. The steady state of hydrogen production was 1360 ml/l•d obtained at the OLR of 25.82 kg COD/(m3•d) with Volatile fatty acids to alkalinity ratio of 2.2 to 0.5 and the hydrogen production of 1130 ml/l.d obtained at the OLR of 28.52 kg COD/(m3•d) with a conversion coefficient of 1.8 to 0.5 Volatile fatty acids to alkalinity ratio were recorded in these stages. The maximum of 70% of the Distillery Spent Wash was converted to hydrogen at the OLR of 25.82 kg COD/(m3•d) at mesophlic conditions with HRT of 12 h and hence the mesophilic condition favoured the hydrogen production from Distillery Spent Wash.

Studies on Different Dilutions of Distillery Spentwash for Foliar Application and Its Effect on Soil Properties, Growth, Yield and Quality of Tomato

ABSTRACT A greenhouse experiment was conducted at GKVK Bengaluru, Karnataka during 2013 to decide the best dilution of distillery spentwash to be utilized as a foliar spray for tomato crop. Results revealed that a foliar application of 1:5 dilution of distillery spentwash resulted in higher growth parameters compared to other dilutions. Based on greenhouse experiment results, a two year field experiment was conducted in a farmer’s field at Mandya district, Karnataka during 2013 and 2014. Pooled analysis of two years of data (2013 and 2014) revealed that at 60 DAT, the treatment which received 100% RDF + 5 sprays of distillery spentwash at 1:5 dilution recorded significantly higher plant height (110.2 cm), SPAD meter reading (22.9) and higher fruit yield (7.14 kg plant−1 and 78.9 t ha−1) compared to other treatments. Lower plant height, SPAD reading and yield were recorded in the 100% RDF + water sprays (5 times). Also, significantly higher ascorbic acid content (54.2 mg 100–1) and lycopene content (14.0 mg 100–1) of tomato fruits were determined in the treatment receiving 100% RDF + 5 sprays of distillery spentwash at 1:5 dilution. After harvest of tomato crop, soil properties were higher in treatment which received 100% RDF + 5 sprays of undiluted distillery spentwash; but soil pH was higher in the treatment that received water spray.

The Energetic Aspect of Organic Wastes Addition on Sewage Sludge Anaerobic Digestion: A Laboratory Investigation

One of the possibilities to achieve energy neutrality of wastewater treatment plants (WWTPs) is the implementation of the anaerobic co-digestion strategy. However, a key factor in its successful implementation on the technical scale is the application of components with complementary composition to sewage sludge (SS). In the 7resent study, the influence of adding various co-substrates on the energy balance of anaerobic digestion was evaluated. The following organic wastes were used as additional components to SS: organic fraction of municipal solid waste (OFMSW) and distillery spent wash (DW) applied in two- and three-component systems. The experiments were performed in semi-flow anaerobic reactors with the volume of 40 L under mesophilic conditions (35 °C) at hydraulic retention time (HRT) of 20, 18, and 16 d. The application of substrates to SS resulted in enhancements of methane yields as compared to SS mono-digestion. The statistically significant differences were observed in tertiary mixtures at both HRT of 18 and 16 d. Therein, average values were 0.20 and 0.23 m3 kg−1VSadd at HRT of 18 and 16 d, respectively. Among all co-digestion series, the most beneficial effect on energy balance was found in 20% v/v DW presence in both two- and three-component systems at HRT of 16 d.

Electrochemical Degradation of DSW Using Fe- Fe and Al- Al Electrodes Taguchi and Anova Approach

Expulsion of toxins from distillery spent wash (DSW) was applied by utilizing a blend of matched aluminum and iron electrodes in a clump method of activity utilizing electrochemical procedure. The refinery spent wash was described diagnostically utilizing standard strategy for examination and the treatment results were dissected as far as COD and Colour. The examinations were directed to consider the impact of working boundaries, for example, voltage, separation between the electrodes and electrolysis time and were optimized by utilizing Taguchi and ANOVA technique. pH and stirring speed were kept constant as 7 and 500 rpm. The most extreme expulsion efficiencies of COD and Colour were monitored by considering total of 16 experiments each with three trials. The Taguchi method led to COD of 95% and color removal of 94%, optimized with Al-Al electrodes at the voltage of 25V, distance of electrodes 2 cm and the electrolysis time of 150 minutes. The most extreme COD and Colour removal efficiencies found to be 92% and 89% from Fe-Fe electrodes at the indistinguishable working conditions. In any case, the aluminum electrodes seen progressively appropriate for the deprivation of DSW when contrasted with iron electrodes.

​Effect of Distillery Spent Wash as Carbon Source in Biofloc System on Nutrient Profile of GIFT Tilapia

Background: Biofloc technology (BFT) is an ecofriendly aquaculture production system. In this, various carbon sources being used for floc production. However, the cheapest carbon source would make it economically feasible. In this context, the present study used purified distillery spent wash (DSW) as a carbon source to evaluate its viability on biofloc composition and carcass quality of GIFT strain. Methods: Nursery trial was conducted in high density poly ethylene (HDPE) outdoor lined pond (0.01 ha) for period of 30 days (8th January to 7th February 2018). In both BFT and control system, proximate composition and fatty acid profile of GIFT tilapia were analyzed at the end of the trial by following the standard method. Result: Dried microbial floc encompassed 16.61 ± 1.2% of crude protein and 15.3 ± 0.01% of linoleic acid. The Whole-body composition of GIFT was not significantly (P greater than 0.05) varied in between biofloc and control. Significantly (P less than 0.05) rich fatty acids found in biofloc fed GIFT whole body except stearic acid, behenic acid and docosahexaenoic acid. In the present study, DSW did not show much effect on carcass quality but showed better growth performance of GIFT strain in the BFT system.

Integrated use of distillery spent wash and NP fertilizers on FH-142 cotton-a low cost practice

Distillery spentwash, a sugar-industry discharge of plant origin generated during ethanol production can be used to fertilize the plants, instead of polluting the environment. A field experiment arranged in a split plot design consisted five spentwash spray concentrations (0, 5, 10, 15 and 20 %) as main split and four N-P rates i.e. 0, 1/3rd, 2/3rd and full recommended (0-0, 46-23, 93-46 and 140-70 kg N-P2O5 ha-1) as sub-split, replicated thrice. Increasing the concentration of spentwash or N-P fertilizer rates alone and their interaction significantly increased growth, yield and leaf tissue NPK concentration. Yet, increasing the rates of N-P alone from 1/3rd to full, did not increase the leaf tissue K concentration till foliar spray of spentwash. A full N-P fertilizer rate with 20% spentwash spray resulted in maximum plant height (130.77 cm), number of leaves (25.13), sympodia (20.12), squares (27.70), bolls (40.24) plant-1, seed cotton yield (4025 kg) ha-1 and leaf tissue N (3.40%) and P (0.20%) without any adverse effects on soil or cotton plant. However, increasing the rate of N-P fertilizer from 2/3rd to full or spentwash concentration from 15% to 20% did not influence the cotton attributes and yield. A 2/3rd N-P rate with 20% spentwash spray increased seed cotton yield by 20%, even over full N-P, which saved 1/3rd cost of each N-P and complete K, the best way to economize the chemical fertilizer inputs.

Effect of Value Added Product from Sugar Industry as a Potassium Source on Growth and Yield Attributes of Maize (Zea mays L.)

India is the major producer and consumer of sugar in the world. Molasses based distillery along with their product (alcohol) generate wastewater called as spent wash. It is acidic nature characterized by high BOD, COD value. The Value Added Product from sugar industry is generated by incineration of spent wash results in ash powder which is found to be rich in potassium. Consequently, a study was conducted to compare the effect of applying Value Added Product (VAP) as a potassic source on maize hybrid COHM(8) with that grown on Muriate of Potash (MOP) as a fertilizer source using a Randomized Complete Block Design with three replications. The treatments include absolute control (T1), 50% STCR (Soil Test Based Crop recommendation) -K through VAP (T2), 75% STCR-K through VAP (T3), 100% STCR-K through VAP (T4), 125% STCR-K through VAP (T5), 50% STCR-K through VAP + 50% STCR-K through inorganic fertilizers (T6) (MOP) and 100% STCR-K through inorganic fertilizer (MOP) (T7). The results showed that, 125% STCR-K as VAP produced better growth and yield characteristic, it was similar with 100 percent STCR-K as VAP and followed by 75 percent STCR-K as VAP when compared to control (T1). It is concluded that application of VAP from distillery spent wash (DSW) can be used as a substitute for inorganic potash fertilizer in maize crop cultivation to get higher yield and sustain soil health.

Sugarcane Distillery Spent Wash (DSW) as a Bio-Nutrient Supplement: A Win-Win Option for Sustainable Crop Production

Industrial pollution has been continuously soaring and causing serious threats to the soil, water, and air quality. The increase in industrialization has not only covered the large areas, but also created a large quantity of wastewater which is difficult to handle. The water produced from different industries is getting its place in the agriculture. However, the challenge is to properly use wastewater, so that the application of wastewater does not cause any soil and environmental problems. The distillery spent wash (DSW) is a liquid waste that is produced from the sugarcane industry. It contains a large load of both organic and inorganic substances. Also, DSW contains a sufficient amount of macronutrients (nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and Sulphur (S)) and micronutrients (zinc (Zn), copper (Cu), iron (Fe) and manganese (Mn)), which in turn improves the growth and yield of crops. The optimized doses of DSW substantially improve soil enzymatic and microbial activities, organic carbon, nutrient uptake, soil porosity, water holding capacity, aggregate stability, and anti-oxidant activities, which in turn improve the photosynthetic efficiency, growth and yield. However, the inadequate knowledge about the DSW characteristics and methods of its agricultural application present questions concerning environmental quality for groundwater pollution. Therefore, to obtain a better understanding about the DWS, here, we discussed the effects of DSW on soil quality, crop yield, and its implications for agriculture and water quality.
