Spent wash being plant originated, contains large quantities of soluble organic matter and plant nutrients, therefore, spent wash if utilized rationally and in appropriate concentration for crop production can prove to be a good source of nutrients and is expected to solve the problem of waste disposal.
Abstract. The impact of irrigation of distillery spent on the nutrients uptake in pulses in untreated and treated soil were studied. The 50% and 33% concentrations of spent wash were analyzed for their additive plant nutrients such as nitrogen, phosphorous, potassium and .
In this study, palm oil mill effluent (POME) was solubilized by batch thermoalkaline pretreatments. A threefactor central composite design (CCD) was applied to identify the optimum COD solubilization condition. The individual and interactive effects of three factors, temperature, NaOH concentrati .
spent wash by installing /multiple effect evaporators etc for achieving 50% reduction in volume of spent wash. The requirement of press mud as well as the land for making compost also gets substantially reduced, strictly adhering to the protocol for making bio compost.

Distillery Industry Effluent. The main source of pollution from distilleries is the Spent Wash – a nontoxic biodegradable effluent. A huge amount of effluent is generated in the distilleries, as per experience 1015 KL of distillery effluent is generated for production of 1 KL of Alcohol.
Mar 15, 2017· The adverse environmental effects of disposal of untreated spent wash are avoided, but the high energy demand of the evaporation process that will in most cases be met by using fossil sources of energy should be taken into consideration. Composting: In this process, press mud generated from sugar mill is utilised to produce compost by mixing ...
Effect of one time postsown and presown application of Distillery spent wash on the growth and yield of maize crop. Botany Research International, 2(4):288294.
Jul 01, 2020· Coronavirus (COVID19) 5 Potential LongTerm Effects of COVID19 It''s a new virus, and experts are learning more each day about the ways it could affect you in the months following diagnosis.
Molasses based alcohol distilleries generate highly contaminated, dark coloured and foul smelling effluent (biomethanated spent wash, BMSW, also known as post methanated effluent). While the prevailing practices for treatment of alcohol distillery effluents operate on the premises of "liability management", high potassium content of spent wash (ca. 2% w/v in BMSW) offers an opportunity for ...
Abstract Distillery spent wash is the unwanted residual liquid waste generated during alcohol production and pollution caused by it is one of the most critical environmental issue. Despite...
A strategy using distillery spent wash as admixture in concrete is presented in this paper. The properties of fresh and hardened concrete made with distillery spent wash are presented and discussed. Proportions of % of distillery spent wash
Findings indicated stimulatory effect of low rate of crude spent wash (5 ml kg−1soil) on root and shoot growth and inhibitory effect of higher dose (100 ml kg−1soil) of both crude and digested spent wash, therefore, judicious application of spent wash will improve crop productivity and alleviate environmental pollution problems.
After reading this article you will learn about: 1. Chemical Composition of Distillery Effluent 2. Standards of Distillery Effluents 3. Protocols for Utilization of Distillery Effluent for Irrigation of Agricultural Crops. Chemical Composition of Distillery Effluent: Distillery effluent which is generally known as spent wash is a dark coloured waste and has high BOD [.]
The effects of different dilutions of fresh spent wash liquid (a dilute liquid organic matter with some fertilizer value) on salinity buildup in clay loam and silty clay soils and on the composition of soil leachates were studied. Results indicate that additions of dilute spent wash would not add soluble salts to the soil provided there was sufficient leaching of soil solution.
undertaken to study the effect of spent wash and chemical fertilizer on sugarcane (Saccharum officinarum L.) Material and Methods Field experiments were conducted during 200708 and 200910 at India Glycol Limited, Kashipur (Uttarakhand). The soil was sandyloam (sand 67%, 20 silt% and clay 12%), bulk density ...
Without spent wash 1 Shrinkage limit 2 Shrinkage ratio (R) With spent wash 1 Shrinkage limit 2 Shrinkage ratio (R) Soil samples were tested with and without spent wash replacement of water. From the above tests, the summary of the test results is given in following Table 6 and Table 7.
Apr 15, 2009· Disposal of distillery spent wash on land is equally hazardous to the vegetation. It is reported to reduce soil alkalinity and manganese availability, thus inhibiting seed germination .Kannan and Upreti reported highly toxic effects of raw distillery effluent on the growth and germination of Vigna radiata seeds even at low concentration of 5% (v/v).
For incineration of this waste (spent wash) it is necessary first to concentrate the waste, so that its ignition tS sustained and continuous. This concentration is usually carried out in multiple effect evaporators. Due to acidic pH and chloride contents of the spent wash, these multiple effect evaporators
Spent wash discharge has a highly deleterious effect on fish life. Spent wash also contains significant amounts of recalcitrant compounds which severely pollute the receiving bodies of water and present a serious health hazard to the rural and semiurban population that depend on such water bodies for drinking water and other requirements.
Inhibitory effects of digested and crude spent wash were also visible on bud sprouting and settling height, but 1:5 aqueous dilution of spent wash stimulated the early growth attributes. Such beneficial effects of diluted spent wash were observed in most of the sugarcane genotypes.
The spent wash and PTDE (Primary Treated Distillery Effluent) shows the higher values at all physicochemical parameters. All the values decreased with increasing dilution whereas dissolved oxygen was increased. Colour The colour of spent wash was found dark brown. The colour of spent wash is suspected due to presence of a
• Spent wash is a complex, multicomponent stream that is known to cause considerable fouling. CONCLUSION The characteristic of spent wash do not allow its discharge into a water body, hence it requires treatment. Biological treatment, especially with pure cultures, appears promising and possibly costeffective for color removal; however, the
Spent coffee grounds, however, do not represent a simple food waste and could be an environmental pollutant. Spent coffee grounds contain high levels of organic compounds that have various biological effects, including antioxidant, antimicrobial, and other activities (Xu et .
