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 standards imposed on effluent quality, untreated or partially treated effluent very often finds access to watercourses. …
anaerobically digested spent wash are shown in table 1. Therefore, spent wash needs a further treatment for its safe disposal in the environment. Due to very high organic content in the spent wash, favorable climatic conditions in India and methane gas recovery, anaerobic digestion is the primary treatment of spent wash.
Plausible pathway for the treatment of spent wash by focusing potential of carboxylic acids in the spent wash. 4. Conclusion. In conclusion, the present manuscript unbolts the new horizons for sustainable management of DSW to explore its potential for the production of commodity chemicals. To the best of our knowledge, this is the first report ...
Spent wash have high potential to produce methane gas and it is subjected to anaerobic digestion for methane recovery. Bio-methanation is an attractive primary treatment process which …
Biological treatment of distillery spent wash is either aerobic or anaerobic but in most cases a combination of both is used. A typical COD/BOD ratio of 1.8–1.9 indicates the suitability of the effluent for biological treatment [10]. Aerobic treatment of wastes with high organic load such as molasses is associated with operational ...
centrated wastes: high molecular weight membrane filtered spent wash (COD = 240 kg/m3), modified distillery spent wash (COD = 200 kg/m3), and vacuum-distilled spent wash (COD = 200 kg/m3) were used in this work to study their suitability for the proposed pretreatment process. Equipment. Experiments were performed using a laboratory
Ethanol distillery is the highest consumer of raw water (25–175 L/L of alcohol) for non-process applications, like cooling water, steam generation, etc. and the process consumption such as yeast propagation, molasses preparation [].The major sources of wastewater in molasses-based distilleries are: fermenter sludge, spent wash and spent lees as indicated in …

Distillery spent wash treatment of the yesteryears revolved round the open lagooning system with its inherent problems of land, odour and seepage into use and degradation and the ground water. ... to take care of compost yard machinery repairs and variation in seasonal utilisation of SW for composting. 2. Concentration and incineration not ...
A combined treatment technique consisting of enzymatic hydrolysis, followed by aerobic biological oxidation was investigated for the treatment of alcohol distillery spent wash. Sangave and Pandit ( Citation 2006a ) used cellulase enzyme for the pretreatment step with an intention of transforming the complex and large pollutant molecules into ...
Molasses based alcohol distilleries generate highly contaminated, dark coloured and foul smelling effluent (bio-methanated 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 …
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 …
After first stage bio machination digested spent wash is feeding into second stage up flow type four numbers of digester (460 m3 capacities each). Before second stage of bio machination fresh spent wash is also mixed with digester spent wash in small quantity. After two stage bio machination treatment digested spent wash used for Bio composting.
Anaerobic treatment is usually the first step of treatment employed for distillery spent wash and about 90% of COD is removed along with 80-90% BOD during the anaerobic treatment (Wolmarans and De ...
In October 2024, Tianzhong Machinery shipped a screw press machine to France, with a conveyor belt and an organic waste crusher, for fruit and vegetable waste treatment. Welcome … Shipping a JMS-160 Nut Butter Mill to Korea
Spent Caustic Treatment - 1 Sulfidic spent caustic from a steam cracker via the Caustic Wash Tower contains valuable sodium salts but contaminated with dissolved hydrocarbon, Red Oil polymers, and active polymer precursors. These contaminants can foul spent caustic treatment processing equipment and grossly inhibit the conversion level of sodium sulfide to its highest …
Keywords: Anaerobic Digestion, Spent Wash, Alcohol Production. Distillery spent wash refers to the effluent generated from alcohol distilleries. On an average, 8–15 L of effluent is generated for every litre of alcohol produced. The alcohol distilleries are extensively growing due to widespread industrial applications of
