The ethanol distillery generates a huge quantum of undesirable dark brown coloured wastewater called "Distillery Spent Wash" (DSW) or "Vinasse" which has high COD and BOD. Presently, the disposal of DSW sustainably and efficiently is a major scientific, engineering, economic and environmental challenge in front of the distillery industry.
Abstract The distillery sector is one of the seventeen categories of major polluting industries in India. These units generate large volume of dark brown color.

(The Ministry of Environment, Forests and Climate Change, Govt. of India, 2018) The Draft standards suggest that all molasses based distilleries will have the option of either concentrating the spent wash in MEE and/or R.O. systems to achieve 45-60% solids and incinerated in Boilers or they could concentrate the spent wash in MEE/RO systems to ...
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 10-15 KL of distillery effluent is generated for production of 1 KL of Alcohol.
effluent treatment is a meaningful proposition. The process of alcohol production from molasses generally produces 8-15 liters of spent wash for every liter of alcohol generated in India. With 329 distilleries together produce 3.2 billion liters of alcohol per annum and spent wash is around 30-40 billions liters. These liquid is dark

Spent wash is the approximately 13-16 times more by volume to that of the alcohol. It is highly organic brown in color. Spent wash having BOD 40000-60000 mg/lit and COD about 1, 20,000-1, 40,000 mg/lit. So it is very troublesome to treat spent wash. It is therefore obvious that some treatment is necessary to minimize the deleterious effects ...
Distilleries are among 17 most polluting industries in India (CPCB 2001–2002). Usually about 8–15 l of wastewater is generated for every liter of alcohol produced by the molasses-based distilleries called ''spent wash.'' The spent wash is characterized by extremely high chemical oxygen demand, biological oxygen demand, suspended solids,

Abstract In India bioethanol is mainly produced by the fermentation of diluted sugar cane molasses solution. After fermentation, alcohol is separated by distillation and the residual liquid is discharged as Distillery Spent Wash or effluent.
It has been claimed that the 290 odd distilleries in India produce 40 billion liters of effluents (spent wash) per annum with an annual value of Rs. 500 crores in terms of N, P, K, and S; 150 crores for micro nutrients and organics; a Rs. 100 crores saving in the annual environmental cost; Rs. 100 crores in terms of loss to fisheries; 500 ...

The ethanol distillery generates a huge quantum of undesirable dark brown coloured wastewater called "Distillery Spent Wash" (DSW) or "Vinasse" which has high COD and BOD. Presently, the disposal of DSW sustainably and efficiently is a major scientific, engineering, economic and environmental challenge in front of the distillery industry.
Specifically focusing for more than 4 years of R& D on distillery spent wash treatment we have successfully treated distillery spent wash with combined TOD values up to 2,20,000 ppm following toughest discharge norms!. The treated water is fit for entire non-potable requirements of industries as well as ferti-irrigation.
In the present study, anaerobic treatment of distillery wastewater (spent wash) was carried out on plant scale. Spent wash is characterized by high temperature (80-90 0C), low pH (4.0-4.5), dark brown colour, jagerry odor, high BOD (45000-60000 mg/l) and high COD (80000-120000 mg/l).
Distillery Spent wash is highly acidic, having strong odour, variety of recalcitrant colouring pigment as melanoidins, metal sulfides and phenolics are responsible for dark brown colour of spent ...
