The distillery spent wash (DSW) from bioethanol industries has a very high chemical oxygen demand (COD). Hence, the goal of this study is to investigate the effect of currents (, 3 and A) and initial pHs (, and ) on electrocoagulation (EC) to decrease the COD in DSW. The results showed that the EC at the current of A enabled a higher COD removal efficiency (%) than
distillery spent wash concentrate upto % of heat / coal substitution with the similar characteristics as given in Annexure V. SPCBs/PCCs shall grant permission for regular coprocessing with copy endorsed to CPCB, within 45 days from the date of receipt of the application. b) However, Cement Industries planning for the coprocessing of spent wash
Specifically focusing for more than 4 years of Ramp; D on distillery spent wash treatment we have successfully treated distillery spent wash with combined TOD values up to 2,20,000 ppm., The treated water is fit for entire nonpotable requirements of industries as well as fertiirrigation.
Distillery spent wash is a highorganic liquid waste product generated during alcohol production. Typically, the organic load of spent wash is reduced through biomethanation by which organic material is microbiologically converted under anaerobic conditions to biogas. The resulting waste stream is referred to as biomethanated spent wash.
Chakraborty and Bhaskar carried out Pilot study plant to recover potassium salts from spent wash of a molasses distillery in India. In this process, the raw spent wash was neutralized with lime and evaporated about 75% solid in a forced circulation evaporator under vacuum by duplicating a
Distillery spent wash (DSW) is an extremely cumbersome and recalcitrant effluent. The present technologies are implemented for the industry to remove certain pollutants like chemical oxygen demand
3 of spent wash. The plant was claimed to achieved a COD removal efficiency of 86% with a HRT of 10 days and the biogas production was around 450500 m3/day. Another moderate sized chemical unit, having captive distillery is manufacturing 55000 KL of alcohol per year. Its distillery produces an effluent spent wash of about 1400 m3/day
Distillery spent wash is one of the 17 most high strength wastewater streams which are described by the Central Pollution Control Board. It is a wastewater stream generated from the primary column of the distillation process,, the Analyzer column. The average generation of the spent wash in a distillery ranges between 8 10
Sep 25, 2017#0183;#32; The distillery spent wash is hot, highly coloured and acidic, apart from containing high percentage of dissolved inorganic and organic matter, the latter being particularly responsible for high biochemical oxygen demand ( BOD ) and the polluting nature of the waste. Spent wash, contains dissolved salts and has a persistent dark brown color.
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 amp; []
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 standards imposed on effluent quality, untreated or partially treated effluent very often finds access to watercourses. The distillery wastewater with its

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.
There are a number of methods to treat distillery spent wash specially decolourization and removal of COD such as physical, chemical and biological methods. Biomethanation of distillery spent wash followed by aerobic treatment is the commonly used treatment to treat distillery . Aerobic treatment reduces the chemical oxygen demand (COD), and Biological oxygen demand up to 50 to 70 %, but till

Distillery Spent Wash (DSW) is a rich source of organic matter and nutrients like nitrogen, phosphorus, potassium, calcium and sulfur. In addition, it contains sufficient amount of micronutrients such as iron, zinc, copper, manganese, boron, and molybdenum. Vinasse incineration can claim to be the best viable solution to treat distillery
9/2/2014#0183;#32;Distillery spent wash does not contain any toxic heavy metals and being of plant origin and rich in nutrient contents may serve as a good fertilizer for crops, more effective than inorganic or mixed fertilizers being used by farmers. Distillery effluents were once regarded as

The disposal of wastes from industrial sources is becoming a serious problem throughout the world. In India, a total of approximately 40 million m 3 of distillery spent wash is generated annually from 295 distilleries. The distillery spent wash is acidic and high levels of biological oxygen demand and chemical oxygen demand and contains nutrient elements such as potassium (K), nitrogen (N
Experiment was performed by taking 1000ml distillery Biomethanated spent wash in a plastic tray, combination of electrodes were used such as aluminumaluminum (AlAl). The direct current applied was 15 Volts with a current density mA/cm2. Power supply is applied started at t=0 and at a regular interval of 30 minutes sample was
