It has a high content of sugar and is locally available in low cost [5-7]. The major problem associated with the molasses industry is the production of large quantities of brown-colored effluents known as spent wash. It has been reported that molasses spent wash in alcohol fermentation is nearly 15 times of the total amount of alcohol produced [8].

The by-product of sugar industry- distillery spent wash, is the unwanted residual liquid waste generated during alcohol production and pollution caused by it is one of the most critical ...
Furthermore, molasses-based distilleries generates spent wash 12 to 15 times greater than the alcohol produced during the distillation process (Shinde et al., …
Average generation of spent wash is around 8-12 litres / litre of alcohol produced, depending on continuous or batch process and quality of molasses used etc. Thus the …
This would only mean about 24 KLD of concentrated or about 50 KLD of raw spent wash per day in a 3000 TPD cement kiln.This is a very small quantity as compared to the total spent wash available. Also the availability of willing cement mills, furnaces and TPPs may be limited in the area of the distillery.
Sugarcane is one of the best converter of solar energy into biomass and sugar. The biomass which contains fiber, lignin, pentosans and pith can be converted into value added products by application of suitable chemical, biochemical and microbial technologies. The processing of sugarcane generates bagasse, molasses and press …
10-15 liters of wastewater known as spent wash is produced. About 40 billion liters of spent wash is generated form distilleries in India [2]. 2. ALCOHOL MANUFACTURING PROCESS The distilleries use molasses as a raw material for production of alcohol. This molasses contain 7-8 % glucose, which is converted in to alcohol by fermentation process.
The high COD, Total Nitrogen and Phosphate contents of spent wash can result in eutrophication of natural water bodies. The methane emission factor for distilleries is 0.2 kg/kg COD. Raw spent wash discharge has a highly deleterious effect on fish life. Spent wash also contains significant amounts of recalcitrant
The pollution of distillery stillage depends on the quality of the substrates and the unit operations used for alcohol production, which means that the characteristics of stillage can differ between distilleries [15, 25].For every liter of alcohol produced, molasses-based distilleries usually generate about 8–15 L of stillage characterized by …
Molasses Distilleries • Spent wash is the main waste stream – It has a BOD 5 of about 30,000 to 60,000mg/lit – COD of about 1,00,000 mg/lit – pH – acidic (4 – 5) – Colour- dark brown – About 15% solids content – Ash contains Potash as K 2 O • Spent wash generation: about 8 to 15 litres
Distillery industries in several regions all over the world pose a serious risk, as it generates unpleasant compounds. Under such circumstances, it seeks an effective …
In the bioethanol industry, a polystyrene divinylbenzene copolymer resin with an active chloride site was used to decolorize spent wash from sugar beet molasses, and they were able to achieve about 92% decolorization over 1.5 h of reaction time with a loading of 5 g/00 mL (Krzywonos and Łapawa, 2012; Lameloise et al., 2015).
Distillery Industry Wastewater Treatment Overview of distillery industry. DILUTION– Molasses available from Indian sugar mills has a solid content varying between 76 and 90%.In diluter, solid concentration of molasses is brought down to 20-25o Brix.. FERMENTATION – Production of alcohol from fermentable sugars in molasses …
Distillery spent wash (DSW) is a major waste generated by the ethanol industry, and its use to produce value-added products augment benefits to sugar and ethanol industries.
Figure 1: Generation of spent wash Molasses from the sugar factory is the major constituent in the sugar Industry. Molasses is the by-product of sugar Industries. The effluent of distillery is known as spent wash. Spent wash is the approximately 13-16 times more by volume to that of the alcohol. It is highly organic brown in color. Following ...
The majority of distilleries use molasses as a feed stock. Ethyl alcohol is an important feed stock for the manufacturer of various chemicals. The effluent from the distillery is described as...
Anaerobically treated molasses-based distilleries spent wash is a major source of terrestrial and aquatic pollution due to the mixture of the various unknown organometallic compounds in discharged ...
Problems with Incineration of spent wash • Solids content of spent wash is to be brought to about 60% before firing into the furnace. • This brings the economics down as it is energy intensive. Also, damaging to the material of construction. • Spent wash is sticky • It swells (up to about 5 times the original volume) while heating
Quality and the characteristics of molasses spent wash were depending on the method of processing. Disposal of waste water from industries environment regulatory authorities have strict rule.

The sugar manufacturing process results in the generation of solid wastes which include sugarcane trash, bagasse, bagasse fly ash, PM and spent wash [7, 11, 12]. The ones which have more economic value are bagasse, molasses and filter PM . PM is the compressed sugar industry waste produced during filtration of cane juice [5, 13].
