6.4.1.2 Wastewater Generation and Characteristics
The main source of wastewater generation is the distillation step, wherein large volumes of
dark brown efuent (termed as spent wash, stillage, slop or vinasse) are generated in the tem-
perature range of 71–81°C. The characteristics of the spent wash depend on the raw material
used; also, it is estimated that 88% of the molasses constituents end up as waste. MSW has
