Vinasse incineration with bagasse as a supporting fuel* [Full subscriber]

Abstract         Effluents from molasses-based distilleries called vinasse, spent wash, or slope are highly toxic in nature. It has very high BOD, COD, and low pH.  Indian industries have handled this vinasse through bio-composting or bio-methanation, but it still discharges a large quantity of effluent.  To minimize effluent discharge and at the same time to effectively utilize the heat potential in vinasse, an alternative is to incinerate it.  Incineration can contribute to the steam and power production of factories.  Vinasse has a calorific value that is not sufficient to sustain combustion.  Hence, for incineration, support fuel is required to enable sustainable…
