Problems in Distillery Waste Treatment (with Solutions)

Excess sulphate concentration in spent wash also leads to high H 2 S content in the biogas and other allied problems. Scrubbing the biogas with water or alkali as a H 2 S absorbent is a common solution for H2S removal. However, with this system, moisture content of the biogas could go up. Such system involves higher recurring costs.
