Approximately 400 KL of spent wash or vinasse per annum is generated at an average COD concentration of 100,000 mg/l, by over 250 distilleries in India. There is an urgent need to develop, assess and use ecofriendly methods for the disposal of this high strength wastewater. Therefore, an attempt was made to investigate a few aspects of anaerobic digestion of spent wash collected from a distille...

this study investigated the effect, on reactor performance and biomass retention inside the bed, of the material used to make the supports of anaerobic fixed-bed reactors. three inert supports of similar shape but made of three different materials polyvinyl chloride, polypropylene, high-density polyethylene were manufactured and used. all three supports had the same specific surface area but di...

Carbon dioxide from the biogas resulted in vinasse fermentation should be treated. One of methods that could reduce carbon was adsorption process. A chemical and physical process modify characteristic obtain activated as an adsorbent. Chemical activation using H2SO4 ranged 5% to 30%, pyrolysis at 400oC for 3 hours. The done by inserting 98.68% synthetic CO2 range 0.002 0.0058 L/min bottom colum...
