Question

What is dry fermentation process?

(a) Water content between 55%-75%

(b) Water content between 85%-95%

(c) Water content between 80%-85%

(d) Water content between 0%-15%

I got this question in examination.

My question is based upon Anaerobic Treatment of Solid Wastes and Biogas Generation in portion Biotechnology for Solid Waste Management of Environmental Biotechnology

Answer 1

Right option is (a) Water content between 55%-75%

The explanation: Water content between 55%-75% is the most suitable for dry fermentation process with different moisture content for fermentation in the fermenters under anaerobic processing, whereas, Water content between 0%-15% is very dry and the solid wastes cannot be processed by dry fermentation process of anaerobic digestion, water content between 85%-95% and water content between 80%-85% is usually categorized as wet fermentation.
