Evaluation of Biogas Through Chemically Treated Cottonseed Hull in Anaerobic Digestion With/Without Cow Dung: an Experimental Study

Cow dung is generally used as the feedstock material for anaerobic digestion to produce biogas. A selection of alternate biomass needed reduce consumption or eliminate use cow dung. Recently, cottonseed hull has been considered primary substrate In this paper, effect biogas production on co-digestion CD with pre-treated CSH using sulfuric acid, hydrochloric hydrogen per oxide, and acetic acid investigated. The concentration each varied 1%, 2%, 3%. addition, two alkaline, namely, sodium hydroxide calcium hydroxide, are at different concentrations 4%, 6%, 8%. yield obtained from mono-digestion chemically treated ratio 75:25 (CD: CSH) experimental results compared. enhancement batch reactors mesophilic temperature where mono- co-digested acid-treated alkaline-treated cotton seed observed maximum achieved 6% NaOH that offers 13-fold improvement over untreated during mono-digestion. Whereas in co-digestion, it a 6-fold Ca(OH)2.
