Acidogenic digestion of organic municipal solid waste in a pilot scale reactor: Effect of waste ratio and leachate recirculation and dilution on hydrolysis and medium chain fatty acid production

The purpose of this investigation is to study the effect 1) leachate recirculation (LR) and dilution (LD), 2) increment waste ratio, 3) co-digestion using poultry as co-substrate for enhancing acidogenesis process organic municipal solid (OMSW), thereby increasing medium chain fatty acids (MCFAs) production. results experiment carried in a batch pilot reactor show that LR increases hydrolysis well OMSW conversion efficiency. Meanwhile, highest total MCFA production around 62,000 mg/L shown with high ratio. Thus, concentration hexanoic acid lysimeters (5475 mg/L, 6627 10,889 respectively). However, metabolic shift toward heptanoic octanoic reported LD samples. Nonetheless, use multiplied produced MCFAs.
