摘要: Pharmaceutical sludge is considered as a hazardous substance with high treatment and disposal fees. Anaerobic digestion could not only transform the into activated sludge, but also generate valuable biogas. This research had two objectives. First: studying feasibility of anaerobic determining biochemical methane potential (BMP) pharmaceutical under different Inoculum to substrate TS ratios (ISRs) 0, 0.65, 2.58 10.32 in mesophilic condition 37±1°C. Secondly, investigating removal efficiency colistin sulphate during digestion. The results showed that use treat feasible it can completely eliminate sulphate. highest biogas production from 499.46 mL/g at an ISR 10.32.
