Much research has been conducted to generate biogas from POME but little was focused on the microbial characteristics of the POME which is important to gauge the efficiency in POME treatment. One of the most challenging problems is the management of palm oil mill effluent (POME). Anaerobic digestion is one of the appropriate therapy techniques for effluents containing elevated organic carbon concentrations such as effluent from palm oil mills (POME). Palm oil mill effluent is a colloidal suspension containing 95-96% water, 0.6-0.7% oil and 4-5% total solids, which include 2-4% suspended solids. Journal of Cleaner Production 2020 , … POME or Palm Oil Mill Effluent is an underutilized liquid waste stream from palm oil mills which is generated during the palm oil extraction/decanting process and often seen as a serious environmental issue but it is a very good source for biomethane production. Various methods such as tank digestion and facultative ponds; tank digestion and mechanical aeration; decanter and facultative ponds; anaerobic digestion and facultative ponds and so on, were reviewed, each with its merits and demerits in application. Moreover, the biogas produced during the anaerobic decomposition of POME in open pond systems is not recovered for utilization.
