Book excerpt: Sewage Sludge wastewater causes serious environmental pollution due to its high chemical oxygen demand (COD) and biological oxygen demand (BOD). Traditional methods of treating sewage sludge wastewater are disadvantages from both economic and environmental perspectives. In this study, the potentials of Ultrasonicated Membrane Anaerobic System (UMAS) in treating wastewater as an alternative and cost effective method was investigated. Waste sludge samples used in the study were collected from sewage treatment plant of INDAH WATER in Kuantan, Malaysia. The temperature during collection of the raw sewage sludge was 32 oC. The wastewater was stored in a cold room at 4 oC prior to use The study began with some characterization studies to provide understanding of fundamental issues such as conventional separation, ultrasonic and membrane separation. The aim was to obtain optimum operation conditions, maximum methane production as well as overall performance of UMAS in treating sewage sludge, upon which further development on wastewater processes could be developed. Four steady states were attained as a part of this study that considered concentration ranges from 6500 to 2.300 mg/l for mixed liquor suspended solid (MLSS). UMAS was used to treat the sewage sludge at organic loading rates ranging from 0.06 to 0.12 kg COD /M3/day, and throughout the experiment, the removal efficiency of COD was from 79% to 93% and the methane gas percentage was between 93 and 85. The ammonia and nitrogen removal efficiency were 56 - 77 and 56 - 72 percentage respectively. The reactor pH is slightly changing during the experimental period with values around 6.8, 7.1, 7.2 and 7.00 in steady state 1, 2, 3 and 4, respectively. The slight changes in the alkalinity levels of pH indicate process stability. The gas volume was measured daily using a 20-litre displacement bottle. Biogas from sewage digester usually contain 55% to 65% of methane, 35% to 45% of carbon dioxide and
