The direct discharge of palm oil mill effluent (POME) wastewater
causes serious environmental pollution due to its high chemical
oxygen demand (COD) and biochemical oxygen demand (BOD).
Traditional ways for POME treatment have both economical and
environmental disadvantages.In this book, ultrasonic
assisted-membrane anaerobic system(UMAS)was used as an alternative,
cost effective method for treating POME. Six steady states were
attained as a part of a kinetic study that considered concentration
ranges of 8,220 to 15,400 mg/l for mixed liquor suspended solids
(MLSS) and 6,329 to 13,244 mg/l for mixed liquor volatile suspended
solids (MLVSS). Kinetic equations from Monod, Contois and Chen
& Hashimoto were employed to describe the kinetics of POME
treatment at organic loading rates ranging from 2 to 13 kg
COD/m3/d.throughout the experiment, the removal efficiency of COD
was from 94.8 to 96.5% with hydraulic retention time, HRT from
400.6 to 5.7 days.The growth yield coefficient, Y was found to be
0.62gVSS/g COD the specific microorganism decay rate was 0.21d-1
and the methane gas yield production rate was between 0.25 l/g
COD/d and 0.58 l/g C
