The potentials of the Integrated Ultrasonic Membrane Anaerobic System (IUMAS) as a single unit for industrial sugarcane wastewater treatment

Increasing the energy crisis makes it reconsider to reduce carbon dioxide reduction (CO2) emission. Due to finding the high chemical oxygen demand (COD), biochemical oxygen demand (BOD) and total suspended solids (TSS) in the discharge of sugarcane mill effluent (SCME) wastewater which causes the earnest environmental issue. Membrane fouling became one of the main problems facing wastewater treatment. The overview of the conventional methods of wastewater treatment is disadvantageous from both environmental and economic perspectives. This study investigated the first time treated the SCME wastewater by an alternative cost-effective ultrasonic membrane anaerobic system (UMAS). The obtained results showed that the mixed liquor suspended solids (MLSS) were in the range of (8500 to 14700) mg/L, while the mixed liquor volatile suspended solids (MLVSS) results were in the range of (5874 to 13068) mg/mL. Three kinetic models were applied to evaluate the kinetic patterns of sugar cane processing at organic loading rates in the range of (3-15) kg COD/m3 /d. UMAS showed a removal efficiency in the range of (94-96.3) % with hydraulic retention time from 280.5 to 9.8 days

Development of an integrated ultrasonic membrane anaerobic system (IUMAS) for palm oil mill effluent (POME) treatment

Biofouling is a critical issue in membrane water and wastewater treatment as it greatly compromises the efficiency of the treatment processes. It is difficult to control, and significant economic resources have been dedicated to the development of effective biofouling monitoring and control strategies. This manuscript introduces and investigates the potentials of an integrated ultrasonic membrane anaerobic system (IUMAS) as a single reactor unit to overcome membrane biofouling and retain the methane gas, CH4 in Pam oil mill effluent (POME) wastewater treatment. Six steady states were attained as a part of a kinetic study that considered concentration ranges of 11,760 to 18,400 mg/L for mixed liquor suspended solids (MLSS) and the mixed liquor volatile suspended solids (MLVSS) ranges from 9,000 to 16,008 mg/L. Steady state influent chemical oxygen demand, COD concentrations increased from 67,800 mg/L in the first steady to 82,700 mg/L in the sixth steady state. Kinetic equations from Monod, Contois, and Chen and Hashimoto were employed to describe the kinetics of POME treatment at organic loading rates ranging from 3 to 13 kg COD/m3/day. The chemical oxygen demand, COD removal efficiency was from 94% to 97% with hydraulic retention times, HRTs from 750 to 10 days. The methane gas yield production rate was between 0.21 and 0.55 l/g COD/day. The complete treatment reduced the COD content to 4,962 mg/L equivalent to a reduction of 94%
