The Potential of Ultrasonic Membrane Anaerobic System (UMAS) in Treating Slaughterhouse Wastewater

In the wake of energy crisis and the drive to reduce CO2 emissions, the alternative energy sources are much demanded in order to reduce energy consumption, to meet legal requirements on emissions, and for cost reduction and increased quality. The direct discharge of slaughterhouse wastewater causes...
