Introduction: K'far Tabor WWTP uses activated sludge technology to treat domestic wastewater enriched with food industry wastewater (whey wastewater). The capacity treatment of K'far Tabor WWTP is 550 cubic meters per day of domestic wastewater. 

Treatment process: Raw wastewater drains into an anaerobic pond then follows to the bioreactor (external ring). The bioreactor (V= 350 cubic meter) is aerated and mix liquor flows clockwise and drains into the secondary clarifier (internal ring). The hydraulic retention time (HRT) is approximately 15 hours. The mix liquor continues into two secondary clarifiers for phase separation.  Sludge circulation (RAS – returned activated sludge) persists from the clarifier back into the anoxic pond. Excess sludge (WAS-waste sludge) is removed during the process.

Problem defined: The biological process suffered from casual stress episodes that were caused by the entry of high organic load. High organic load water that is entry into the treatment process, inducing stress episode of the biological process, thus reducing the treatment yield.

Treatment aim: To stabilize the biological process in order to improve the effluents quality.

SBP technology setup: 

Results: Significant effluents quality improvement and bio-treatment stability increases over time
