Bioaugmentation Reduces Sludge Production 20% Allowing Digester to Handle Increased Load in Hod Hasharon, Israel - WASTEWATER TREATMENT
Hod Hasheron’s municipal waste treatment system includes anaerobic digesters utilized to reduce sludge volume before disposal. Average daily flow into the plant is approximately 25,000 M3/day. The overall performance efficiency of the plant is excellent.
Based on results achieved in the anaerobic digestors at Pusan and Empresas Publicas, the Operations Staff at Hod Hasharon made a decision to determine if similar results could be achieved in their plant. Unlike the other plants, Hod Hasharon was also interested in whether or not an increase in biogas production could be realized since they recovered the gas for use as a fuel source.
After the first three months of treatment with MICROBE-LIFT® technology, results were compared to historical values from the previous 15 month operating period. In spite of a 1.8% increase in loading to the plant based on a hydraulic and organic basis, the amount of sludge that was removed from the plant was reduced by 18% with a concurrent increase in biogas of 11.3%.
