The "Pulse Transfer Thickening" capability of the ODS® pump enables it to remove sludge continuously from the settling tank, pumping sludge from the bottom of the sludge blanket at the rate at which it accumulates there. In other words, the pumping rate is automatically matched to the sludge accumulation rate. Required velocities are maintained automatically without any loss of the turbulent scouring velocity to keep solids in suspension and without risk of clogging the pipes. "Pulse Transfer Thickening" works efficiently no matter how low the sludge accumulation rate.
Based on the experiences encountered by treatment plants utilizing "Pulse Transfer Thickening", we find an average increase in sludge consistency of about 60%. This is because rather than drawing off hundreds of gallons of sludge in a timed cycle, as in conventional pumping systems, with the ODS® pump only 4.5 gallons of sludge is withdrawn with each pulse.
