Abstract

PURPOSE: To cut mould microbes and prevent bulking phenomenon by providing multi number of projections on the inside of the pump casing so that they pass while being intermittently engaged in the multi number of notched parts made on the extension of the rotary blade.
CONSTITUTION: The activated liquid sludge precipitated and condensed in the sedimentation-separation tank flows into the pump through the sludge suction port 2 and is pressurized by the impeller 5. when the sludge moves to the peripheral part from the center part of the casing 1, it undergoes the strong shearing and sliding forces between the notched parts 7 on the extension of the impeller rotary blade 6 and the projections 8 fixed on the pump casing 1 which are to be engaged in the notched parts 7 off and on, the mould microbes are cut and the bulking phenomenon can be completely prevented.
