Abstract

PURPOSE: To accelerate settlement of active sludge and to maintain a high MLSS in an aeration tank by adding a specific treating agent for active sludge settlement accelerator.
CONSTITUTION: In the waste water treatment using active sludge, at least one of manganese sand and manganese zeolite is added to the treaqment system as the settlement accelerator of active sludge. Preferable amount of manganese sand and mangane zeolite is 10W200wt% based on dried sludge. If the added quantity is less than 10wt%, the effect is insufficient, Effective location for addition is middle way of the aeration tank, settling tank, and sludge transportation pipe. Once added, these remain in the place until sludge is drawn out.
