  • Separation Of Suspended Particles By Flocculating Agents (AREA)

Abstract

PURPOSE: To hasten precipitating separation speed of flocks and minimize the volume of a flocculating precipitation tank or a precipitating tank, as a result, by a mechanism wherein an inorganic flocculating agent is added to exhaust water to form minute flocks and, subsequently, an org. flocculating agent is added to form large flocks.
CONSTITUTION: During flowing the exhaust water (raw water) received in a storage tank 11 to a flocculating tank 15 with a stirrer 17 through a pump 13 while turblent flow is formed, an inorg. flocculating agent is added in a substantially continuous manner and minute flocks with substantially uniform size are formed by continuously mixing the said flocculating agent and the exhaust water by forced flow motion. This minute flocks containing exhaust water is blended with an org. flocculating agent in a flocculating tank 15 with a stirrer 17 by operating a stirrer 17 while an org. flocculating agent is added to grow minute flocks to large flocks and its large flocks is eluted toward adjacent multistage precipitating tank 19 by overflowing the said large flocks corresponding to an introducing amount of the exhaust water to a flocculating tank 15.
