Abstract

PURPOSE:To dehydrate efficiently a surplus sludge by adding a part of flocculant to the sludge and homogenizing them, and then adding the rest flocculant and agitating them. CONSTITUTION:A necessary amount of an aq. solution of a flocculant for a surplus sludge is added dividedly in two times. The ratio of the first dose to the second one can be varied in a wide range centered around 1:1. But the efficiency falls down in the case that this ratio is too large or too small. Profitability of the process is improved by this method.
