DESTABILIZATION OF SLUDGE WITH HYDROLYZED STARCH FLOCCULANTS

摘要

DESTABILIZATION OF SLUDGE WITH HYDROLYZED STARCH FLOCCULANTS of the Invention Hydrolyzed corn and potato starches are effective as flocculants in destabilizing dilute as well as thick sludge suspensions. Potato starch flocculants are equal to, or better than, the synthetic polyacrylamide flocculants in destabilizing sludge suspensions, especially when clarity of the suspension is a significant consideration. Among the potato starch flocculants which were found to be generally better than the corn starch flocculants, those containing A?PO4 were the best. Potato starch flocculants are equally effective on oil-removed and nooil-removed sludge suspensions.
