ABSTRACT:
A novel sewage purification method is provided herein. The method includes adding particular amounts of at least alum, a cationic polyelectrolyte and an anionic surface active compound to the sewage or other impure water in any order, then turbulently mixing the added chemicals within the sewage or other impure water, then allowing particulate matter to settle as sludge, and finally drawing off pure water. Preferably, part of the sludge is recycled to the sewage or other impure water to be treated.
