Abstract:
A water treatment method according to the present invention comprises adding an amphoteric polymer flocculant to polluted water to flocculate suspended solids so that the polluted water becomes treated water, and filtering the treated water. An inorganic flocculent can be added to the treated water after flocculation treatment before filtering the treated water.
