Abstract

PURPOSE: To improve, in the case of generation of thread-like bulking, efficiency of precipitation of dirt by addition to the dirt of alkali matallic salts and (or) calkaline earths metallic salts so that thread-like bacteria contained in the dirt can be selectively weeded out in a short period of time without detriorating quality of water being treated.
