Abstract

PURPOSE: To lower the zeta potential of suspended particles and to improve the flocculation effect in a neutral region considerably by adding the flocculation active material producing bacteria belonging to the Dematiacea genus of black germ families to sea water thereby flocculating and settling polluting matter.
CONSTITUTION: Glycol or the like as a carbon source is put into an ordinary synthetic medium, for example, Czapek medium, and the germ of No.4257 deposited with BIKOKEN is inoculated to this and was clutured. Thence, the medium is heated for 5 minutes at 100°C, and is subjected to centrifugation at 3,000rpm/min, whereby funguns bodies are removed. Ethanol is added to the separated liquid to 30% concn., and the formed flocs are centrifugally separated. These are dissolved in water, after which they are again flocculated with ethanol, and these are separated, whereby the flocculation active material is obtained. Said flocculation active material is added under agitation into the polluted sea water on the sludge dredging site of harbors, whereby the polluted sea water is purified considerably.
