Title: Treatment of suspension water
Inventor: SANO KAZUO
IPC: B01D35/027
Filed: 1986-08-27
Abstract: PURPOSE:To enable easy removal of phytoplanktons, etc., by providing filter layers to which bacteria are likely to stick into a suspension water and generating the circulating flow passing the filter layers. CONSTITUTION:The curculating flow F passing the filter layers 1 which are installed in the water and consisting of sticking substrates made of a synthetic resin having high voids and large specific surface area per volume is generated to said filter layers by a flow inducing device (e.g., underwater mixer 2, aerator 3) provided to the inside or on the outside of said filter layers. The underwater bacteria and soil bacteria, etc., suspended in the water stick to the surface of the above-mentioned substrates to form biological membrans of bacteria, etc. The filter layers 1 act to adsorb and remove the phytoplanktons when the water contg. the phytoplanktons, etc., is filtered in the filter layers 1 consisting of said sticking substrates. The suspension water is thereby easily cleaned.
