<p><P>PROBLEM TO BE SOLVED: To provide a technology for reducing the biomass of algae including toxic water blooms (toxic algae), and for controlling the concentration of phosphorus in water, because nutrient salts such as phosphorus in industrial wastewater and agricultural/livestock wastewater accelerate eutrophication of aquatic environments as typified by seas, rivers, lakes, reservoirs, etc., and thus the massive proliferation phenomenon of blue-green algae (so-called water blooms) caused by the eutrophication occurs in water sources around the world and has become a serious environmental problem. <P>SOLUTION: A vibration-wave generator controls the growth of the toxic water blooms. Furthermore, an oxygen/ozone generator suppresses the elution of phosphorus which is regarded as necessary for the growth of phytoplankton (algae), from bottom mud, and promotes the adsorption of phosphorus to the bottom mud. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
