THE MANUFACTURING METHOD OF OPEN POROUS FILTER MATERIAL MADE BY SPECIAL FOAMING PROCESS FOR WATER TREATMENT SYSTEM USING OZONIZATION MEANS AND THEREFOR THE OPEN POROUS SPECIAL FILTER MATERIALS FOR WATER TREATMENT

摘要

The water treatment filter material according to the present invention is prepared by mixing a mixture of silicon dioxide (SiO ₂ ) and aluminum oxide (Al ₂ O ₃ ) having a particle size of 10 to 60 μm in a mass ratio of 1: 1 to 3: 1, A sodium-based aqueous solution is mixed in an amount of 70 to 100% by mass to prepare a thick liquid mixture, and then a silicon-based stabilizer and an anion-based activator each in an amount of 0.1 to 0.5% with respect to the mass are further mixed to complete a liquid mixture And then pouring the liquid mixture into a mold having a diameter of 20 to 50 mm and then irradiating the microwave to foam at 200 to 250 ° C. for 1 to 3 minutes and then drying the porous material for water treatment . Thus, the present invention provides an open porous water-treated filter material that absorbs and permeates moisture, which is significantly improved in environmental friendliness and economical efficiency, while remarkably improving the adsorption performance of ozone oxides present in wastewater.
