IPC: B01D61/36
Filed: 1992-01-21
Abstract: PURPOSE:To obtain treated water of high purity by a method wherein the water pressure on the condensed water side of a membrane evaporative concentrator is kept higher than that on the waste fluid side thereof and the lowering of the formation amount of condensed water is detected to wash a hydrophobic porous membrane with chemicals and the washed membrane is dried to be regenerated. CONSTITUTION:A waste fluid is introduced into a tank 7 and cooling water is supplied to the cooling chamber 13 of a membrane evaporative concentrator 1 through a circulating system 3. The waste fluid in an evaporation chamber 12 has high temp. to generate evaporation and the generated steam is diffused through a hydrophobic porous membrane to be condensed in the cooling chamber 12. Therefore, the surfactant in the waste fluid is conc. on the surface of the membrane and the particles of the surfactant are settled into the membrane to make the membrane hydrophilic and the waste fluid penetrates in the membrane to become liquid flow. Since the pressure of the cooling chamber 13 is higher than that of the evaporation chamber 12 at this time, cooling water flows in the waste fluid. This inflow amount is increased by making the membrane hydrophilic and an evaporation speed decreases. A chemical agent such as hydrogen peroxide is sent to the cooling chamber 13 from a tank 9 to wash org. matter. Thereafter, a blower 10 is operated to dry the chemical solution remaining in the pores of the membrane 11 to remove the same.
