MICROFILTERING APPARATUS OF WATER PREPARATION Russian patent published in 1996 - IPC

FIELD: water preparation with usage of microfiltering in conjunction with ultrasonic and oligodynamic treatment after removal of dissolved impurities by selection bacteria adapted to different types of impurities. SUBSTANCE: water is purified microbiologically in biofilter by aerobic microorganisms during its successive passing from previous section into following section by overflowing pipes and by its blowing through by air from bubblers in presence of immobilizing tip made in the form of flexible threads. Microorganisms separation is exercised in apparatus during microfiltering with water treatment with ultrasound generated by rotation of lower disk. Simultaneously oligodynamic treatment of water is exercised with metals and their alloys (copper, silver etc). The successive treatment of water decreases costs of water preparation by 19 - 20 times. EFFECT: improved water purification quality and decreased significantly costs of the water preparation. 3 dwg
