FIELD: ecology; multi-stage methods of cleaning and decontamination of portable water; final cleaning and conditioning of tap water.
SUBSTANCE: proposed method includes preliminary filtration of water at first stage of micro-filtration through porous filter element made in form of tube from porous titanium or radiation-modified porous polyethylene at size of pores from 1 to 5 mcm in direction perpendicular to water flow; part of treated water is periodically discharged for use; after preliminary filtration, water flow rate is averaged to 15-20 l/h, after which is treated with ions of decontaminant; silver is used as contaminant; procedure is continued till concentration of silver reaches 0.1-0.0025 mg/l; second stage of micro-filtration is effected by means of porous filter element made from ceramics or cermet at size of popers of 0.2-0.4 mcm and then water is subjected to degassing.
EFFECT: low cost of process; possibility of performing ecologically pure technology of cleaning water.
