METHOD OF PURIFICATION OF NATURAL AND SEWAGE WATERS AND DEVICE FOR ITS REALISATION Russian patent published in 2013 - IPC C02F1/24 

FIELD: chemistry.

SUBSTANCE: invention relates to equipment for purification of natural and sewage waters and can be applied for purification from organic and inorganic contaminations at enterprises of water purification of drinking water, communal facilities and TEP. Method includes division of natural and sewage waters into purified liquid and foamed product of contaminations. To remove finely-dispersed contaminations in installation for obtaining plasmoids additionally formed are positively and negatively charged hydrated ions, which are used to saturate water by means of created by ventilator air flow, formed ionised complexes are directed into foamed product of contaminations, which is separated from purified liquid. Method is realised in device, which contains case, partition in form of truncated cone with central hole, dividing case into upper and lower chambers, overflow pipe, brought out beyond partition upward. Device additionally contains installation for obtaining plasmoids and formation of positively and negatively charged hydrated ions, which is connected with overflow pipe by means of horizontal air conduit with ventilator and contains reservoir with water, in which located are circular short-circuited copper anode and placed into quartz tube cylindrical graphite cathode, with vertical axis of cathode being perpendicular to air conduit, lower butt end of cathode is connected with conductor via electronic key and timer with negatively charged plate of condenser battery, upper butt end of cathode projects over water level, and anode is connected with positively charged plate of condenser battery via conductor, disk with through holes is immovably fixed on lower butt end of overflow pipe, and, at least, two through peripheral holes are located in partition.

EFFECT: increased degree of water purification from fine particles of contamination with size smaller than 5,0 mcm.
