METHOD FOR PURIFYING WATER FOR ECONOMY AND DRINKING WATER SUPPLYING AND APPARATUS FOR EFFECTUATING THE SAME Russian patent published in 2006 - IPC C02F1/74 B01F3/04 

FIELD: purification of ground water from iron, manganese, copper and other metals and simultaneously removal of hydrogen sulfide and other hazardous gases, in particular, supplying of cities, populated localities, individual objects and agricultural complexes with water.

SUBSTANCE: method involves vacuumizing and mixing water stream to be purified with air by dispersing water with air; feeding water-and-air mixture into casing containing non-immersed filtering charge; providing separate discharge of purified liquid stream and air; performing vacuumizing process by feeding liquid stream under pressure into converging tube equipped with Venturi nozzles; separating stream in converging tube and directing through Venturi nozzles; continuously ejecting air from environment and performing filtering of purified water during free flowing thereof. Mixer with air sucking apertures is positioned concentrically at the outer side of converging tube. Outer part of converging tube surface is defined by uniting side surfaces of a number of truncated cones whose bases are extending in two parallel planes, and centers of these bases are apexes of regular polygons.

EFFECT: increased efficiency in removal from water under purification process of inorganic difficult-to-oxidize substances and organic substances, and reduced number of purification steps.
