TECHNOLOGY
OF THOROUGH PURIFICATION OF UNDERGROUND WATER
 FIELD:
processes of purification of underground water for drinking and public water
supply systems.
SUBSTANCE: proposed technology deals with methods
of purification of underground water from iron, manganese and hard salts in
particular. It can be used to win desalted water for preparation of electrolyte
for storage batteries. Technology of thorough purification of underground water
includes stage of successive mechanical filtration, Na zeolyte softening with
regeneration of cationic exchanger by 5-7% solution of sodium chloride and
electrodialysis demineralization. Before stage of mechanical filtration water is
subjected to aeration. Mechanical filtration is carried out in pressure filter
filled with inert material. Quartz sand, quartzite, albite, granodiorite,
scorched rock and so on are used in the capacity of inert material. At stage of
electrodialysis demineralization proportion of flows of diluent Q d and
brine Q b is ( 3-5 ):1.
EFFECT: optimal technology of purification of
bicarbonate underground water in combination with method of electrodialysis
demineralization. 1 cl, 1 dwg, 2 tbl
