FIELD: technology of water and air purification.
SUBSTANCE: invention relates to the technology of producing deeply desalinated water and can be used in various industries. Method includes preliminary desalination by reverse osmosis to obtain concentrate and permeate, decarbonisation and deep desalination on an OH-anionite filter with a strongly basic anionite and an H-cationite filter with a strongly acidic cationite. Decarbonisation is carried out at the stage of preliminary desalination in the drain channel of the reverse osmosis roll element with application of vacuum of 0.15–0.85 bar per permeate line. Gas is then separated from permeate in a separator.
EFFECT: reduced consumption of reagents for regeneration of resins at the stage of deep desalination by removal of carbon dioxide from water after the stage of preliminary desalination.
