FIELD: water treatment.
SUBSTANCE: in deep water desalting system installed upstream of chemical desalting unit on clarified water line, H-Na cationite filter and/or Cl anionite filter, or H-Na-Cl ionite filter are additionally included. Spent regeneration solution line of H cationite filter of chemical desalting unit is linked to H-Na cationite filter or to H-Na-Cl ionite filter and spent solution line of OH anionite filter is linked to Cl anionite or H-Na-Cl ionite filter.
EFFECT: reduced specific consumption of acid on regeneration of H filters, prevented pollution of countercurrent H cationite and OH anionite filters, reduced number or eliminated chemical treatments of ion-exchange resins, and reduced consumption of water on own needs of installation.
