FIELD: technological processes; chemistry.
SUBSTANCE: method consists in water softening by its alkalisation in the first container at partial pressure of carbonic acid gas that exceeds the equilibrium pressure, crystallisation of calcium and magnesium salts in the second container at sharp drop of pressure in the presence of caproic fibers, at that regeneration of filter from caproic fibers is realised by means of their periodic shaking and flushing of processed water through nozzle of deposit discharge.
EFFECT: higher extent of water hardness reduction, higher quality of caproic cloth filter regeneration.
