METHOD FOR REGENERATING IONIC EXCHANGE RESINS USED FOR SOFTENING WATER AND DEVICE FOR SOFTENING WATER

摘要

A method for regenerating ionic exchange resins (3) used for softening waterand a device for softening water. A flow of brine (S) is fed into a housingcompartment (2) of the resins (3) at a determined velocity and subsequently afirst flow of water alone is fed at a lower velocity than the velocity of theflow of brine (S). Said velocities are determined by a ratio between thepassage section of a respective throat (8) for feeding the water, and thepassage section of a nozzle (10) for feeding the brine (S).
