Softening

Cation exchange resin removes hardness ions and must be sized from flow, hardness leakage and operating capacity.

Backwash, brine draw, slow rinse and fast rinse restore resin capacity when controlled correctly.

Iron, oil, suspended solids and oxidants can foul or damage resin and should be controlled upstream.
