Installer Manual Evolio 255 - Description Description 3.1. Introduction to softeners 3.1.1. Softening principles Softening is an ion exchange process where the hard ions are getting exchange by soft ions, typically sodium or potassium. This is achieved by placing the water in contact with an ion exchange resin and ensuring the contact time is appropriate for the flow rate to produce.
Page 15
Installer Manual Evolio 255 - Description The service and regeneration reaction can be done over and over, so softening systems last years. A softener consists of different components: • a tank, filled with softening resin; • a valve, that will direct the inlet water flow on the resin bed so that the softening or regeneration reaction can take place;...
Installer Manual Evolio 255 - Description 3.1.2. System service & regeneration cycles (7-cycles operation) Service — cycle C0 Untreated water is directed down through the resin bed and up through the riser tube. The hardness ions attach themselves to the resin and are removed from the raw water being exchanged on the resin beads towards sodium ions.
