Backwashing
After the resins are exhausted, the bed is backwashed.
Backwashing is carried out by a uniform upward flow of water
through the resin bed. The backwash step expands the resin
bed releasing any entrapped particulate matter & removes the
channeling in the resin column if occurred during the
service cycle.
