Understanding the Backwash Cycle in Water Softener
Backwash
Although the product continuously cleans itself as a normal part of the process, a backwash step is part of the system where the media in the tank is physically lifted up, spun around and agitated under pressure. The agitation and spinning cleans it of any particles such as dirt, clay and iron which has been filtered out during normal use of the system. The backwash water containing the undesirable particles flow harmlessly to drain.
