The backwash flow rate is regulated to expand the bed by 50 to 100% of it service volume. If the backwash rate is ,too high,, however, some of the resin will be washed out of the vessel along with the dirt and debris. If the backwash water temperature changes, the flow rate must be adjusted to prevent this from occurring.
