Intermittent flow rate and/or lower contaminant levels MAY allow higher treatment flow rates. Backwash Flow Rates The backwash flow rate is the minimum rate that MUST be available to ensure proper backwashing and adequate media life. While lower flows can be used and MAY provide adequate results, media life may be significantly reduced.
