Defender® Regenerative Media Filters
Defender® Water Savings
(visit for more information)
The Defender® filter virtually eliminates the tremendous amount of backwash water associated with sand filter operation. Instead of reverse flushing, as with a sand filter, Defender® simply discharges the spent media directly to waste and is recharged from time to time.
The following chart illustrates the Backwash Water Consumption of a typical indoor waterpark attraction with a 2000 GPM (454 m3/ hr) recirculation rate.
The annual water savings in excess of 2.2 million gallons (8328 m3) is complemented by associated costs related to sewer expenses, chemicals, heating, power and labor.
