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 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.

“The water quality, filter cycle, savings projections and ease of operation are beyond our expectations.
