Product Description

Eliminate wastewater and reduce your energy use with a GreenFlow™ pH system. This upflow system reverses the normal flow of water through the media bed, eliminating the need for a backwash. Since the media works through the process of disolving, you still get effective treatment of low acidity water without electricity or wasted water.

Service Flows
Service flow rate is the manufacturer's recommendation for maximum neutralization of low pH at a constant flow. Intermittent flow rate and/or higher pH levels MAY allow higher treatment flow rates. In most applications intermittent flow rates of 2-3 times the rated flow rate MAY be possible.
