Backwashing pH Neutralizer

Calcite is a crushed and screened white marble media which can inexpensively be used to neutralize acidic or low pH waters to a neutral, less corrosive output. Calcite corrects pH only enough to reach a non-corrosive equilibrium. Certified to NSF/ANSI Standard 60 Periodic backwashing will prevent packing, reclassify the bed and maintain high service rates. Depending on pH, water chemistry and service flow, the Calcite bed will have to be periodically replenished as the Calcite is depleted. Low uniformity coefficient for maximum contact for controlled pH correction. Inexpensive media. Water pH range of 5.0-7.0. Service flow rate of 6 gpm/sq ft (Intermittently higher flows possible). Backwash flow rate of 12 gpm/sq ft

*** Important! - To ensure the proper operation of your neutralizing filter, be sure that when sizing the system your well pump can deliver at least 20% more water than the backwash requirement of your intended system. As the Calcites calcium carbonate neutralizes the water, it will increase hardness and a softener may become necessary after the neutralizing filter.
