Calcite pH Water Neutralizer Media

Calcite is a crushed and screened white marble media that can inexpensively neutralize acidic or low pH waters to a neutral, less corrosive effluent. Calcite is a naturally occurring calcium carbonate media. Its self-limiting property makes it an ideal candidate for reducing the potential leaching of copper, lead, and other metals in typical plumbing systems.   Benefits: Naturally occurring material Low uniformity coefficient for maximum contact for controlled pH correction Slower reacting for controlled pH correction Inexpensive NSF Certified   Conditions for Operation: Gravel support bed (recommended) Water pH range: 5.0-7.0 Bed depth: 24-30 in. Freeboard: 50% of bed depth (min.) Backwash rate: 8-12 gpm/sq. ft. Backwash Bed Expansion: 35% of bed depth Service flow rate: 3-6 gpm/sq. ft. but may be modified to adapt to local conditions Click here for Detailed Calcite Media Specifications Periodic backwashing prevents packing, reclassifies the bed, and maintains high service rates. Depending on pH, water chemistry, and service flow, periodically replenishing the media bed as the media depletes. As the Calcite's calcium carbonate neutralizes the water, it will increase hardness, and a softener may become necessary after the neutralizing filter.
