About Calcite for pH correction in water Calcium Carbonate
Acidic waters on contact with Calcite slowly dissolve the calcium carbonate media to raise the pH which reduces the potential leaching of cooper, lead and other metals found in typical plumbing and maintain high service rates. Depending on pH and Service flow, the Calcite bed will have to be periodically added to as the dissolved calcite depletes.
As the Calcite's calcium carbonate neutralizes the water, it will increase hardness and softener may become necessary after the neutralizing filter.
Advantages: High uniformity coefficient for maximum contact for controlled pH correction Slower Reacting Inexpensive
Physical Properties: Color - Near White Density - 100 lbs./cu. ft. Composition - CaCO3. 95% minimum MgCO3, 3.0% maximum
Bed Depth - 24 - 30 in. Backwash Rate - 8-12 gpm. Sq. ft.
Backwash Bed Expansion - 35% of bed depth Service Flow Rate - 3.6 gpm/sq. ft. invariably give satisfactory results but may be modified in view of local conditions
