Aqua Pure Water Filters

1/2 Cubic Foot For highly acidic conditions. Corosex F can be mixed with Calcite to treat waters as low as 4.0Ph. Upflow filters are recommended unless the water is under 5 grains hard. A minimum of 50% Calcite is recommended to prevent cementing. By neutralizing the free carbon dioxide in water, Corosex can correct red water conditions and render it to a non-corrosive condition. Corosex, being a reactive magnesium oxide, is used most effectively where pH correction is substantial or high flow conditions are in use. Physical Properties:
l Color - Grayish White
l Density - 75lbs./cu. ft.
l Effective Size - 1.27 mm
l Uniformity Coefficient - 1.48
l Active Material (%) - 84-90
l Composition - MgO - 97% minimum
Conditions for Operation:
1. Downflow service is satisfactory on waters with a hardness of less than 5 gr./gal. or where it's combined with Calcite at least 50-50. Upflow service is generally recommended with hardness exceeding 5 gr./gal. to prevent "cementing of the mineral bed."
2. A gravel support bed is recommended.
3. pH - 4-6
4. Bed Depth - 24-30 in.
5. Backwash frequently to prevent possible cementing.
6. Backwash Bed Expansion - 35% of bed depth.
7. Service Rate - 5-6 gpm/sq. ft.,but may be modified to
adapt to local conditions.
8. Backwash Rate - 8-12 gpm/sq. ft.
