Corosex F

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. Corosex, being soluble to acidity, will have to be re plen ished periodically. Please note, under certain low flow conditions, Corosex may overcorrect and create a basic condition.

Corosex can be effectively combined with Calcite to combine
the high flow neutralization properties of Corosex, along with
the slower reacting low flow properties of Calcite reducing
potentially high basic properties due to overcorrection.

Physical Properties:

Color - Grayish White
Density - 75lbs./cu. ft.
Effective Size - 1.27 mm
Uniformity Coefficient - 1.48
Active Material (%) - 84-90
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 exceeding5
     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.
