Corosex / Flomag media for pH adjustment in water Magnesium Oxide
By neutralizing the free carbon dioxide in water, Corosex / Flomag can correct red water conditions and render it to a non-corrosive condition. Corosex / Flomag, being a reactive magnesium oxide, is used most effectively where pH correction is substantial or high flow conditions are in use. Corosex / Flomag, being soluble to acidity, will have to be replenished periodically. Please note, Under certain low flow conditions, corasex may overcorrect and create a basic condition.
Corosex can be effectively combined with Calcite to combine the high flow neutralization properties of Corosex / Flomag, along with the slower reacting low flow properties of Calcite reducing potentially high basic properties due to overcorrection
High degree of activity and speed of correction allowing high flow
Color - Grayish White
Density - 100 lbs./cu. ft.
Effective Size - 1.27 mm
Uniformity Coefficient - 1.48
Active Material (%) - 84.90
Composition - MgO - 97% minimum
Conditions For Operation:
Downflow service is satisfactory on waters with a hardness of less than five (5) gr./gal. Or where it's combined with Calcite at least 70% calcite. Upflow service is generally recommended with hardness exceeding five (5) gr./gal. To prevent 'cementing of the mineral bed'
A gravel support bed is recommended.
pH - 4.6
Bed Depth - 24-30 in.
Backwash frequently to prevent possible cementing.
Backwash Bed Expansion - 35% of bed depth
Service Rate - 5-6 gpm./sq. ft. but may be modified to adapt to local conditions
