By neutralizing the free carbon dioxide in water, Corosex can correct acidic water conditions and render it less corrosive. Corosex, being a highly reactive magnesium oxide, is used most effectively where pH correction is substantial or high flow conditions are in use. pH correction and media consumption are affected by a number of water chemical variables. Being soluble to acidity, Corosex will slowly dissolve and will need to be replenished periodically. On a per weight basis, magnesium oxide can neutralize much more acidity than can calcium carbonate, (five times as much). This results in greatly reduced chemical usage for the same pH correction. Please note, under certain low flow conditions, Corosex may overcorrect and create a highly basic (high pH) condition. Under certain hardness conditions, pH correction can cause hardness minerals to precipitate out of solution, resulting in cementing or solidification of the Corosex mineral bed. Upflow service is generally recommended with hardness exceeding five grains per gallon. (Always use an in-line filter ahead of an upflow system to prevent plugging of the lower distribution screen.) As Corosex’s magnesium oxide neutralizes the water, it will increase hardness and a softener may become necessary after the neutralizing filter. Corosex can be effectively combined with Clack 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.

ADVANTAGES •High degree of activity and speed of correction allowing high flow •High capacity...less chemical usage PHYSICAL PROPERTIES Corosex •Color: Brownish white •Bulk Density: 75 lbs./cu. ft. •Mesh Size: 6 x 16 •Specific Gravity: 3.6 gm/cc •Effective Size: 1.4 mm •Uniform Coefficient: 1.7 •Composition: MgO 97% min. Corosex II •Color: White •Bulk Density: 100 lbs./cu. ft. •Mesh Size: 6 x 16 •Specific Gravity: 3.4 gm/cc •Effective Size: 1.3 mm •Uniform Coefficient: 1.5 •Composition: MgO 99% min. CONDITIONS FOR OPERATION •Downflow service is generally satisfactory on waters with a hardness of less than five grains/gal. or where it’s combined with Calcite at least 50-50. Upflow service is generally recommended with hardness exceeding five grains/gal. to prevent “cementing of the Corosex bed” •Use distributors designed for upflow applications •A gravel support bed is recommended •Water pH range: 4.5-6.0 •Bed depth: 24-30 in. •Freeboard: 50% of bed depth (min.) •Backwash frequently to prevent possible cementing •Backwash rate: 10-12 gpm/sq. ft. •Service flow rate: 5-6 gpm/sq. ft. but may be modified to adapt to local conditions

Calcite is a naturally occurring calcium carbonate media. One of the advantages of Calcite is its self-limiting property. When properly applied, it corrects pH only enough to reach a non-corrosive equilibrium. It does not overcorrect under normal conditions. Upon contact with Calcite, acidic waters slowly dissolve the calcium carbonate to raise the pH which reduces the potential leaching of copper, lead and other metals found in typical plumbing systems. Periodic backwashing will prevent packing, reclassify the bed and maintain high service rates. Depending on pH, water chemistry and service flow, the Calcite bed will have to be periodically replenished as the Calcite is depleted. ADVANTAGES •Naturally occurring material •Low uniformity coefficient for maximum contact for controlled pH correction •Slower reacting for controlled pH correction •Inexpensive PHYSICAL PROPERTIES •Color: Near white •Bulk Density: 90 lbs./cu. ft. •Mesh Size: 16 x 40 •Specific Gravity: 2.7 •Effective Size: 0.4 mm •Uniformity Coefficient: 1.5 •Hardness: 3.0 (Mohs scale) •Composition: CaCO3, 95% min. MgCO3, 3.0% max. CONDITIONS FOR OPERATION •A gravel support bed is 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 As the Calcite’s calcium carbonate neutralizes the water, it will increase hardness and a softener may become necessary after the neutralizing filter. Calcite can be effectively combined with Clack Corosex to combine the high flow neutralization properties of Corosex, along with the slower reacting low flow properties of Calcite, increasing the ability to correct low pH.
