Clack Corosex: High-Efficiency pH Correction Media for Acidic Water

Clack Corosex is a highly effective magnesium oxide media designed to neutralize acidic water conditions by correcting the pH level, making the water less corrosive. This media is particularly beneficial in applications where substantial pH correction or high flow conditions are required. With its high reactivity, Corosex offers efficient pH correction, reducing the need for large quantities of chemicals compared to alternatives like calcium carbonate.

Key Features: Superior pH Correction and Efficiency

• Highly Reactive Magnesium Oxide: Provides effective pH correction, particularly in substantial or high flow conditions.
• Neutralizes Acidic Water: By neutralizing free carbon dioxide, Corosex corrects acidic water and reduces corrosion.
• High Efficiency: Magnesium oxide in Corosex can neutralize five times more acidity per weight than calcium carbonate, leading to lower chemical usage.
• Combination Use: Can be combined with Clack Calcite to balance high flow neutralization with slower reacting low flow properties, preventing overcorrection.
• NSF/ANSI Standard 61 Certified: Ensures the media meets safety and quality standards for drinking water.

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.

Operational Conditions

• pH Range: Suitable for water pH range of 4.5-6.0.
• Service Flow Rate: 5-6 gpm/sq. ft., modifiable based on local conditions.
• Bed Depth: 24-30 inches, with a 50% freeboard of bed depth (minimum).
• Backwash Rate: 10-12 gpm/sq. ft. to prevent potential cementing.
• Gravel Support Bed: Recommended for optimal performance.
• Service Type:
  • Downflow Service: Recommended for water with hardness less than five grains per gallon or when combined 50-50 with Calcite.
  • Upflow Service: Recommended for hardness exceeding five grains per gallon to prevent cementing of the Corosex bed.
• Distributors: Use those designed for upflow applications.

Important Considerations

• Hardness Increase: As Corosex neutralizes water, it can increase hardness, necessitating the use of a water softener post-treatment.
• Overcorrection Risk: Under low flow conditions, Corosex may overcorrect, leading to highly basic water conditions. Combining with Calcite can help mitigate this risk.

Ideal Applications

• Homes and Businesses: Where water acidity is a concern and needs effective pH correction.
• Water Treatment Facilities: Ensures large volumes of water are treated efficiently with reduced chemical use.
• Industrial Applications: Where high flow and substantial pH correction are required, such as in manufacturing processes.
