Clack (Imerys) Calcite Neutralization Media: Effective pH Correction for Acidic Water
Clack (Imerys) Calcite Neutralization Media is a crushed and screened white marble media designed to neutralize acidic or low pH water, making it less corrosive. Calcite, a naturally occurring calcium carbonate, is an economical and effective solution for pH correction. Its self-limiting property ensures that it only raises the pH enough to reach a non-corrosive equilibrium, preventing over-correction under normal conditions.
Key Features: Reliable and Economical pH Correction
- Naturally Occurring Calcium Carbonate: Calcite is a natural and cost-effective media for pH correction.
- Self-Limiting Property: Corrects pH just enough to reach a non-corrosive level, preventing over-correction.
- Prevents Metal Leaching: Raises pH to reduce the leaching of copper, lead, and other metals in plumbing systems.
- Periodic Backwashing: Maintains high service rates and prevents packing by reclassifying the bed.
- Combination Use: Can be combined with Clack Corosex for enhanced neutralization, balancing high flow with slower reacting properties.
- Certified: Meets NSF/ANSI Standard 60, ensuring safety and quality for drinking water.

Operational Conditions
- pH Range: Effective in water with a pH range of 5.0-7.0.
- Bed Depth: Recommended 24-30 inches.
- Freeboard: Minimum 50% of bed depth.
- Backwash Rate: 8-12 gpm/sq. ft. to ensure optimal performance and prevent bed compaction.
- Backwash Bed Expansion: 35% of bed depth to maintain effectiveness.
- Service Flow Rate: 3-6 gpm/sq. ft., adjustable to local conditions.
Important Considerations
- Periodic Replenishment: The Calcite bed will need to be replenished periodically as it is consumed in the pH correction process.
- Increase in Hardness: As the water is neutralized, hardness may increase, necessitating the use of a water softener after the neutralizing filter.
- Gravel Support Bed: Recommended for optimal performance and bed stability.
Ideal Applications
- Residential and Commercial Water Systems: Effective for neutralizing acidic water to protect plumbing and improve water quality.
- Industrial Applications: Ideal for use in systems where maintaining non-corrosive water is essential.
- Combination with Corosex: Enhances the pH correction process, especially in systems requiring both high flow and slow reacting properties.
