IPW Industries Inc (1317-65-3) Calcite - Neutralizes Low pH or Acidic Water - 1 Lb.
Calcite pH Neutralizing Media (1317-65-3)
Calcite dissolves slowly in acidic water to raise pH and reduce metal leaching from pipes. Its self-limiting chemistry stops at a non-corrosive equilibrium, preventing the overcorrection common with other neutralizing media.
Controlled pH Correction Through Dissolution
Acidic Water Entry
Low pH water (5.0-7.0) enters the calcite bed at 3-6 gpm per square foot. The 16x40 mesh size and 1.5 uniformity coefficient ensure consistent contact time without channeling.
Calcium Carbonate Release
The acidic water slowly dissolves calcium carbonate from the calcite media. This controlled reaction raises pH gradually, preventing the alkaline spikes that damage plumbing and taste.
Self-Limiting Correction
As pH rises to non-corrosive levels, dissolution slows and stops naturally. Backwash at 8-12 gpm per square foot every few weeks to reclassify the bed and prevent packing.
Physical Properties
| Composition | CaCO₃ 95% min., MgCO₃ 3% max. |
| Mesh Size | 16 x 40 |
| Effective Size | 0.4 mm |
| Uniformity Coefficient | 1.5 |
| Bulk Density | 90 lbs./cu. ft. |
| Specific Gravity | 2.7 |
| Hardness | 3.0 Mohs |
| Color | Near white |
Installation Requirements
| Water pH Range | 5.0 - 7.0 |
| Bed Depth | 24 - 30 inches |
| Freeboard | 50% of bed depth (minimum) |
| Service Flow Rate | 3 - 6 gpm/sq. ft. |
| Backwash Rate | 8 - 12 gpm/sq. ft. |
| Backwash Expansion | 35% of bed depth |
| Gravel Support | Recommended |
System Considerations
The IPW Industries 1317-65-3 calcite media requires a properly sized neutralizing tank with gravel underbed support and adequate freeboard for backwashing. As the calcium carbonate neutralizes acidic water, it increases hardness levels, so plan for a water softener downstream if your source water already contains moderate hardness. Calcite depletes over time based on influent pH and flow rates, so periodic media replenishment is part of normal operation. This 1 lb. package is suitable for topping off existing beds or testing small-scale applications before committing to bulk quantities.
