001*7 Cation Exchange Resin, Strong Acidic Adsorption Resin for Softening Industrial Water Quality

Primary Function: Water Softening

Its main purpose is to remove hardness ions, specifically calcium (Ca²⁺) and magnesium (Mg²⁺) from water.

Working Principle: Ion Exchange

The resin contains sulfonic acid groups (-SO³H) and is initially saturated with sodium ions (Na⁺).

Exchange Process: When hard water passes through, the resin swaps its sodium ions (Na⁺) for the calcium (Ca²⁺) and magnesium (Mg²⁺) ions in the water.

2R-SO³Na + Ca²⁺ → (R-SO³)₂Ca + 2Na⁺

Regeneration: Once exhausted, the resin is regenerated with a concentrated brine (NaCl) solution, which reverses the process, releasing the hardness ions as waste and reloading the resin with sodium ions.

Key Benefits in Industrial Applications

Prevents Scale Formation: Eliminates hard scale in boilers, heat exchangers, and cooling systems.

Improves Efficiency: Reduces fuel and energy consumption by maintaining heat transfer efficiency.

Protects Equipment: Extends the lifespan of industrial machinery and piping.

RO Pretreatment: Protects reverse osmosis membranes from scaling.

Other Functions

Deionization: When used in H⁺ form with an anion resin, it produces demineralized water.

Heavy Metal Removal: Can adsorb heavy metal cations like copper and lead from wastewater.
