Choosing the Right Water Softening Resin: A Guide to Cation Exchange Resins
Hard water can wreak havoc on your industrial processes, domestic pipelines, and reverse osmosis systems. From scale formation to reduced equipment life, calcium and magnesium ions are the silent culp
💡 How Water Softening Works
Water softening is the process of removing calcium (Ca²⁺) and magnesium (Mg²⁺) ions from water. These ions cause scaling and reduce the efficiency of boilers, cooling towers, and process equipment.
Strong acid cation (SAC) resins in sodium (Na⁺) form are used for this. They work by exchanging sodium ions with hardness ions:
2R-Na + Ca²⁺ → R₂-Ca + 2Na⁺
This exchange continues until the resin is exhausted and then regenerated using common salt (NaCl).

⚙️ Sizing Your Resin Bed
When choosing a resin, consider:
- Feed water hardness (ppm)
- Desired treated water volume per regeneration (OBR)
- Regeneration salt usage
- Bed depth and flow velocity
Our technical team can help calculate your required resin quantity (in liters), flow rate (m³/hr), and regeneration frequency.

💬 Frequently Asked Questions
Q: How often should I regenerate my softener resin?
A: Depends on hardness level and flow rate. On average, softeners are regenerated after 4–8 m³ per liter of resin.
Q: Can ASHAION® resins be used in both domestic and industrial setups?
A: Yes. We have grades like C-200 Na for homes and C-250 Na/C-270 Na for industries.
Q: What is the typical shelf life of ASHAION® softening resin?
A: 2–3 years if stored in sealed bags in a cool, dry place.
