Features Of Purolite Supergel SGC 650 Na Ion Exchange Resin

  1. High-capacity, macroporous gel-type strong acid cation exchange resin in sodium form.

  2. Exceptional physical and osmotic stability for extended service life under cyclic loading and regeneration.

  3. Optimized bead uniformity and narrow particle size distribution (U.S. Sieve No. 16–50) for low pressure drop and efficient mass transfer.

  4. Low fines generation and high mechanical strength, minimizing resin loss during backwashing and service.

  5. Designed for reliable performance in demanding softening and demineralization applications with high flow rates.

Typical Applications Of Purolite Supergel SGC 650 Na Ion Exchange Resin

  1. Industrial boiler feedwater softening to prevent scale formation and ensure steam purity.

  2. Food & beverage processing water conditioning for consistent product quality and regulatory compliance.

  3. Pharmaceutical-grade purified water (PW) pretreatment in multi-step purification systems.

  4. Municipal and commercial cold-process water softening for laundry, hospitality, and HVAC systems.

  5. Pretreatment for reverse osmosis (RO) and electrodeionization (EDI) systems to protect downstream membranes and modules.
