Features Of Purolite A 500 Plus Ion Exchange Resin

  1. Highly selective for nitrate and perchlorate removal from drinking water and process streams.

  2. Superior kinetic performance due to uniform macroporous bead structure and optimized surface area.

  3. Exceptional chemical and physical stability in chloride-rich environments, minimizing degradation during regeneration.

  4. Low operating pressure drop and excellent hydraulic flow characteristics for high-throughput systems.

  5. Regenerable with common brine solutions, supporting sustainable and cost-effective long-term operation.

Typical Applications Of Purolite A 500 Plus Ion Exchange Resin

  1. Drinking water treatment for selective nitrate and perchlorate reduction to meet regulatory standards.

  2. Pharmaceutical process water polishing where low ionic leaching and high purity are critical.

  3. Food and beverage production water conditioning for consistent ion profile control.

  4. Electronics manufacturing ultrapure water pre-treatment targeting trace anion removal.

  5. Municipal and industrial wastewater tertiary treatment for targeted anion recovery or discharge compliance.
