ResinTech SIR-700-HP is an acid salt form granular gel weak base anion resin. The HP designation means it is Gold Seal Certified by the WQA for use in potable water applications. Its unique functionality utilizes a secondary mechanism for chromate removal that causes chromium to precipitate inside the resin matrix when the feed pH is slightly acidic. SIR-700-HP is intended for all chromate removal applications.
