SP217 Strong Basic Gel-Type Anion Resin

A strongly basic, gel-type anion exchanger which is highly regenerated and specially cleaned. Depending on the high operating capacity for one-use applications and the high chemical and mechanical stability.

SP217 is especially applicable to mixed bed systems together with SP 117 for the decontamination of cooling circuits in power stations and as a polishing step after EDI systems in the production of ultrapure water.
