Floating Bed Backflushing Demineralization System
Gel Strong Basic Styrene-Based Anion Exchange Resin
201X7FB, aka 717FB, is a premium grade gel-structured strong-basic styrene-based anion exchange resin of the type I functional group which contains quaternary amine, synthesized by special technology. Characterized by its high ratio of whole beads, excellent regeneration efficiency as well as good rinse performance against mechanical and osmotic impact, this resin is optimally specialized in removing both the 'strong and weak' acids anions from minerals within wastewater or raw water.
For its extra fine selectivity and high exchange capacity, 201X7FB model is primarily placed within the anion-bed, following the cation-bed filled with 001X7FB where raw water passes through first. Such two ion-exchange columns are placed in parallel by raw water reverse flowing into so as to form a composite floating bed backflushing water-processing system within various industries for precise demineralization, pure-water &ultrapure water preparation, wastewater treatment such as the separation of anionic metallic complexes, heavy-metal pollutants, organic toxicants, inorganic minerals, etc.
