It is primarily used for industrial desalination and the adsorption of cyanide pulp in hydrometallurgical processes.
Resin should be kept in a wet state, stored above 0℃. For long-term storage, keep it in a closed space or add a 5% or higher salt water solution.
The recommended regeneration process involves using 2BV of 3~5% HCl and 2BV of 2~4% NaOH.
Yes, D201 SC is designed as a high-performance equivalent to Amberlite 200, Lewatit SP-210, and Diaion PA308.
Steps like flocculation or sand-filtration prevent suspended solids from jamming the resin pores, which would otherwise reduce efficiency and lifespan.
The Macroporous Strong Basic Anion Exchange Resin D201 SC can operate at temperatures up to 120℃.
