Using unique processes, and thus having high mechanical strength and chemical stability, widely used in water treatment and desalination of sugar decolorizing can also be used for the refinement of organic matter and the treatment of wastewater containing chromium.

Corresponding Brands:
1． Purolite A100
2．Dowex66
3． Amberlite IRA-93
Precautions：
1． Resin should be wet state preservation. The best temperature is above 0℃. Resin should be put into a closed space or added to salt water of 5% or above if not used for a long time. Should be anti-freezing during transportation. Do not place heavy objects on the resin in the case of being crash.
2． Generally requires alkali- water - acid - water flow path for processing. The strict requirement needs three circulations before coming to the final ion kennel.
3． Need to consider different transformation expansion rates to set aside enough space to prevent resin overflow and ensure the appropriate liquid level height; Column diameter ratio should be within a reasonable range and avoid bias current; Use a wet packed column or back-flushing to wash away bubbles inside resin layer.
4． Before liquid goes into the resin column, steps such as flocculation, filtration, or sand-filtration should be taken so that it doesn’t jam the resin pores with suspended solids.
5． Resin inside the column that hasn’t been used for a long time should be stored outside of the column after washing, or adding salt water in the salt-resistant medium while keeping the liquid level not dehydrated with usual backwashing to loosen resin in case of agglomeration.
