Product Description

 

D301

D301 is polystyrene skeleton macroreticular weakly basic anion exchange resin, containing the

-n (CH3) ₂, weak alkaline resin in alkali type, easy to regenerate, working exchange capacity is

3 times of alkali type, nai organic pollution.Using unique and processes, and thus has 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.

Precautions

• Resin should be wet state preservation. The best temperature is above 0ºC. Resin should be put into a closed space or add in 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 case being crashed.
• Generally requires alkali- water - acid - water flow path for processing. Strict requirement needs three circulation before coming to final ion kenel.
• Need to consider different transformation expansion rate 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 wet packed column or back-flushing to wash away bubbles inside resin layer.
• Before liquid going into the resin column, steps as flocculation, filtration, or sand-filtration should be taken so that it doesn't jam resin pore with suspended solids .
• Resin inside the column that hasn't been used for a long time should be storaged outside of the column after washing, or adding salt water in the salt resistant medium while keeping liquid level not dehydrated with usual backwashing to loosen resin in case of agglomeration.
