Ion Exchange Resin

Product Description

1,How to store it:

It can be kept in the air, the temperature should be 0-40degree centigrade; if the temperature is below zero, add clear saturated salt water into packing bag to immerse resin; the high temperature can dehydrate and degrade the resin; one the resin has lost its moisture, it should be immersed in saturated salt water first, and then diluted it and wash the salt away. The resin should be in wet condition during storage.

2, How to handle it:

Washing the new resin with hot water in several tiome before stuffed, cation exchange resin uses 70-80degree centigrade of water, anion exchange resin is about 50-60degree centigrade; At beginning, change the water every 15 minutes, no stirred it, after 4 to 5 times of water change; the change time is 30min every time, the resin should be immersed in 7 to 8 times until the water is not brown any more and with less foam; after washing, you can handle it with acid and alkali. For cation exchange resin: 1, flow the resin with N HCl, the dosage is 2 to 3 times of strong acid cation resin, 3 to 5 times of weak acid resin, 1.5 times of bead every hour; , washing it, the PH is about 5, flow the resin with 3 times of resin volume of 5% NAcll solution, the flow rate just like step 1; 3, flow the resin with 1N NaOH, the flow rate just like step 1; 4, washing it untill the PH of outlet water is 9; 5, washing it with 1N HCL or H2SO4, change the resin into H type, the dosage is 2 to time of resin volume, the flow rate just like step 1; 6, after acid washing, washing it with deionized water until PH of outlet water is 6; and then it can be used. for anion exchange resin , after washing, it can be washed in alkali-acid-alkali, the dosage and flow rate, Strong alkali resin is relative to Strong acid resin

3, regeneration treatment:

Once the resin is put into function, its exchange capacity may get reduced after certain time, the water quality in outlet became worse and worse; these phenomena are caused by pollution of resin; during the extraction of sewage and biochemicals, whose ingredients are very complex, then the resin is eaay to be polluted, so the resin beed to be regenerated in different methods according to different condition. We can provide technical support for you
Macropore resin should be immersed in acetone and methanol, the dosage is 3 to 5 times of resin, the he flow rate just like step 2-(1)
