6、 Precautions:

1．Resin should be wet state preservation. The best temperature is above 0℃. 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.

2．Generally requires alkali- water - acid - water flow path for processing. Strict requirement needs three circulation before coming to final ion kenel.

3．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.

4．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 .

5．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.

Strong Acid Cation Resin 001x7 Na

The ion exchange method is used to deeply treat the wastewater generated in the nickel-cobalt wet smelting system, so that the wastewater can achieve the purpose of recycling and reduce the waste of water resources. The results show that Purolite S960 ion exchange resin is used to treat production wastewater containing nickel (0.52g/L), cobalt (0.60g/L), and manganese (0.45g/L), and its saturated adsorption capacity is 112.9g/L wet resin. After treatment, the content of each metal in the wastewater can be reduced to 0.1mg/L, which is far below the limit of the emission standard; the separation and enrichment of valuable metals can be achieved by using the segmented elution method; the resin has good regeneration performance and is saturated The elution rate of each metal in the resin is greater than 98%, which can meet the needs of production. 001-7, 001*7, 001x7 sodium type resin; 001x7 strong acid resin rare element separation resin; pollutants in tanning wastewater are mainly composed of chromium ions, dyes, organic matter and inorganic salts, and their COD and BOD are high, so it is treated The difficulty is greater. The adsorption method to treat tannery wastewater is a new method of tannery wastewater that has developed rapidly in recent years.

001×7Na is a gel-type strong acid cation exchange resin with a polystyrene skeleton, containing sulfonic acid groups, which is equivalent to solid sulfuric acid. Mainly used in the water treatment industry. And the strong acid cation exchange resin adsorbs Ni2 with higher selectivity.

001x7 strong acid cation resin has high mechanical strength and fast exchange speed; the demand for ion exchange resin in the water treatment field is very large, accounting for about 90% of the output of ion exchange resin, used for the removal of various anions and cations in water. At present, the largest consumption of ion exchange resin is used in pure water treatment in thermal power plants, followed by atomic energy, semiconductors, and electronics industries.

Ion exchange resins in the food industry can be used in industrial devices such as sugar, monosodium glutamate, wine refining, and biological products. For example, the manufacture of high-fructose syrup is to extract starch from corn, and then undergo hydrolysis to generate glucose and fructose, and then undergo ion exchange treatment to produce high-fructose syrup. Ion exchange resin was used to soften the simulated metallurgical wastewater, and the effects of resin types, wastewater salt content, and inorganic salt types on the wastewater softening effect were investigated.
