Why should the new resin be disposed of? How do we deal with it?
Specific treatment methods include:(1) treated with salt water;Salt water solution 10%, approximately equal to the volume of resin treated 2 times to soak for 20 hours or more, and then put salt water, with water rinse, drain water with yellow. If the impurities and fine resin powder should be rinsed clean.(2) treated with dilute hydrochloric acidWith 2%, a 5% concentration of HCl solution, about equal to 2 times the volume of resin treated, soaked for more than 4 hours, and then put the acid solution, washed with water until neutral.(3) treated with dilute sodium hydroxide solution, with 4% NaOH solution, approximately equal to 2 times the volume of resin treated, soaked for 4 hours, and then put lye, washed with water until neutral.
The above treatment, such as the use of 3m / h flow rate of flow treatment, the effect will be better. After the new resin has been treated, the stability will be improved remarkably.
The new ion exchange resin, because often contain a small amount of low polymer and end in polymerization material, in addition to the organic matter, usually contains iron, aluminum, copper and other inorganic substances; therefore, when in contact with water, acid, alkali resin or other solution, the soluble impurities will be transferred to the solution and influence water quality. Therefore, the new resin should be treated before use.
