1) Users of ultra-pure water systems are generally very high on water quality, and the water resistance of EDI systems is generally above 15 Megaohms when the water is discharged at first. However, some users in the electronics industry hope to get higher water quality (for example, above 18 megaohms), so it is necessary to add polished mixed-bed resin after EDI to improve the effluent quality. Therefore, in practical use, polished mixed-bed resin requires higher conversion rate of cation and anion resin than ordinary mixed-bed resin, because whether the conversion is completely directly related to the effluent quality, and it is difficult for ordinary users to meet the conversion requirements of polished mixed-bed resin by ordinary industrial regeneration methods, so users are not advised to do it themselves.
2) Generally, users of ultra-pure water don't use much polishing mixed-bed resin, so the significance of self-regeneration is gone;
3) If you use a large amount, you can really recycle the resin, because generally, the resin produced by our company can last at least 8 cycles, so it is really a waste to throw it away at one time.
I would also like to appeal to market customers to purchase polishing resin rationally. If your production water is above 12 megaohms or 15 megaohms, then don't blindly use polishing resin above 18 megaohms, because that will waste a lot of resources and cause a heavy burden on the environment. As a sales representative of the largest ion exchange resin manufacturer in China who has been engaged for 16 years, I thank you!
