1Recommended new process flow: The use of ion exchange resin has the advantages of low initial investment and less space occupation. However, the disadvantages are that it requires frequent ion regeneration, consumes a large amount of acid and alkali, and causes certain damage to the environment.

　　2The traditional process flow: Reverse osmosis is used as pretreatment and combined with ion exchange equipment. Its characteristic is that the initial investment is higher than that of the method using ion exchange resin, but the regeneration cycle of the ion equipment is relatively longer, and the consumption of acid and alkali is much less than that of the method using ion resin alone. However, it still has a certain degree of damage to the environment.

　　3New process flow: Reverse osmosis is used as pretreatment and then combined with electro-deionization(EDI)This device is currently an economical and environmentally friendly process for producing purified water. It can continuously produce purified water without the need for acid and alkali regeneration, causing little damage to the environment. Its drawback lies in the fact that the initial investment is relatively too expensive compared to the above two methods.
