The non top pressure counter current regeneration ion exchanger has all the advantages of counter current regeneration, eliminates the need for a top pressure system, simplifies operation, and saves investment and operating costs. Therefore, it is currently the equipment used in desalination treatment. Inserting different resins into the column can create strong beds, weak beds, double-layer beds, etc. To form an economically reasonable desalination process.
