Abstract
By passing an alkali regenerating agent A through a basic anion exchange resin (3), and through a strongly acidic cation exchange resin (4), the basic anion exchange resin can be regenerated while amphoteric organic materials such as the amino acids captured at the strongly acidic cation exchange resin can be desorbed. Then, an acid regenerating agent B is passed through the strongly acidic cation exchange resin to regenerate the strongly acidic cation exchange resin.
Claims12
A regeneration method for regenerating ion exchange resins in a mixed-bed type sugar solution deionization system which is filled with a strongly acidic cation exchange resin and a basic anion exchange resin and which performs deionization of sugar solution, said method comprising the steps of
- contacting an alkali regenerating agent with both said strongly acidic cation exchange resin and said basic anion exchange resin, and
- contacting an acid regenerating agent with said strongly acidic cation exchange resin.
A mixed-bed type sugar solution deionization system filled with a strongly acidic cation exchange resin and a basic anion exchange resin, which performs deionization of sugar solution and in which said ion exchange resins are regenerated, comprising,
- a controller for controlling the flow of an alkali regenerating agent and an acid regenerating agent, such that said alkali regenerating agent first comes in contact with said basic anion exchange resin and then said strongly acidic cation exchange resin, and said acid regenerating agent then contacts said strongly acidic cation exchange resin.
