ールに関する。[Detailed Description of the Invention] (Industrial Application Field) The present invention is applicable to nuclear condensate purification, ultrapure water process water, etc.
The present invention relates to a multifunctional module that can be used to simultaneously purify fine particles, cladding, and both cations and anions.

きている。[Conventional technology] Conventionally, nuclear condensate was purified using the Paradex precoat method, which removed most of the ions and fine particles.
Mixed bed ion exchange resin towers have been used which can remove residual ions and salts in leak water from seawater.

いために、廃棄上の問題が生じていた。Since all of these methods are divided into two processes, each unit is not operated in a completely complementary manner.For example, even though ion exchange resins still have sufficient ion adsorption function, , fine particles or pseudo fine particles (ions that have changed to chlorine or chlorine during filter filtration) from the filter in the previous process cause clogging, and as a result, the regeneration frequency is short and the lifespan is short, making it difficult to dispose of. A problem had arisen.
