Counter-Current system

Description

The ion of raw water is exchanged with the mobile ion of ion exchange resin and at last the exchange capacity will be exhausted. Then, in the regeneration by chemicals, it's called the counter-current regeneration, the method being performed in the opposite directions of service water and chemical injection, and the co-current regeneration, the method being performed in the same directions.

The counter-current regeneration reduces the chemicals, shortens the regeneration time, obtains the water of high purity and decreases the rinsing water, compared with the co-current regeneration.

Also, it is stable in the deterioration of raw water quality, it is possible to counter-current regeneration only with the partial reconstruction of the installed system.
