A good ultrapure water machine has qualified silicon in terms of the service life of consumables. At the end of the use of consumables, there will be a short period of qualified resistance, but the silicon exceeds the standard. Why is that?
The secret of ion exchange resin refers to when silicon ions pass through the ion exchange resin column and are nearly exhausted. In the case of a standard purification tower, a decrease in resistivity (indicating that the purification column is exhausted) can be detected before silicon and boron are produced in the water. The depleted silicon is purified through the column at the later moment and eluted to a large amount of water produced in a short time. In this case, although it contains a high concentration of silicon, the resistivity purified water (representing water) has already indicated an acceptable water quality.
The dissolution of this silicon is due to the relatively low efficiency of the ion exchange tree in the mixed bed. The dissolution of silicon from the resin indicates that the ion exchange resin should be replaced.
