Cleaning of Resins,

External resin cleaning of a cycle plant

The use of organic acids during galvanic processes (i.e. acetic acids) has lead to germ and bacterial contamination in the Rinsing processes. In the previous case impurities of the ion exchange resins and of the intake and exhaust nozzles hindered the hydraulic discharge rate.

Due to the strong contamination the resins were removed out of the pressure drums and submitted to an external complete cleaning in a resin back rinsing container. Thereby foreign particles as well as dead bacteriums and germs out of cation and anion exchange resins.

Resins are rinsed out. Subsequently, the resins in the back rinsing container were germinated by means of Sorbacid. Sorbacid prevents the cell division of the macro organisms and prevents germ and bacteria contamination in Water circulations. With an increased dosing quantity of Sorbacid a so-called Shock treatment was accomplished and the resins of a thorough final flushing were finally submitted.

At the same time the entire tubing in the water pipeline system was likewise subjected to a shock treatment with Sorbacid, in order to prevent a renewed germ and bacterial contamination. After cleaning and sterilization the resins were led back again into the receiving tanks. The required hydraulic discharge rate is once again assured.
