In the dissolving unit, the dissolving water originating from the filter circuit is separated down-
stream of the booster pump (39), and the chemicals are dissolved separately. A partial flow is
directed into the flushing tank (46) via the float control valve (45). From there, it is suctioned
off by the injector (42), together with the additional chemicals dosed in the flushing pipe (44).
The chlorine granulate and the pH reducer (acid) (liquid) are dosed in turns with intermittent
breaks into the water flowing through the flushing pipe. Approx. 50% of the chlorine granulate
