CQM does not affect Water quality. Cooling tower values are exactly the feed water values times the Cycles of Concentration. Dissolved matter remains in the water, causing the water to be less corrosive.
The only exception to the above is the value of the Temporary Hardness. CQM was found to reduce the temporary hardness, or the part that causes scaling by 60 – 91%, about 80% on the average.
Scale accumulates on the cathode, and is periodically cleaned by a mechanical self cleaning mechanism. Scale scrubbed from the cathodes is trapped in the sand filter of the system, and discarded during backwash.
