What is a desalination function or the biocide addition?
The desalination function is an automatic process, during which the reference value is reduced by opening a desalination valve after the set limit value is exceeded.
The water supply that is now started (level control) dilutes the water in the circuit and, thus, reduces its conductivity.
In cooling towers, for example, biocides are added to the cooling water to prevent the growth of biological substances in the cooling systems. The desalination lock is started after the dosing time to ensure that the biocide does not enter the sewage system.
