Water treatment for cooling water
Use of water
in cooling circuits
In power stations, industry and commerce, waste heat has to be dissipated, i.e. a cooling circuit is required. The most commonly used coolant is water. The cooling circuit can be open, closed or be designed as a hybrid solution. Open cooling circuits are the most widespread.
In an open cooling circuit, chemically pure water is extracted from the circuit by evaporation and dissolved salts as well as other contaminants are left behind. This process is called cycles of concentration.
In order to run the cooling circuit at a target cycles of concentration, a portion of the cooling water is discarded at regular intervals (blowdown). These losses must be compensated for with treated make-up water.
Water treatment
for cooling systems
Suitable water treatment is indispensable when it comes to operating cooling systems with the highest possible cycles of concentration and thus low water consumption. In addition, the 42nd German Federal Immission Control Act (BImSchV) requires monitoring of the cooling water in order to prevent microbial contamination.
We offer all the required technology for cooling tower applications – from treating make-up water with softening units and reverse osmosis or nanofiltration for higher cycles of concentration to our specially developed dilution control system, Cooltrol data, which features an extensive range of functions and documentation of the operating data.

Reverse osmosis system with PLC
Special system for the treatment of hardness-stabilised raw water. For innovative and clearer operation, the reverse osmosis system is equipped with a memory-programmable control system. In addition, this control technology enabled the implementation of a BUS connection for data transfer to the BMS (BACnet in this case).
