Water is frequently used as a coolant in technology – this can cause a variety of problems:
- Limestone and stone deposits
- Corrosions
- algae or bacteria infestation
- Deposits of dirt particles, sand, etc.
In principle, the following types of cooling systems are distinguished:
a) closed flow cooling systems
b) Semi-open cooling systems – cooling is achieved via cooling tower
c) Closed, self-contained cooling systems (e.g., car radiators)
Semi-open cooling systems, in particular, are prone to failure.
Since only pure water evaporates in the cooling tower, the dissolved salts in the water steadily accumulate, soon exceeding the solubility limit of the salts; this results in deposits in the cooling system. Therefore, a portion of the cooling water must always be blown off (brine-treated) to prevent the solubility limit of the dissolved salts from actually being reached.
However, the more water is removed by sludge, the greater the water consumption, which has a direct impact on the operating costs of the cooling system.
By adding appropriate hardness stabilizers, the amount of sludge can be reduced, thereby saving water – at the same time increasing the concentration C in the cooling circuit.
C = Salt concentration in cooling circuit water / Salt concentration in make-up water
Increasing the concentration of C directly reduces the water requirement.
The cooling water becomes extremely aggressive due to the air introduced; therefore, the addition of a corrosion inhibitor is recommended.
Due to the air in the cooling circuit water, bacteria and algae also tend to grow particularly well—their deposits reduce the heat transfer in the cooling units
Optimal cooling water treatment can achieve the following advantages:
- Increased potential for thickening – therefore a significant water saving.
- Prevention of stone and dirt deposits – therefore optimal heat transfer and full cooling performance
- Prevention of microbiological deposits – therefore improved heat transfer (better cooling performance) and less corrosion
- Corrosion protection – therefore extending the service life of the system
