Process water = cooling water, boiler feed water, DI water or ultrapure water.

Production of process water with low conductance

The umbrella term process water stands for the service water or process medium in various production, cleaning and operational processes.

Due to the wide range of possible applications, the requirements for the purity of the water and thus the production of the process water are changing.

E.g., reverse osmosis (EASYRO®): removes suspended matter, smallest molecules and germs almost completely (95-99%).

The result, depending on the quality of the input water, is purified water with a low conductance.

Process water with 0.055 - 0.1 µS/cm

Fully demineralised water (DI water) is obtained from raw water by ion exchange (deionisation).

The E.KO IONISER® works like a sponge, completely removing all dissolved salts and ions from the water = conductance of 0.1 µs/cm.

If the raw water is pre-cleaned (reverse osmosis) and then smoothed (deionisation), the result is purest water with a conductance of 0.055 - 0.1 µS/cm (ultrapure water).

Purity level of process water

The degree of purity of the process water depends on its conductance (µS/cm).

The fewer dissolved charged salts and ions (electrolytes = cations and anions) there are in water, the lower its conductivity.

Another important parameter is the DOC (Dissolved Organic Carbon) or TOC (Total Organic Carbon) value of the process water.
An increased DOC value indicates contamination with organic substances.

Organic contamination

Organic impurities in the water cause problems.

They can lead to microbial contamination of the machine components and form deposits of slime, algae or mould.

Reverse osmosis is the optimal choice here. The fineness of filtration is 0.0001 µm. Thus, microorganisms are almost completely filtered out of the water.
