Process water

Many industrial plants may use waters of varying quality, other for production, energy or auxiliary processes, therefore water treatment installations can be simple or very complex. In many cases, waste water from one process can be a source for other less demanding processes after treatment.

The composition of water in individual production branches may significantly differ in the physicochemical and microbiological composition of water, e.g.

•     The food and food processing industries usually require drinking water quality, but for some applications high-quality water devoid of oxidants, fragrances or nitrogen compounds,
•     The textile industry uses water without color, iron and manganese compounds, softened for the purpose of washing and dyeing fabrics,
•     Depending on the production profile, the pulp and paper industry requires water with a low color and oxidation capacity, soft iron-free, manganese-free,
•     Machine industry mainly electroplating requires demineralized water with low conductivity,
