Process water

Demineralisation

In most cases demineralised water is produced by using a reverse osmosis installation or an ion exchanger.

water softener

Hardness in water is caused by certain salts. The major hardening ions are calcium (Ca²+), magnesium (Mg²+) and bicarbonate (HCO3-).

Membrane filtration systems

Filters are used to separate floating substances from water. There is a large diversity of filters. Therefore, it is necessary to adequately define the situation in advance before choosing a filter type.

River or canal water treatment

Due to limitations on pumping water, in certain cases it is more interesting to purify river- or canalwater into process water.

 

Rainwater treatment

In many cases rainwater is a good alternative for tap or spring water. This rainwater must usually be treated before it can be used in production processes.

die cleaning system

During aluminum extrusion, the dies are polluted with aluminum. It is important to clean the dies in a safe and ergonomic way.

Disinfection, UV-treatment

There are different ways to disinfect water. The best known are UV-, ozone- and dosing treatments.

Flux de-ironing

In the carbon steel galvanisation process it is important for the flux bath to contain a constant low iron (Fe) concentration. To achieve this a flux de-ironing installation is the most appropriate technique.

Iron removal, PCA water

Iron and manganese in water often causes problems in the production process. A custom-made iron removal installation then offers the solution.
