In case of drilled wells, the high dissolved iron, and occasionally, manganese content of the water is often a problem.

These ions, present in the water in dissolved form, cause no discolouration, but are precipitated when exposed to the air’s oxygen, causing a brownish-yellowish discolouration in the water and on the surfaces in contact with it.

When applying our iron removal equipment, the pre-oxidation of the water’s iron content is necessary. As a consequence of oxidation, the iron ions dissolved in the water are precipitated, and can thus be filtered.

For dosing the oxidising agent, we recommend the Navidos quantity-proportional chemical dosing device, that adds the required chemical proportionally to the quantity of the water to be treated.

Following the oxidation, the filter charge of the equipment filters out the precipitated iron and manganese ions, thereby preventing discolouration of the water and its contact surfaces.
