De-ironing of groundwater

De-ironised water is better for the process, extends the life, and reduces malfunctions and defects in basically everything that this water is added to. Our deferrisation installations filter out not only iron, but also manganese and other undesirable odours and substances.

De-ironing of groundwater

Groundwater naturally contains iron. Once groundwater has been de-ironised, it is better suited for your product and installations. Iron in the water can have an unpleasant odour and/or taste, and it also increases the chance of rust formation in the installations through which the water flows.

Water de-ironing is, therefore, an important form of water treatment. The most common techniques for de-ionising water are aeration (oxidation) and/or dosing an oxidising agent. Both methods ensure that both iron and manganese are removed from the water.

De-ironing of groundwater with the fermaliQ

At Grünbeck, we have developed a deferrization plant that uses the best technologies for deferring groundwater: the fermaliQ. This model combines oxidation with filtration, thus removing odours caused by hydrogen sulphide or ammonium.

How does the fermaliQ work?

Aeration is used to drive the carbon dioxide out of the water, which increases the pH value. A correct pH ensures that the iron and manganese present are oxidised into solid form. They are then filtered out of the water, together with other undesirable particles. This deferrisation installation also has an automatic backwash system. This flushes particles from the filter, after which the process can start all over again. This method of de-ironing is a water treatment that guarantees perfect water quality: without iron, manganese and other undesirable substances.

Other Grünbeck water treatment solutions

In addition to groundwater de-ironing, we also offer solutions for reverse osmosis, water softening, ultrapure water and home water softening. Each of our water treatment systems is unique and is extensively tested before it leaves the production site. This means that it is completely tailored to your organisation’s application and guaranteed to work.

Wateronthardingsinstallatie voor het ontharden van grondwater voor de industrie

Our water treatment installations often start with an industrial water softener. Pipes, fittings and installations last much longer when using a water softener. Choose a Grünbeck system and you’ll also be saving water and resources thanks to its low energy and salt consumption.

Omgekeerde osmose installatie voor gedemineraliseerd water voor de industrie

Thanks to its pure nature, demineralised water is ideal for the production of steam, boiler feed water, process water and central heating water. To demineralise water, we use reverse osmosis, or RO for short.

Waterbehandelingsinstallatie voor ultrapuur water (EDI)

Ultrapure water is created by further purifying or polishing water by means of EDI, also known as electro-deionisation. This sterile water is extremely suitable for high-pressure steam boilers and for the petrochemical and pharmaceutical industries.

Waterontharden voor thuis
In addition to water treatment for industry, we also soften water for people at home. The softliQ is the water softener that thinks for you and automatically adjusts itself to your water consumption at home. The innovative technology, with refined, low-maintenance materials, is packaged in a stylish, sleek design.
