Flush water treatment

Softening, de-ironing and demineralisation are techniques we use to treat drinking water and/or well water. All three techniques, either separately or in combination, remove undesirable substances from the water and make the water suitable for use as rinse water.

What is rinse water treatment?

Rinse water is water that you need to clean other things, such as parts of your installations. Ultrapure water is also used for cleaning products. Drinking water and well water contain substances which may be undesirable for a process. Grünbeck, therefore, develops and produces installations that effectively soften, de-ironing or demineralise (reverse osmosis). Afterwards, the water is perfect for use as rinse water.

Softening flush water

An important technique for improving rinse water is softening. You must first soften the water so that it does not leave any stains on the parts to be rinsed. Water softening is essential in any industry. Hard water is very good at causing problems in pipes, fittings and installations. We have various water softeners in our programme, including installations for private individuals, utilities, SMEs and industry. For example, our industrial installation Delta-p. This is the most economical water softener on the market.

De-ironing of rinse water

De-ironing water can be done in various ways. The most effective technique for de-ironing is the aeration (oxidation) of water. For this purpose, we have developed the fermaliQ, a de-ironing plug that uses the best and newest technologies for de-ironing ground water.

Applying reverse osmosis to rinse water

A third technique is Reverse Osmosis (RO). Grünbeck installations produce demineralised water, which we also call “desalinated water” or “demi-water”. This water is the purest water you can use in your rinsing process, and it ensures absolutely spot-free surfaces after the rinsing process.

Our water treatment, your solution

Each of our water treatment systems is unique and extensively tested before it leaves the production site. This means that it is fully adapted to the application in your organisation and guaranteed to work.


In this way, we help you to get the best out of your product, your process or your service. The only thing left to do after delivery is to connect the water supply and plug it in.

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.

De-ironed 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.

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.

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.
