Ion Exchange

for the selective removal of ions from (waste) water

WEIL Process - Ion­Exchange

Ion exchangers are used for the selective removal of ions from water or aqueous solutions. They are usually used for softening, partial or complete desalination.

The principle of ion exchangers is based on replacing ions (=electrically charged particles) dissolved in the water with other ions from the ion exchanger material. Usually, granular, solid synthetic resins are used as the ion exchanger material. They must be insoluble in water and chemically resistant, but above all they must be suitable for ion exchange.

We advise you according to your specific requirements and work with you to develop customized solutions for the selective removal of ions from your process water and drinking water. Get in touch with us or fill out our questionnaire now. We look forward to receiving your enquiry!

Application and Industry Examples

Our team of engineers and technicians will accompany you from the very beginning


We come to you! For the inventory and an on-site inspection, we will come by your place.

Water analysis

Whether it is softening, reverse osmosis, or adsorption on activated carbon - whichever method it is, a detailed analysis of the raw or wastewater is the basis of the further planning.

Reverse Osmosis System

Pilot test

A pilot test serves as the basis for the selection of the method and the dimensioning of the cleaning system. Weil Wasserbehandlung GmbH offers pilot tests, including measurement campaigns, at your site.

Evaluation and reporting

The results of the preliminary tests provide an objective basis for the decision on the optimal design of the water treatment.

We manufacture softening systems with individual valve control on an individual basis and according to your specifications

Water treatment plant

After a successful consultation, you will receive a made-to-measure offer for a water treatment system suitable for your requirements.

Delivery, installation and commissioning

The prefabricated system parts are delivered, assembled on site and put into operation by our engineers and technicians - also internationally.

Maintenance and repair service

Regular service with maintenance and repair work by our service technicians make our offer complete for you.

We are happy to advise you
