WEIL Process - Degassing/Gassing

Gas exchange involves the removal of unwanted gases (degassing) or the introduction of gases (gassing) into the water. This process is used for a variety of applications, such as the introduction of oxygen for oxidation or biological processes or the removal of interfering gases (carbon dioxide, hydrogen sulphide, methane, etc.).

Both degassing and gassing are mass transfer processes that take place through the liquid-gas phase interface, i.e. in which molecules of the substance to be exchanged pass from one phase to the other. The gas exchange takes place until an equilibrium (corresponding to the saturation concentrations of the respective phases) is reached.

We advise you according to your specific requirements and work with you to develop customized solutions for the purification of your process water, drinking or wastewater with the aid of gassing or degassing. Get in touch with us or fill out our questionnaire now. We look forward to hearing from you!

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
