WEIL Process - Neutralization

Chemical neutralization involves adjusting the pH value by adding chemicals with an acidic or alkaline reaction. Neutralization is often carried out in combination with precipitation, flocculation and separation of heavy metals or other water constituents, such as phosphate or fluoride.

For this purpose, alkalis such as caustic soda or milk of lime and/or acids such as hydrochloric acid, sulphuric acid or carbonic acid are continuously dosed into the water and mixed into a mixing tank using a static mixer in the pipework or agitator to ensure rapid and complete mixing.

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

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.
