Biological Processes

WEIL Process - Biological Processes

Biological purification processes are used to remove undesirable substances from water based on the natural metabolism of microorganisms. In practice, there are very different systems in which microbiological processes play an important role. Activated sludge tanks for COD removal in municipal wastewater treatment, fixed-bed reactors for the elimination of pollutants or biological filters for the removal of manure are just a few examples.

During the metabolism of the microorganisms, undesirable substances in the water to be treated are converted into other products (e.g. carbon dioxide, water). The biological processes can take place in the presence of oxygen (aerobic) or without atmospheric oxygen (anaerobic). Biological purification therefore generally requires hardly any chemicals or energy.

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


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
