For chemical (waste) water treatment

WEIL Process - Precipitation/Flocculation

Precipitation and flocculation are chemical water treatment processes that convert dissolved or non-separable water constituents into a separable form. Precipitation/flocculation is usually followed by a further treatment stage (filtration, sedimentation or flotation) to separate the substances from the water.

During precipitation, precipitants such as iron and aluminum salts are added to the water, which react chemically with certain dissolved substances in the water. This reaction converts the substances into insoluble and therefore separable compounds.

Flocculation in water treatment involves the agglomeration (clumping) of colloidal and finely suspended substances in the water through the addition of flocculants, such as polyelectrolytes, in order to increase the efficiency of floc formation.

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
