WEIL Process - Filtration - Fabric - Plastic - Sand - Gravel

Various filtration processes and filter media are used in water treatment, especially for particle separation. They are based on the principles of sieving and surface or depth filtration.

Tissue and plastic filters

Filter inserts made of plastic fibres (polypropylene, polyester, viscose, etc.) are also frequently used as filter media. The industrially prefabricated filter inserts are manufactured as filter cartridges, bag filters, filter fleece or filter cloth.

Gravel and sand filters

Sand (gravel) is often used as a filter medium. The filter systems consist of a container (e.g. made of steel, GRP or concrete) which is filled with filter sand and through which the water to be treated is channelled. If the sand filters are used for deferrisation and demanganisation, the water is usually aerated first.

We can also consult you on membrane filtration or specifically on reverse osmosis.

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
