Using Wastewater as a Resource
Filter systems that recycle wastewater or separate valuable materials dry. Our solutions support municipal treatment plants and industrial wastewater streams. We reduce wastewater before it returns to the environment.
Why aquaPROFI?
Reliable performance for harsh environments.
Protection Against Contamination
Precision wire mesh down to 2 µm guarantees clear separation. The multi-layer stainless steel mesh is robust and durable even in harsh conditions.

Minimal Maintenance
Designed for maximum serviceability. Replacement of wear parts without lifting tools and in minutes directly on site.
Suitable Coating
We have strong partnerships for high-quality coatings. For example in RILSAN or HALAL, our systems are well equipped from drinking water to the most aggressive chemicals – exactly as needed.
Engineering Excellence
We deliver not just components, but also mobile complete system solutions for demanding applications.
- In-house manufacturing from container adaptation to PLC programming
- ISO 9001 Certified

Self-cleaning – without interruption
Water flows through the filter element from inside to outside. Dirt particles remain on the inner screen – and are automatically removed.
Filtration
Raw water flows through the screen element from inside to outside. Dirt particles remain inside and form a filter cake. The differential pressure rises continuously.
- Water flows axially into the screen element
- Particles are caught on the inner screen
- Differential pressure rises as trigger


Filter Cake Formation
The retained particles form a filter cake on the inner screen. The differential pressure rises until the set threshold is reached – then self-cleaning starts automatically.
- Filter cake improves fineness
- Differential pressure monitoring triggers cleaning
- Threshold freely adjustable
Self-cleaning
When the differential pressure is reached, the flush valve opens. The motor rotates the suction nozzles in a spiral pattern along the inner screen – the vacuum precisely removes the filter cake.
- No interruption of filtrate flow
- Vacuum removes dirt precisely across the entire surface
- Only 30 seconds flush time and minimal backwash volume

Value Recovery Instead of Wastewater Fees
A multi-stage solid-liquid separation that produces dry animal feed from wastewater
Hard-to-capture fat agglomerates in wastewater are first concentrated through a filtration stage. The flotation of the load is deliberately utilized. A drum filter then separates the fat particles dry. Solid-liquid separation without consumables.
- Water Source: Wastewater in the food industry
- Application: TOC reduction to lower wastewater fees
- Challenge: Unstable fat agglomerates that float and settle
- Solution: Concentration through vertical PSK filters and dry separation via a drum. The fats are sold as animal feed.
Process Water in the Treatment Plant
Extraction from clarification basins as spray water
Process water generation from the clarification basin. Filtration of suspended, unstable flocs is the supreme discipline: the aquaPROFI filters reliably and self-cleaning.
- Water Source: Municipal clarification basin
- Application: Process water supply
- Challenge: Biological sewage sludge; unstable organic flocs
- Solution: Two self-cleaning aquaPROFI filters with large filter area
