The nrw screw separator: Economical solution for wastewater with a high content of solids.
The filtration / separation, storage or removal of highly viscous liquids often turns out to be very costly. Of course, this also includes wastewater with a very high proportion of solids.
The nrw screw separator remedies this by compressing solids from the wastewater.
Special advantages
- Excellent separation performance, even with floated slurries.
- Simple cleaning and easy replacement of spare parts.
- Particularly long service life of the screw.
- Low screw speed (5 to 24 rpm).
- Low sound level.
- Easy to transport as a mobile unit.
- Long service life even with particularly abrasive media: The especially wear-resistant spiral is made of stainless steel and tipped with carbide.
Permanently working
- High separation ridge
- Low space requirement
- Extremely low maintenance
- Designed for high durability
- Economical thanks to low drive power.
- Low-wear

Function: simple
The heart of the screw separator is a screw that conveys the medium to be dewatered from the inlet through the screen basket to the press chamber.
A compressed air operated shut-off cone closes the bale chamber. Here a plug is formed from the separated solids which closes the pressing chamber.
To achieve the desired pressing result, the back pressure of the shut-off cone can be adjusted. Feeding takes place from the top of the machine. The separated solids are discharged at the front and the cleaned substrate flows off at the bottom.
Basic equipment of the screw separator
Screw separator ASF400 in the basic version
Screw separator ASF200 with encapsulated pressing zone
Drive: Made in Germany
nrw screw separators are driven by energy-efficient and highly reliable gear motors Made in Germany.
Sieve insert
The screen insert and screw must harmonize perfectly with each other and are manufactured with the greatest possible precision.
Options screw separator
Gap widths from 0.1 to 1.1 mm
Special design with wall bracket
Gap widths
The screen basket can be manufactured in the gap widths 150 - 1100 microns.
Special constructions
On request, the systems can be manufactured as a special design, for example with an encapsulated pressing zone.
Material
- Stainless steel 1.4301
- Stainless steel 1.4571
- Special materials, for example 1.4462 Duplex (extremely corrosion-resistant)
Accessories screw separator

Electrical controls
Control incl. Safety devices as standard or according to your specification.
Sagging devices
For hygienic collection and storage of the separated screenings.
Undesirable: Odour nuisance due to unpleasant smells or vermin "hatching" in the screenings.
A sagging device provides a remedy here. This also discourages animals from searching for food in screenings and spreading it over a large area.
Feed tank
With inlet flange according to DIN or ANSI.
Elevation
Underframes for adaptation to special installation conditions.
Cleaning system
For cleaning the strainer basket.
Special design
On request, the systems can be specially
adapted to your purpose.
