Screening treatment by KUHN – pioneering innovation

Quality is the best solution.

The increasing volumes of screenings makes screenings treatment more and more crucial. The willingness of sewage treatment operators to make substantial investment as well as the development of manufacturers of machines and plants for screenings treatment has resulted in many improved or new technologies and methods. Today, these are used in the area of mechanical pretreatment. KUHN have been a pioneer in this area and is thus able to offer an extensive range of high-performance products and processes.

KWP-S (STANDARD) wash press

Our wash presses are deployed to supplement disposal processes where residue from upstream separation is removed, washed, compacted and dewatered. For many years, our industry-tested wash presses have proven themselves in municipal and industrial sewage treatment applications.

The basic version of the KUHN KWP-S (standard) wash press is used for screening soluble organic substances from coarse and fine screen plants.

  • Multifunctional: washes, dewaters, compresses and transports
  • Degree of removal up to 95%
  • Dewatering up to 50% of dry matter (depending on the material to be dewatered)
  • A straightforward washing system using a solenoid valve
  • Chromium chilled-cast armoring as wear protection on the screw conveyor
  • The bearings of the screw shaft can be adjusted from the outside
  • Ingenious support and counter-pressure bearing unit
  • Press zone with maintenance-friendly inspection opening
  • Powerful and uncompromising in thick-walled design
  • Removable drain basin

OPTIONAL EQUIPMENT:

  • Design version including intensive whirl wash using additional KUHN KWP-W vortex wheel
  • Increasing dry matter content by deploying the KUHN KVR Vario Resistor as a back-pressure press
  • Variant with bevel gear allows a shorter design
  • Design with special gray water valves

KWP-P (PREMIUM) wash press

Unsere Waschpressen werden als optimale Ergänzung in Entsorgungsprozessen eingesetzt, in denen bereits abgetrennte Reststoffe abtransportiert, gewaschen, verdichtet und entwässert werden müssen.
Insbesondere in kommunalen und industriellen Kläranwendungen haben sich unsere Waschpressen bereits seit vielen Jahren bewährt.

The premium version of our KUHN KWP wash press features additional equipment.

  • Multifunktional: wäscht, entwässert, verdichtet und transportiert
  • Auswaschungsgrad bis 95 %
  • Entwässerung bis 50 % TR (abhängig vom zu entwässernden Material)
  • Simples Waschsystem mit Magnetventilen
  • Chrom-Hartgusspanzerung als Verschleißschutz an der Förderschnecke
  • Lager der Schneckenwelle von außen einstellbar
  • Geniale Stütz- und Gegendrucklagereinheit
  • Presszone mit wartungsfreundlicher Revisionsöffnung
  • Kraftvoll und kompromisslos starkwandig
  • abnehmbare Ablaufwanne

ADDITIONAL BENEFITS OF THE KWP-P(REMIUM) WASH PRESS:

  • An elaborate premium washing system with hollow-shaft injection
  • An enlarged dewatering surface by means of a slotted screen along the entire floor length of the plant (especially suitable for loading of launder channel)
  • Press zone with maintenance-friendly rapid flap closure system
  • Removable drain basin featuring a drawer design

OPTIONAL EQUIPMENT:

  • Design version including intensive whirl wash using additional KUHN KWP-W vortex wheel
  • Increasing dry matter content by deploying the KUHN KVR Vario Resistor as a back-pressure press
  • Variant with bevel gear allows a shorter design
  • Design with special gray water valves

KWP-HD (HEAVY DUTY) WASH PRESS

Our wash presses are deployed to supplement disposal processes where residue from upstream separation is removed, washed, compacted and dewatered.For many years, our industry-tested wash presses have proven themselves in municipal and industrial sewage treatment applications.

The KUHN-KWP-HD wash press includes additional equipment.

  • Multifunctional: washes, dewaters, compresses and transports
  • Degree of removal up to 95%
  • Dewatering up to 50% of dry matter (depending on the material to be dewatered)
  • A straightforward washing system using a solenoid valve
  • Chromium chilled-cast armoring as wear protection on the screw conveyor
  • The bearings of the screw shaft can be adjusted from the outside
  • Ingenious support and counter-pressure bearing unit
  • Press zone with maintenance-friendly inspection opening
  • Powerful and uncompromising in thick-walled design
  • Removable drain basin

ADDITIONAL BENEFITS OF THE KWP-HD:

  • The slotted screen is made from highly stable, 3D-lasered material
  • The slotted screen is replaceable and is highly resistant to clogging due to its enlarged free opening surface
  • To increase the dewatering performance, the entire length of the pressing section is used for the slotted screen
  • Even better access for more extensive maintenance and cleaning work

OPTIONAL EQUPIMENT:

  • Design version including intensive whirl wash using additional KUHN KWP-W vortex wheel
  • Increasing dry matter content by deploying the KUHN KVR Vario Resistor as a back-pressure press
  • Variant with bevel gear allows a shorter design
  • Design with special gray water valves

KSP SCREW PRESS

Our equipment is deployed to supplement disposal processes where upstream separation residue is removed, washed, compressed and dewatered. For many years, our industry-tested machines have proven themselves in municipal and industrial sewage treatment applications.

  • Stable, operator-friendly construction
  • Extended service life with the most reliably functionality
  • Depending on the intake material, dewatering of as much as 40% of dry matter
  • Armor-reinforced conveyor screw with blade thickness of up to 30 mm
  • Press water basin with a drawer design, removable
  • Slotted screen on floor section of maximum stability and dewatering performance (the machine is especially suitable for loading of launder channel)
  • Only a few steps for accessing the press basket
  • A special support and counter-pressure bearing for sealing the press basin space (preserving the drive and protecting against wear)
  • Repositionable press screw outside the housing

OPTIONAL EQUIPMENT:

  • Design version including intensive whirl wash and additional KUHN KWP-W vortex wheel
  • Increasing dry matter content by deploying the KUHN KVR Vario Resistor as a back-pressure press
  • Variant with bevel gear allows a shorter design

KRZ SCREENINGS SHREDDER

The KUHN KRZ screenings compactor very reliably shreds screenings previously washed, dewatered and compressed in KUHN KWP wash presses. For this purpose, the KRZ unit is flange-connected directly to the press pipe (discharge chute) of a wash press. Inside the shredding housing, a shaftless screw with multiple flights ensures the screenings are securely shredded. Upon request, this can be passed onto other plant parts or machines completely encapsulated.
