Bow screen

REKO bow screen for separation of solids from liquid. A bow screen can process a large amount of liquid and efficiently separate the solid fractions.

The technology works by the liquid flowing from the solid fractions through small slots in a sieve element.

  • Efficient filtration
  • High capacity
  • Simple construction
  • Easy maintenance
  • Flexibility to change filter elements for handling larger or smaller particles

A REKO bow screen is used for filtering process water. Both by e.g. washing of raw materials and handling of wastewater / residue products.

Bow screen technology is used in companies that process or produce:

  • Fruit and vegetables
  • Pork and beef
  • Poultry
  • Fish and shellfish
  • Beer and malt
  • Coffee beans
  • Starch and gluten
  • Pharmaceutical products
  • Horticulture
  • Mining and gravel
  • Textiles
  • Chemical and petrochemical products
  • Mineral products
  • Bioenergy
  • Drinking water

Additionally, bow screens are used in:

  • Wastewater treatment
  • Waste recycling

A REKO bow screen works by feeding a liquid with solid fractions / raw materials into the top of the sieve. The liquid with the solid fractions runs down over a curved element with slits. After which the liquid flows through the slits and the solid fractions / raw materials flows to the bottom of the screen. The liquid collects on the inside of the screen and is passed on through an outlet. The solid fractions / raw materials spill over the edge and down into a collecting container or on to the next production stage.

A bow screen is a simple construction but with a significant efficiency. The crucial thing for bow screens to have an optimal effect is primarily to:

  • Adapting the slot opening to the product to be filtered
  • Considering the width and height of the screen must match the product and the amount of liquid to be separated

In addition, the equipment and the process can be optimized by installing a vibrator, integrated cleaning of the slots, etc.

Also see our other slotted-products.

Slot opening: 0.15 mm to 5.0 mm

Capacity: Up to 1,000 m3 / hour

Height, width, and depth (HxWxD): from 80 x 35 x 50 cm to 140 x 200 x 90 cm


  • Vibrator on the screen plate. Used e.g. if gravity is not sufficient for the raw material to flow down the screen plate
  • Integrated cleaning on the back of the slots (2 to 200 bar)
  • Integrated CIP cleaning
  • Airtight screen
  • Function in ATEX environment
  • Other special requests and needs

It is possible and easy to disassemble one filter element and switch to another if different raw materials are used in production. And it is easy to replace the filter element if it gets damaged.

The equipment can be used in the production of food, and can be supplied with a declaration of conformity.
