For a safe and low-maintenance operation of membrane activated sludge plants, hair, fast substances, etc., which can form undesirable plugs in the membrane biology, must be screened out of the raw wastewater. However, the organic contents from the screenings should be returned to the biological treatment stage as a carbon source.

For decentralized membrane wastewater treatment plants, a simple and inexpensive mechanical pre-treatment for the separation of screenings and grit is required. The CUBE Fine Screen meets these requirements by combining vertical fine screening with screenings washing and a circular grit trap. The separated solids can be discharged via a dewatering screw. The separated screenings and the accumulating sand can also be sucked directly out of the container by means of a suction device.
 

Range of application

• mechanical pre-treatment stage for decentralized wastewater treatment plants
• fine screening < 3 mm hole diameter (especially suitable for membrane activated sludge plants)
• flow rate max. 7 L/s
