It is very compact and requires minimum maintenance. The unique screen plate is made of wedge bars forming a bowed surface with horizontal slots between the bars. Normal slot width is 100 or 150 microns.
The flow to be screened is fed through a pressurized nozzle which distributes the flow tangentially over the full screen width by means of an adjustable slice providing optimum feed velocity. As the suspension flows along the screen plate, thin layers of water are "sliced off" by the screen bars and pass through the slots together with fine particles.
