Wyma Rotary Screen Filter

Wyma's Rotary Screen Filter is compact and cost-effective. It is a first-stage water treatment solution that removes vegetable matter and debris from water so it can be reused.

Dirty water is fed into a rotating drum via an infeed pipe or flume.

The drum is made from wedge wire screen (aperture 0.2 - 2mm) to allow water to pass through. Water is collected underneath the rotating screen in a catchment tray or tank.

Debris stays on the screen and is carried to the waste chute via flights fitted inside the drum.

An internal cleaning bar sprays water on the outside of the drum to dislodge waste and prevent it from clogging the screen.
