Rotary Screen Filters

Rotary screen filters are a kind of filter that separates solid particles from liquid by spinning a drum. The liquid is poured into the drum's centre, and as the drum rotates, the solid particles are pushed to the drum's edge. The liquid is then gathered on the interior of the drum while the solid particles are released from the filter. In order to reuse the water, rotary screen filters filter out dirt and plant materials. An infeed pipe or flume is used to feed dirty water into a revolving drum. To allow water to pass through, the drum is built of wedge-shaped wire screen with an opening of 0.2 to 2 mm.
