CONTRA-SHEAR  -  THE ORIGINAL

Rotary Fine Screen
The contra-shear Milliscreen model is the industry standard when it comes to rotary fine screening. Its a self-cleaning, internally fed rotary screen suitable for fine screening of sewage, industrial waste water and process streams.

With more than 15,000 installations worldwide, Waterco has by far the most diverse application experience in the industry.

The Milliscreen rotary screen is commonly installed above channel with the influent either pumped or flowing by gravity into the screen. A weir tank inside the screen drum balances the flow and distributes it evenly over the rotating
screen drum.

Depending on the application, the drum can be constructed out of Vee-Wire® screen, perforated plate or mesh. Solids are captured inside the screen drum where they are dewatered and discharged using a series of diverter plates.

The Milliscreen drum is cleaned by using water under moderate pressure through two sets of sparge pipes that operate intermittently through a control system.

The wide range of Milliscreen models are capable of handling flow rates from 2.6 to 14,795 gpm (0.6 to 3,360 m³/hr).
