Sieve Bend Screen

Solid Liquid Separator June 7, 2024 Sieve Bend Screen

Sieve screens can be classified based on the size of their openings into coarse screens and fine screens. They can also be categorized by their operation mode into stationary screens and rotary screens.

Stationary Screens, also known as Sieve Bend Screens

The Sieve Bend Screen consists of curved bars and a frame, forming a gradually decreasing angle surface from top to bottom. The bars are horizontally placed with a wedge-shaped cross-section. The spacing between the bars ranges from 0.25 to 5mm.

Working Principle: Wastewater enters from the back of the screen into the upper section of the bars, then overflows across the width of the bars towards the front. As the wastewater flows over the bar surface, water passes through the gaps between the bars, flows into the lower section of the bars, and exits through the outlet.

Debris is retained by the bars and slides down the screen surface into a sludge trough due to hydraulic flushing and gravity. The Sieve Bend Screen is suitable for removing fine fibers and solid particles from wastewater and is commonly used in small wastewater treatment plants.
