Sieve Bend Screen--Wedge Wire Screen High Filtering Efficiency
Release Time:
2026-03-27
Wedge wire sieve bends, also named as DSM screens, are typically made of stainless steel or other durable materials. They have a curved shape, hence the term "bend". The fundamental element of a sieve bend is a "wedge wire" screen, which is a surface made up of V-shaped profile wires that are resistant to clogging.
Why choose our screens?
- The screens have a very steep angle. This allows water flow to push screened material off into a dewatering hopper.
- .5 mm screens will actually separate material as small as .25 mm.
- Automatic spray bars keep dried material from clogging the wedge wire screens. Because they are timer-activated, they use 90% less water than rotary screens.
- Stainless steel construction means acidic wastewater is no challenge.
- Screening solids before pH balancing can reduce chemical consumption by 60%. Solids can soak up significant amounts of the chemical.
Why makes a good filter?
There are several important factors in selecting a good waterfall filter:
- The spacing between the wedge wire bars can vary.
- The top of the wedge wire is flat (wedge wire is made of flattened tubing) and the tops should be canted slightly so that they trap the water.
- There needs to be sufficient runway at the top so that the water can gain velocity. This is accomplished by placing a smooth section of stainless just below the weir at the top.
- The slope of the wedge wire needs to be steep. This is counterintuitive. It would seem that you would want a low slope to slow the water. Instead, you want a steep slope so that you don’t build up solids on the wedge wire screen. Water is heavy and will pass through a steep screen.
