ClearBlu manufacturers wedge wire waterfall screens as a highly efficient and cost effective alternative to other solids removal systems. A number of factors make these wedge wire screens an excellent choice.

  • The wedge wire 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.

0-150 GPM Wedgewire Screen

This wedge wire screen is designed for flows from 0 to 100 GPM for hydro screens. ClearBlu screens are unique in that they have a 55-degree slope and are self-cleaning in most applications. They have no moving parts. The concept is simple: run the wastewater over a weir and down over a wedge wire screen. The solids are pushed off the screen and the liquids pass through the wedge wire.

There are several important factors in selecting a good waterfall filter. First, the spacing between the wedge wire bars can vary. Second, 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. Third, 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. Fourth, 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. Manufacturer: MiTM

150 to 250 GPM Wedgewire Screen

The Model 2 waterfall screen has six square feet of wedge wire screen surface and is half the size of the Model 3. This wedge wire screen effectively removes solid particles from a waste stream. Like the other types, this model uses very little energy and requires only a minimum amount of maintenance. It’s ideal for many different applications including agriculture and manufacturing.

400 GPM Wedgewire Screen

This unit will handle flows up to 200 gallons per minute. It has a 1 MM wedge wire screen. The key to hydro screens is having the correct angle on the screen and having enough runway for the water so that it gains sufficient velocity over the wedge wire screen. This seems counterintuitive. Most manufacturers lower the slope and try to slow the water. This creates clogging and water bypass.

Our unit has a 55-degree slope. The screen is 48″ wide and 36″ long. The unit is stainless steel.
