Product Description

Model 291 Static Gravity straining elements are triple sloped design, slotted, wedgewire screen with multiple slot widths oriented horizontally across the direction of flow. The decks are positioned at a steeply sloped angle providing an effective stripping of liquid and allowing the solids to slide off the discharge lip. These are typically used when the solids are easily separated from the liquid and where the separated solids slide easily.

Method of Operation:

Wastewater or slurry is gravity fed or pumped to the headbox. The wastewater then drops down onto a triple sloped screen design that orients the flow tangentially onto the screen surface. The liquid passes through the openings in the wedgewire to a drainage area, located under the screen, and the solids slide down the surface of the screen to the discharge lip. Solids greater than the opening are retained on the screen surface where they build kinetic energy and roll downward off the screen to reuse or disposal. With free drainage material, most of the free fluid is removed in one pass.
