Source: Veolia Water Technologies
The Escalator gives continuous fine screening for channel type applications with superior efficiency to slotted and bar screens. This highly versatile screen is successfully employed in wastewater, stormwater and potable water applications.
The fine screen with differentiating advantages:
- Higher capture rate with either 1/8” or ¼” perforated fine screen
- Lower head-loss because of higher open area
- Larger materials are lifted with step-shaped panels
- Easier retrofitting into existing headworks
The pre-assembled unit’s design is of the endless mobile belt type, using multiple panels with holes. It gives highly efficient fine screening in any direction. Structural shelf on perforated panels lifts larger «unmattable» solids. Panels are carried on heavy duty chains. The self-adjusting system of the rotating brush provides an annual average capture rate increase of at least 20% resulting in a reduction of plant workround costs.
