JDV - Step/Fine Screen
The JDV Step/Fine Screen is a proven design as a reliable self-cleaning fine bar screen for fully automated removal of solids from industrial or municipal wastewater. Removal of the non-organic solids helps increase operational plant efficiencies, particularly for downstream processing. The screen`s design results in very low head loss and is ideal for in channel applications.
The working principle is simple, but ingenious, using rows of self-cleaning bars in a stair step configuration. Every other bar is fixed and the remaining bars are part of a movable fixture that rotates to deposit screenings on the next "step" up, progressively lifting debris step-by-step for discharge at the top. The operating sequence is regulated by the differential level of wastewater across the screen allowing the screenings to gather and form a pre-coat which is removed to the next step when the proceeding cycle is initiated.
The JDV Step/Fine Screen normally operates intermittently to minimize unnecessary wear & tear and to maximize operational efficiencies.
