The static dewatering sieve continuously
removes solids from waste streams at ultra-high rates, clarifying high volumes
of process and municipal wastewater at low cost. The sloped screening deck is
fitted with stainless steel profile wire screen having slots oriented
perpendicular to the flow of material, accelerating fluid through the screen.
The deck is adjustable, providing effective control over product discharge and
degree of clarification as well as dewatering rates. An extended
acceleration/orientation ramp at the upper portion of the unit establishes a
proper feed velocity to the profile wire deck, aligning individual fibers in
the direction of flow prior to reaching the transverse slotted openings. The
unit is designed to maximize the "Coanda" effect whereby each thin
layer of fluid sliced by the profile wire screen clings to the wall of the
preceding profile wire, resulting in the acceleration of fluid through the
screen. Oversize particles are discharged from the lower edge of the screening
deck. The static dewatering sieves are offered in widths from 2 to 6 feet in
1-foot increments. Two-deck models separate two sizes of solids.
