The simplicity of the SHS sidehill static screen (also known as a parabolic or rundown screen) makes it a good choice for static dewatering screen applications, especially in a bypass or overflow channel where the screen sees only occasional use.
Sidehill static screens are free-standing, easy-to-install and have no motor or moving parts to wear out resulting in a low maintenance solution. Yet the screen is an effective solids separation device as gravity does the work.
Sidehill static screens are typically used when solids are easily separated from liquids and when the separated solids slide easily on a sloped surface. Wastewater flows by gravity into the headbox where it then overflows a distribution weir onto a steeply sloped parabolic screen filter surface. Liquid passes through the openings in the wedge wire to a drainage pan while the solids slide down the surface of the screen to the discharge lip where the liquid is recirculated or discharged.
