Parabolic Rundown Screens

Parabolic Rundown Screens / Waste Water Screening Machines cover Parabolic Screens, Rundown Screens and Static Screens

Parabolic Rundown Screens is a general term we use to cover Parabolic Screens, Rundown Screens and Static Screens. Parabolic Rundown Screens are widely used in many processes and effluent conditions for the efficient separation of liquids & solids.

The non-mechanical, low maintenance aspects of Parabolic Rundown Screens relies on a uniform feed over a fabricated distribution weir, a reversible wedge wire sieve bend with a cross-flow presentation to allow effective dewatering and gravity solids discharge. Standard radii at varying widths are available to suit flow rate and slot gap requirements of our Parabolic Rundown Screens.

Parabolic Rundown Screens

Parabolic Rundown Screens are available as standard, with all wetted parts being manufactured from 304 or 316 grade stainless steel.

A mild steel painted or galvanised carcass can be provided for our Parabolic Rundown Screens to accommodate low budgets and client specific applications. Variations to the manufacturing of our Rundown Screens standards can include as-built or retro-fit spray bars with top and front covers incorporating hinged inspection doors (these also cover our Parabolic Screens and Static Screens).

Vibrating, Static Rundown Screens are easy to operate, and we offer a wide range of solutions in relation to the customers individual requirements, slot size and the screen’s profiled wire. The size of the rundown screen depends on the application and the required capacity, whereas the cleaning will depend on the size of the slot used.
