Overview
A compact, powered screening system with the ability to operate
under surcharged conditions. The newest addition to HRD
Technologies' portfolio of CSO solutions, the Heliscreen®
is a powered screening system for the removal of floatables,
gross solids and other sewer debris greater than 6mm in
two directions. The Heliscreen® also has
the unique ability to operate under submerged conditions.
Compact and adaptable, the Heliscreen® is
ideal for installation at new or existing CSO facilities
where a low maintenance system is required but site constraints,
hydraulic levels and/or chamber dimensions preclude the
use of HRD Technologies' non-powered, self-cleansing screens.
