How it Works
The Heliscreen® is a simple, powered screen that uses a
semi-cylindrical stainless steel perforated plate on the sanitary
side of the overflow weir, effectively keeping all matter greater
than 6 mm in the continuation flow to the wastewater treatment
facility.
When the water level reaches a predetermined level the rotating
helical brush mechanism is initiated. This ensures debris
is brushed from the screen face and carried away with the
continuation flows.
An important benefit is the ability of the screen to operate
in a totally flooded chamber when continuation and/or spill
flow pipes are surcharged.
Typical Design Loading Rate: 350 l/s/m2.
