Screen gross solids and floatables at CSO sites with infrequent overflows.
Though overflows may be infrequent, when they occur they are still damaging to the environment. The Hydro-Static® Screen offers an economically sustainable screen for combined sewer overflow sites with infrequent overflows, but at which environmental protection is still a concern.
Overview
The Hydro-Static® Screen offers an economically sustainable screen for combined sewer overflow (CSO) sites with infrequent overflows, but at which environmental protection is still a concern. A non-powered screening technology, the Hydro-Static® Screen provides effective gross solids and floatables capture and works with small flows and small budgets.
The Hydro-Static® Screen is available in two configurations, either as an Up-Flow screen or a weir-mounted Through-Flow screen. With no moving parts and flow-modifying components in the up-flow configuration to provide partial cleaning, maintenance is kept to a minimum. To protect against corrosion components are typically supplied in grade 304 stainless steel as standard, and the mesh screen panels are coated in a non-stick polymer to reduce blinding.
Configurations
Up-Flow
The Hydro-Static® Screen is mounted horizontally over the dry weather flow channel so that the flow passes up and through the screen in a storm event.
Through-Flow
The Hydro-Static® Screen is offset from the vertical to encourage screenings to drop away from the corrugated mesh once the storm has subsided.
Applications
CSO sites with infrequent spills
Floatables control within collection systems
Retrofits or new CSO screening facilities
