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.
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.
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.
The Hydro-Static® Screen is offset from the vertical to encourage screenings to drop away from the corrugated mesh once the storm has subsided.
