Scumboard Performance Analysis

Price: £100


Ref: 99/WW/08/8
ISBN: 1 84057 184 5

A performance evaluation was carried out to assess the influence on the total solids retention efficiency and the water depth in a side weir CSO chamber when changes were made to the position of a scumboard within the chamber. All tests were completed at the National CSO Test Facility at Wigan Wastewater Treatment Works. Similar measurements were made when a Rotomat ROK1 6mm mesh screen was installed horizontally to the downstream face of a side weir. Tests were completed with and without the scumboard in position for a series of inflow magnitudes and ratios of the continuation flow to inflow.
