The report describes a comparative performance analysis of over 30 proprietary CSO / Overflow Screens tested in either a side weir CSO chamber, an extended stilling pond chamber or as stand-alone devices at the National CSO Test Facility, Wigan Wastewater Treatment Works.

Performance evaluations were made to assess the process efficiency of each screen, expressed as “screenings retention value”, at a series of inflow magnitudes and ratios of continuation flow to inflow.

The report gives a  technical description of each screen together with full test results and offers a comparison of equipment performance covering the various generic types of CSO screen currently available.
