This document specifies design principles and performance requirements for tertiary clarification (receiving effluent from secondary treatment) by physical filtration plant at wastewater treatment plants serving more than 50 PT.

NOTE 1

Ultrafiltration, nanofiltration and reverse osmosis are not covered within the scope of this document as they are not considered to be used for tertiary clarification.

NOTE 2

Soil filtration is not covered in this document.

NOTE 3

Activated carbon filtration is excluded from the scope of this document as it is not considered to be a form of mechanical filtration.
