Published By | Publication Date | Number of Pages |
BSI | 2021 | 56 |
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.
