Published By | Publication Date | Number of Pages |
BSI | 2021 | 26 |
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.
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.
Soil filtration is not covered in this document.
Activated carbon filtration is excluded from the scope of this document as it is not considered to be a form of mechanical filtration.
