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.<\/p>\n

\n
\n NOTE 1\n <\/div>\n

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.<\/p>\n<\/div>\n

\n
\n NOTE 2\n <\/div>\n

Soil filtration is not covered in this document.<\/p>\n<\/div>\n

\n
\n NOTE 3\n <\/div>\n

Activated carbon filtration is excluded from the scope of this document as it is not considered to be a form of mechanical filtration.<\/p>\n<\/div>\n
