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 standard as they are not considered to be used for tertiary clarification.

NOTE 2 Soil filtration is not covered in this standard.

NOTE 3 Activated carbon filtration is excluded from the scope of this standard as it is not considered to be a form of mechanical filtration.

This document contains details on the sampling of domestic and industrial waste water, i.e. the design osampling programmes and techniques for the collection of samples. It covers waste water in all itsforms, i.e. industrial waste water, radioactive waste water, cooling water, raw and treated domesticwaste water.

It deals with various sampling techniques used and the rules to be applied so as to ensure the samplesare representative.

Sampling of accidental spillages is not included, although the methods described in certain casesmay also be applicable to spillages.
