1 Scope
This European Standard specifies the performance requirements for the primary settlement
of wastewater at wastewater treatment plants for over 50 PT.
The primary application is for wastewater treatment plants designed for the treatment
of domestic and municipal wastewater.
Differences in wastewater treatment throughout Europe have led to a variety of systems
being developed. This standard gives fundamental information about the systems; this
standard has not attempted to specify all available systems.
Detailed information additional to that contained in this standard may be obtained
