Wastewater treatment plants - Lagooning processes Ingestion-build-137917 – reference to IEC specification1 Scope This European Standard specifies the performance requirements for the installation of lagooning processes. This part applies to wastewater lagooning processes treating municipal wastewater from combined or separate sewerage systems and when used as a tertiary treatment. NOTE: Lagooning processes are especially suitable for treatment of wastewater where large variations in flow are experienced (e. g. resulting from stormwater).
