This standard specifies definitions, principles of sizing, installation, operation and maintenance of separator systems for light liquids in accordance with prEN 858-1:1997 as well as requirements and test methods for cleansing agents discharged with the waste water into the separator system. When pollution control requires the treatment of pollutants other than light liquids, additional measures shall be necessary.
