Procedure for Laboratory Testing of Oil-Grit Separators


OGS testingThis protocol document specifies the performance testing laboratory procedures required for oil-grit separator (OGS) manufactured treatment devices (MTDs) seeking verification under the Canadian Environmental Technology Verification (ETV) process. This document was prepared by Toronto and Region Conservation Authority (TRCA), for the ETV Program, with guidance from a Technical Advisory Committee (TAC) including representatives from Canadian municipalities, manufacturing industry, academia, engineering consultants and government agencies.

The intent of this “Procedure for Laboratory Testing of Oil-Grit Separators” is to provide a common procedure for testing and verifying the actual performance of treatment devices under controlled conditions, in an independent, transparent manner. It is anticipated that independent verification of the performance data will assist regulatory agencies, permitting authorities and other affected stakeholders in evaluating treatment technology options.

The final testing protocol, which was updated in June 2014, is now available under ‘downloads’ on the right side bar.
