Case Study 1

In the Capital Regional District of Greater Victoria on Vancouver Island, British Columbia, a bylaw has been enacted requiring companies who discharge wastewater into storm and sewer drains to restrict the hydrocarbon oil levels to 15 PPM.

With co-operation of a major car agency in Victoria, an extended trial was carried out to develop a containment system for several storm drains and sumps which discharge wastewater into the city storm drains.

The work involved several of the products using the MLM Technology including Basket Filters, Floor Drain Petro Barriers, Petropads, and SDB-OG.

Using this combination of different products, together with recommendations in the use of cleaning fluids, the auto company was awarded a Certificate of Compliance with the Bylaw by reducing the oil contamination in the discharge water from 240-500 PPM down to 5 PPM.

Another automotive agency has subsequently been approved using the Petro Barrier products and several more have agreed to use the technology and obtain certification.

A copy of the Certificate of Compliance issued to the auto agency is shown below.

Results of Analysis of Oil and Water

Water passing through Metro Toyota Drains

Water through Drain #2 (before filter) 197 ppm
Water through Drain #7 (before filter) 426 ppm
Water through Drain #2 (after filter) 5 ppm
Water through Drain #7 (after filter) 6 ppm
