2.- Effectiveness of our technology to remove PCBs from discharged water into storm drains our technology

EFFECTIVENESS OF THE PETRO BARRIER SYSTEMS INC. TECHNOLOGY TO REMOVE HYDROCARBON OILS AND PCBs FROM DISTCHARGED WATER INTO STORM DRAINS

CASE STUDY N°.: 2

Powertech Labs, the technical division of British Columbia Hydro were commissioned to carry out experimental studies to obtain independent verification that the MLM Technology does work as claimed.

Barriers were supplied to Powertech Labs and they were requested to prepare the following test samples:

  • Transformer oil in water at 25 – 50 ppm
  • PCB (Arochlor) in water up to 5 ppm

These samples were to be tested for their concentrations of contaminants.

The prepared samples were then passed through the test barriers which had been pre-saturated with uncontaminated water. Samples of these test samples after passing through the filter barriers were then tested for total extractable hydrocarbon oils and PCBs respectively.

The Lab was also requested to pass water through the barriers and the add 10 -15 ccs of transformer oil into the barrier and report what happened to the flow of liquid. If, as expected the oil formed a solid plug and stopped flowing, they were requested to pass water into the barrier and observe whether any water flowed out of the barrier.

The results of their findings are shown below:

Lab Report Summary – Transformer Oil

Powertech Labs Inc. was commissioned to carry out experimental studies to obtain independent verification that the MLM filter technology; our patented absorption material does work as claimed.

Filter pads (sited as Petro Barriers columns in the lab report) filled with MLM filter technology were supplied to Powertech Labs Inc. and they were requested to prepare the following test samples:

  • Transformer oil water at 25 – 50 ppm
  • PCB (Arochlor) in water up to 5 ppm

The prepared samples were passed through the test filter pads, which had been pre-saturated with uncontaminated water, and were then tested for total extractable hydrocarbon (TEH) oils and PCB’s.

The lab was also requested to pass water through the barriers and the add 10 -15 ccs of transformer oil into the barrier and report what happened to the flow of liquid. As expected the oil and MLM filter technology reacted to form a complete plug. They were then requested to pour water into the barrier and observe if any passed through. None of which did.

Please see the attached Powertech Labs Inc. reports “Powertech Lab Report 1, 2 for results of their findings.
