How It Works

Filter, Absorb, Contain

SPI's Patented Technology To Filter, Absorb and Contain

SPI Petro-Barrier™, Petro-Pipe® and Petro-Plug® products use patented filtering technology that allows water to drain while providing a total oil spill containment system. Water enters through the top of the products and filters down through three different layers of filtration media. The filtration media removes oil sheens to non-detectable levels.

SPI Provides Total Oil Spill Containment

In the event of an oil spill, the oil/water filter forms a plug and becomes an oil spill containment system, preventing oil from being released into the environment and allowing cleanup at the spill site. No other technology offers the reliability of water drainage and proven oil spill protection 24/7/365 without sensors, oil/water separators, pumps or valves.

SPI oil containment products and systems have been successful in thousands of applications since 1999. This technology can be used in the design of new oil containment projects or easily retrofitted for oil tanks or transformers to comply with the Environmental Protection Agency’s Spill Prevention, Control, and Countermeasures (SPCC) regulations. The SPI Petro-Barrier™, Petro-Pipe® and Petro-Plug® are all acceptable methods to provide oil spill containment required under SPCC regulations.

How SPI Spill Containment Products Have Been Tested

With thousands of installations completed, SPI Petro-Barrier™, Petro-Pipe® and Petro-Plug® products have undergone extensive field testing. No oil has ever escaped from an oil spill where any of these products were installed. SPI’s products have also been third-party laboratory tested, leading to recent acceptance by the Florida Department of Environmental Protection to allow use in rainwater discharge from oil containment areas. Third-party testing of total petroleum hydrocarbons (TPH) found less than 1 ppm or non-detectable TPH levels in oil contaminated water after it had gone though SPI filters.

Transformer Containment

Petro-Pipe® Contains Leakage From Substation Transformer Explosion
Oil bond
A transformer explosion exposed the Petro-Pipe® to more than three hours of fire before the fire was extinguished.
The flanged Petro-Pipe® is shown after the fire is extinguished. On the right there are two holes drilled through the concrete into the oil containment sump for water drainage; this is where burning oil entered the sump.
Despite extreme conditions, no oil escaped the containment sump as shown here after the Petro-Pipe® removal and in the previous photo of a worker removing the Petro-Pipe®.
The Petro-Pipe® housing is hammered out of the concrete; the flanges were melted and fused together. No oil escaped past the Petro-Pipe®. (The area where the worker in standing.)
The Petro-Pipe® flanges melted and fused together, preventing any oil from escaping. 

SPI demo tubes used in our trade shows & customer meetings show how our unique patented products work.

Demo test sample showing how water flows through SPI products.
The media absorbs the oil, forming a seal that prevents any oil from discharging.
Oil is added to the test demo tube; as the oil is absorbed, the media starts to turn a darker color.
Unused media is removed, leaving only the total seal.
