Product video


SPI has been an Eastern American manufacturer based in Connecticut for 30 years. Bill Gannon founded SPI in 1991 to develop a technology for solidifying polluting oils. His experience as Vice President of Liquid Waste Technologies from 1985 to 1991 and the Exxon Valdez disaster in 1989 were key elements in the creation of SPI.

In the early years, SPI focused on waste treatment by creating solidifiers for oils (Oil Bond) and for water (WaterBond). Then, in the years that followed, SPI naturally turned to pollution prevention.

SPI markets its patented Petro-Barrier, Petro-Plug and Petro-Pipe products to all customers who need to secure their retention equipment with a passive and inexpensive solution, thus allowing good drainage of rainwater without risk of overflow and therefore pollution.

No oil has ever drained from any SPI filter. SPI filters comply with American EPA SPCC standards, European and French standards on water treatment in light hydrocarbon separators as well as the water law (hydrocarbon content of water at the filter outlet less than 5 ppm , ICPE compliant). For three decades, thousands of installations have been protected by SPI products in North America, Europe and Latin America. Its approval with the largest petrochemical industries, power companies and local authorities gives it an obvious strength to innovate in the filtration and solidification of new pollutants (natural esters FR3-COPPER, synthetic esters MIDEL7131) and find the solution for which you need.
