StormWater Petro-Barrier: high flow rate hydrocarbon separator filter cartridge

The STORM WATER PETRO BARRIER™ is an in-ground hydrocarbon separator specially designed to provide continuous filtration of drainage water while retaining 100% of the hydrocarbons released from large basins or retention volumes

The STORM WATER PETRO BARRIER™ is a product designed to fit easily into your pit drains or in remote pit outlets. Designed and developed in the 1990's with the PETRO BARRIER™, the STORM WATER consists of an aluminum frame and a welded cylindrical or rectangular filter cartridge.

The STORM WATER PETRO BARRIER™ is therefore installed vertically at your low point of your polluted water discharge. The STORM WATER PETRO BARRIER™ is thus made up of 2 distinct sub-components, or chambers:

- The upper part of the STORM WATER PETRO BARRIER™, through which fluids (water, dielectric oils or hydrocarbons) or inlet chamber, is made up of several anti-debris filters and pre-filters, in order to avoid clogging of the active part of the STORM WATER PETRO BARRIER

- The secondary chamber, or active anti-hydrocarbon filter, is made of aluminum. This cartridge acts as a hydrocarbon separator and is made of a hydrophobic and oleophilic compound that saturates and solidifies when in contact with oils and hydrocarbons, but also natural or synthetic esters.

The lower part under the STORM WATER, then becomes a draining chamber, where the clean water is collected at the filter outlet, to evacuate it to your water network or directly into the environment. In fact, in all our tests for over 30 years, the water leaving the SPI filters has hydrocarbon concentrations of less than 5 ppm.


Once installed, the STORM WATER PETRO BARRIER™ can be covered with a special pre-filter made of steel grids and/or filter baskets allowing to increase the water contact surface, while decreasing its risk of clogging by sludge and organic matter.


The innovation of SPI and the interest of the STORM WATER compared to the other SPI products, is its design integrating an integrated by-pass valve: in case of heavy rain, or clogging by sludge following a violent storm, you can access the drain by simply releasing the by-pass valve, thus freeing the fluid, in order to quickly access the submerged zone, or the filter clogged by impurities. CAUTION: DO NOT PERFORM THIS OPERATION IF THERE IS OIL ON THE SURFACE AND THE WATER IS IRIDESCENT!

When the STORM WATER is installed in the pit: all retention surfaces are sloped toward the area where the STORM WATER PETRO BARRIER™ is installed for proper drainage of stormwater. The installer should prepare the area as shown and provide drainage holes for the barriers.

When the STORM WATER PETRO BARRIER™ is installed at the outlet of a remote pit (DEPOSIT® or concrete type) or at the outlet of a CHICANE BLOCK to ensure that the filtration of the ultimate traces of hydrocarbons is well treated, it can be placed in a concrete or fiberglass manhole. This way, you ensure that your sub-station, at the exit of a retention pit or a remote pit, does not release more than 5ppm of hydrocarbons into the environment

Finally, when you use the STORM WATER PETRO BARRIER™ at the outlet of a type 1 or 2 hydrocarbon separator, it ensures that in case of failure of the coalescing filter, your stormwater is treated a second time in complete safety.

The STORM WATER PETRO BARRIER™ can be installed either by customizing it to your existing manhole/sewer stopper. Either by pouring into concrete or inserting it into a concrete or fiberglass manhole in the pit, or at the outlet of an oil separator, or at the outlet of a baffle block, or transformer remote pit outlet. There are many ways to configure the STORM WATER PETRO BARRIER™ hydrocarbon separator and its locations. Finally, the STORM WATER PETRO BARRIER™ is available in several sizes, corresponding to different output rates
The STORM WATER PETRO BARRIER™ is available in various sizes to fit into existing sumps. The top filter basket attaches to the STORM WATER PETRO BARRIER™. The design of the PETRO BARRIER™ has been researched and optimized for over 20 years to facilitate maintenance and replacement operations. It is equipped with two flanges which, when installed, allow it to be removed and to have easy access to the different chambers of the PETRO BARRIER for cleaning, replacing the active cartridge or maintenance.
For lower flow rates or more standardized configurations, such as transformer holding tanks or pits, consult the SPI PETRO PIT, PETRO PIPE, or PETRO BARRIER drainage systems that equip the ERT, BCFTRFLEX or BS
