Berm Barriers allow contaminated water held within a bermed area or holding pond to be cleaned of hydrocarbons and safely discharged as it accumulates, without the need to ever have a shut-off valve manually operated.

Using a parallel arrangement of filters, the Berm Barrier can remove over 10 US gallons of oil before being saturated, and will remove oil sheen and oil contamination to levels

below one part per million

. If a major spill occurs that would saturate the filter material, the filter will automatically block through a chemical reaction and contain the spill within the bermed area. This results in easy recovery and cleanup of the spilled oil without contaminating the local environment, saving huge amounts on remediation, cleanup and potential liabilities.

Berm barriers can also be set up to filter out metals and other non-hydrocarbon contaminants based on the needs of the site.

Large sites such as transformer vaults and storage tanks often face problems with filtering small concentrations of oil out of very large quantities of water that accumulate from weather or normal operation. While large mechanical oil-water-seperator installations are often able to recover hydrocarbons from water when concentrations are high, they frequently lose effectiveness at concentrations that still exceed local environmental regulations.

Containing this water in tanks or bermed areas is a common mitigation measure, but does not solve the underlaying problem of contamination. Additionally, water build up has to eventually be released, often through horizontal drains with valves that are placed into the walls of bermed areas. If liquid overflows the walls of the berm, or if a valve is not closed properly or malfunctions for any reason, contaminated water can then be released into the region, potentially resulting in huge cleanup and liability costs.

The Berm Barrier solution from Petro Barrier Systems allows companies to continue to use containment berms, but eliminates a potential failure point of mechanical operation and human error. Due to the filtration techniques used, the Berm Barrier also does not lose effectiveness as concentrations drop to oil-sheen levels(about 15 parts per million) and below, which can be a problem with mechanical separators during wet weather.

The water would then be chemically treated while in the drum to cause most of the silt and other solids to precipitate out, collecting in the drum over the course of multiple treatments until sufficient had accumulated for normal disposal.


Oil Spill Defence � Pressure Filter Systems

Pressure Filter Systems can range from small systems for onboard personal watercraft to large systems suitable for hazmat water handling at large power utility sites, and can be created either as an add-on to an existing water handling system or designed from the ground up.


Oil Spill Defense - Storm Drain Protector

Storm drain systems in populated areas are a prime culprit for carrying this pollution to water sources, and a moment contemplating the sheer number of drain inlets in a single city should make it clear why little media exposure is turned on the issue due to the lack of clear targets to implicate as offenders.


Oil Spill Defense - Floor Drain Protector

Even just a few drops of gas being spilled while filling a lawnmower or a car driping oil in the garage for a few days before being fixed will often result in these oil products eventually finding their way into drains, and from there onwards into our waterways.


Oil Spill Defense - Products For A Cleaner Environment � Environmental Safety Solutions

Fitting into a variety of standard drainpipe sizes up to 12" in diameter, the Pipe Protector will filter out small concentrations of oils, and will automatically block in the case of major spill - making cleanup easier and vastly reducing environmental impact. Petro Barrier Systems is dedicated to ensuring that pollutants are removed before they enter the marine environment, and recognizes that everyone's problems can be a bit different.
