gabionBlue Filter Gabions (BFG)
Maintaining stormwater compliance can be simple in design and easy to maintain. Our Blue Filter Gabions do not require power, chemicals, active labor, or open checkbooks to be environmentally compliant. Engineered to be LEED green – our BFG use sustainable, local, organic sources for the media blends.

blue filter gabion 2The process is simple. Gravity pushes the stormwater through its site-engineered gabions. BFG can be designed with a variety of medias – compost, vulcanized peat moss, and activated carbon. Its engineered filter bag strips out the majority of the suspended solids – protecting the medias from increased fouling, thus extending their life. Compost is well known for filtering out suspended solids, devouring oil/greases, trapping metals, and absorbing nutrients. Vulcanized peat moss is very expensive; but is extremely cost efficient when used as a polishing media for residual metals. Activated carbon is also used as a polishing media for organic chemicals.

What is brilliant is that our BRG strip out the industrial contaminates, but also slightly leaks dissolved organic carbon (DOM) into the water column on a continual basis. DOM has blue filter gabion 3been researched as a key environmental benefit in masking the bioavailability and reducing the toxic acuity of copper to aquatic species, such as salmon, trout, and steelhead. So while eliminating the toxic contaminants out of the industrial stormwater by letting nature take care of it; the BFG also releases a camouflage that hides the fish/insects from the toxic contaminates for other river sources.


Dual Stage Upflow Biofilter
biofilterThere is very unique, yet old school treatment process that has just entered into stormwater purity market. It has the ability to maximize flow capacity and solids contact with the reactive biofilter media. This, in turn, offers the ability to completely treat your facility’s hotspots with a very tight, yet simple to service treatment process package.

  • Unique in the way that a filter in an upflow configuration will tend to disrupt the ability of the stormwater to channel through the biochar media.

  • Old school in the way that industrial upflow sand filters have been in use as river intake filters for over 40 years.
    We can utilize virtually any filter media; however, the lab test results are focused solely on the use of a filter-grade biochar. Results that have showed 99% removal of metals over a year’s service. In a nutshell, we redirect the stormwater downspout into our 1st stage of separation…

  • The stormwater flows through our geotextile filter insert – stripping out the suspended solids.

  • The stormwater collects at the gravel underdrain (protected by a multi-weave filter cloth and gravity flows to the bottom of the 2nd stage.

  • The stormwater is redistributed once entering into the 2nd stage of separation and flows upwards through the biochar media.

  • The biochar media strips the total/dissolved metals, BOD, COD, and a limited amount of nutrients from the stormwater.

  • The stormwater breaks away from the biochar and flows through a grated filter screen into a clearwell.

  • The stormwater overflows into a launder collection system and gravity discharges back to the downspout outlet.

Easy to Site: Our small process unit is tight enough to fit through 30” doorways and fit into very tight spaces.
Easy to Service: No tools are needed to service any part of this BioFilter process.
Easy to Maintain: The 1st stage insert is designed to be washed out and reused.

MetalCompliant Catch Basin Inserts
The environmental authorities throughout the US are starting to focus on the non-tolerance of any metal contaminate going into any watercourse - whether it be a seasonal ditch, pond, lake, river, bay or shoreline. The prior art for metals removal in storm water lacked robustness and removal efficiency. This is primarily due to the lack of expertise and understanding in the field of separations when applying to storm water. Our MetalCompliant processes get excellent results in this matter.

The concern is how in an incredibly small space, such as a stormwater catch basin, set up a gravity process that strips out the muck, oils, fuels, and metals. We use a patented sodium exchange process using an highly engineered media that is designed for high flow, high tolerance to organics, and high exchange capacity.

It is the patented use of the sodium ion that makes us so more efficient than our competition. Its low molecular weight and single magnetic valence makes it the small guy to be easily stripped off our media’s exchange sites by the larger, more magnetically charged metals. Our competitors typically use zeolite, a mined mineral that primarily exchanges aluminum with the metals. Their problem is that the aluminum ion is a heavy weight in comparison with our sodium. And that with the zeolite being mined, our MetalCompliant media has 15 times more exchange sites per volume ratio.

That is why we can publish our process data; whereas, everyone else hides their miserable results.

There are two primary designs available for our MetalCompliant process – Blankets and Inserts.

Blankets: They can be either:

  • Set on a drainage wire rack to directly receive the stormwater outfall discharge -or-
  • download brochure
    basket style insert
    Used in a series of baffled walls in our dual compartment catch basin.

Inserts: They can be either:

  • Our light commercial Framed Insert model of which a wire frame holds the MetalCompliant insert in place.
  • Our industrial Basket Insert model of which a heavy duty basket firmly holds the MetalCompliant insert – allowing for more capacity and better performance.

Flood and Soil Erosion Control
Whether you are protecting hillsides, homes and businesses, roads or trying to control and divert floods throughsandbags, there is a easier and faster way using either our ground bladder technology or compost filter socks/blankets.

rain garden

Industrial Rain Gardens (IRG)
I remember when galvanized metal roofs were considered the perfect method of shielding an industrial building from rain leaking into it. Now with zinc being considered an industrial contaminate, having galvanized metal roofing is industrial rain garden illustrationa liability. Filtering stormwater coming off of warehouse metal roofs through passive media is a novel idea. Our passive Industrial Rain Gardens waters native plants that use some of the contaminates for cell growth, reduces zinc up to 95% and requires next-to-zero maintenance.

That is what happens when Industrial Rain Gardens were put under the rain downspouts, according to an environmental study published by the original designers at the Port of Vancouver USA. Levels in suspended solids, oils & greases, and other metals are also significantly reduced or eliminated entirely.
