How BioSTORM Works.Simple, Modular, Effective.

Pre-engineered stormwater treatment system removes trash, sediment, oil and other pollutants from stormwater runoff. The BioSTORM®’s unique off-line design consists of a patented StormTEE® self-cleaning deflector screen and a modular separation/coalescing unit, all housed in readily-available precast concrete tanks. The versatility of the system allows components to be used separately for different applications, or together to form a complete BioSTORM system. Various sizes are available depending on local site and environmental considerations.

BioSTORM Stormwater Treatment SystemsVariable flows, consistent treatment

Whether a light rain, or a heavy storm, BioSTORM’s retention of pollutants remains consistent. The unique design of the system does not rely on velocity of flow/particles to maintain high levels of liquid/solids separation. When the system is sized within proper design capacity, BioSTORM maintains consistently high- level removal of particulates, regardless of surge flows or particle velocities. In the event of heavy stormwater flows beyond design capacity, excess water bypasses BioSTORM assuring full flow of water through the storm sewer. Even while the excess flow is bypassing the system, BioSTORM continues to capture pollutants and treat incoming flow at full design capacity.

Easy maintenance

BioSTORM maintenance is very easy. Simply remove the manhole covers from each tank, insert the vacuum hose and start pumping out the oil floating inside the BioSTORM separation module. Once the oil is removed, pump out the solids from each tank or compartment. When the StormTEE® deflector screen is used, swiftly raise and lower the internal swab to dislodge any debris that may be stuck to the screen.

BioSTORM® Benefits

This pre-engineered stormwater treatment system removes trash, sediment, oil and other suspended solids efficiently & effectively – more than 90% removal rate! Maintains the treatment performance regardless of hydraulic surge flows in a unique modular design to provide efficient liquid to solids and oil to water separation. The easy to install and maintain system is ideal for pre-cast concrete tanks and only requires periodic removal of debris in the trash tank(s).
