EnviroStream Stormwater Treatment System

EnviroStream Filters are simple drop-in structures that remove over 90% of petroleum-based hydrocarbons, as well as suspended solids and dissolved metals, at a fraction of the cost of a hydrodynamic separator. They can be easily installed in either new or retrofit applications and are designed to fit any catch basin, drain or inlet.

The EnviroStream Filter uses a unique filtration medium to capture the oil and grease in the stormwater. The oil and grease becomes permanently attached to the filtration medium and it does not leach back into the stormwater.

With flow rates of over 50 gal/min, EnviroStream Filters can easily handle the first-flush of any storm event.

EnviroStream Filters are easy to maintain – the average filter needs to be changed every 8 to 10 months, requires no special equipment and takes minutes to install. Simply by weighing the filters, you can tell when it needs to be changed.
