The EnviroProtector is a Stormwater treatment designed for heavily polluted traffic areas, suitable for installation in new existing chambers. Its fiberglass housing is saved and easy to fit on site, operating in an up-flow process with minimal head drop. The EnviroFilter at the heart of the unit employs sedimentation, filtration, adsorption, and precipitation to treat stormwater for Heavy Metals, TSS, and Nutrient reduction. It incorporates proven technology, including the Scottish Engineering Filter Media Stormwater Quality Improvement Device, with general technical approval by the German Institute of Structural Engineering. Each EnviroFilter Provides a treatment flow rate of 8 L/s, with the capability to manifold multiple units for higher flows, and requires only 250 mm fall across the device, making it suitable for flat sites.
The filter housing of this system receives rainwater for the connected area through an angled inlet which generates radial flow patterns. A Hydrodynamic separator is employed to convert turbulent waters into a radial laminar flow pattern, facilitating particle sediment thatis then trapped trapped in a slit chamber located beneath the separator, which can be easily withdrawn for cleaning.
The filter and filter roof are located in the central section of the filter housing, which filters out fine materials using an up-flow process. Dissolved materials are precipitated and adsorbed, and the filter is backwashed from above. The filter element can be easily exchanged through the access manway constructed in the roof of the body, and the filter element can be easily pulled up and removed from the shaft housing.
The cleaned water is then discharged through an outlet, and an oil trap system ensures that only clean water is released, preventing any movement of undissolved oil into the water storage, waterway systems, or free surface water. This system ensures effective treatment of stormwater, reducing pollutants and promoting the preservation of clean water
