Stormwater Filtration
Best management practices for stormwater management includes minimizing the amount of oils and sediment that enter the environment.

Installing a filtration system does provide additional benefits in comparison to oil/grit separators.

Under normal operating conditions, stormwater flows into the upper by-pass chamber and is diverted down a pipe into the treatment chamber. This downward flow is directed by a tee outlet around the circular walls of the chamber located horizontally to the outlet pipe. Above and below this through flow, oil and sediment accumulate in relative quiescence. Inflowing fine sediment and grit settle to the floor of the chamber, while petroleum products rise and become trapped underneath the fiberglass insert.
The system is available for many different applications, such as, inlet, in-line and submerged as shown in the illustrations.
