Abstract: A filter system has a chamber body, an inlet that extends through the chamber body, and an outlet that extends through the chamber body at a location downstream of the inlet. The filter system has a plurality of fluid flow paths that extend between the inlet and the outlet. The plurality of fluid flow paths including first and second subsets, each including at least a respective one of the fluid flow paths. A plurality of hydrocarbon filters is disposed in the chamber body such that each hydrocarbon filter is disposed in a fluid flow path. The filter system directs the fluid to the first subset, and once each hydrocarbon filter of the first subset becomes saturated with hydrocarbons, the filter systems diverts the fluid to flow to the second subset.

Abstract: A monitoring system is configured to detect a threshold amount of petroleum in a storm water-based fluid of an oil handling facility. For instance, the storm water-based fluid can be drained from a floating roof of a petroleum storage tank, a diked area, or a retention pond.
