Abstract
A chamber having an inlet for receiving polluted storm-water runoff and an outlet for the storm water to flow out. Within the chamber is a pivotal filter that catches clay during typical storm flows and pivots out of the way during higher flows. In alternative embodiments, there are included a screen, one or more baffles, and/or a collection reservoir for further dispersing, detaining, and/or filtering the storm water.
Claims20
A trap for separating pollutants from a liquid, comprising:
- a chamber having an inlet and an outlet;
- and
- a pivotal fibrous filter disposed in the chamber between the inlet and the outlet, wherein the pivotal fibrous filter is configured to separate some of the pollutants from the liquid and pivots from a filtering position when a typical flow of the liquid is flowing through it toward a bypass position in response to a larger-than-typical flow of the liquid engaging it, wherein in the bypass position the pivotal fibrous filter permits the liquid to flow out of the chamber outlet without passing through the filter.
A trap for separating pollutants from a liquid, comprising:
- a chamber having an inlet and an outlet;
- and
- a pivotal fibrous filter disposed in the chamber between the inlet and the outlet, wherein the pivotal fibrous filter is configured to separate some of the pollutants from the liquid.
