Abstract

An inlet filter includes a frame, filter material, a feed stream inlet, and a filtrate outlet. The frame includes a thick portion and a narrow portion. The frame also includes a spring-comprising portion having an adjustable height. A method includes inserting an inlet filter into a storm sewer inlet. The inlet filter can be one of a plurality of inlet filters inserted into the storm sewer inlet, the filters cooperating to filter a feed stream entering the storm sewer inlet. A system includes a plurality of inlet filters configured to be coupled together to filter a feed stream to a storm sewer inlet. The system can be configured so that the width and the height of the plurality of filters is adjustable. For example, a first inlet filter and second inlet filter can be slidably engaged with a connecting filter.

IPC Classes  ?

• E03F 5/04 - Gullies with or without odour seals or sediment traps
• E03F 1/00 - Methods, systems, or installations for draining-off sewage or storm water
• E03F 5/06 - Gully gratings

Abstract

An inlet filter and method of use are disclosed. In one aspect, the inlet filter comprises a frame, filter material, a feed stream inlet, and a filtrate outlet. The frame is configured so an exterior of the frame is shaped like a wedge. In another aspect, the method comprises inserting an inlet filter into a storm sewer inlet. The inlet filter can be one of a plurality of inlet filters inserted into the storm sewer inlet, the filters cooperating to filter a feed stream entering the storm sewer inlet. In a third aspect, a system comprises a plurality of inlet filters configured to be coupled together to filter a feed stream to a storm sewer inlet. The system can be configured so that the width of the plurality of filters is adjustable. For example, a first inlet filter and second inlet filter can be slidably engaged with a connecting filter.

Abstract

An inlet filter and method of use are disclosed. In one aspect, the inlet filter comprises a frame, filter material, a feed stream inlet, and a filtrate outlet. The frame is configured so an exterior of the frame is shaped like a wedge. The frame comprises a thick portion and a narrow portion opposite the thick portion. The thick portion of the frame comprises the feed stream inlet. The filter material is positioned along a bottom surface of the frame and a portion of an upper surface of the frame that is opposite the feed stream inlet in the narrow portion of the frame. In another aspect, the method comprises inserting an inlet filter into a storm sewer inlet. The inlet filter can be one of a plurality of inlet filters inserted into the storm sewer inlet, the filters cooperating to filter a feed stream entering the storm sewer inlet.
