International Classification:

C02F 9/02

US Classification:

210163, 210266, 210282

Abstract:

A method and apparatus for separating oil and debris from urban water run-off, the apparatus being made up of a chamber which is mounted in a storm drain system and has an inner basin with a tilted wire wedge wire screen filter in the path of flow of the run-off, an organic absorber floats on the water as it is collected in the basin, and a discharge plate has a series of slots which are sized to regulate the flow rate of discharge of the water from the basin for removal through an outlet at the lower end of the chamber. The method and apparatus are conformable for use with existing storm drain systems along curbs or gutters as well as parking lots, runways and the like.

International Classification:

A01K 6300

US Classification:

119219

Abstract:

An apparatus and method for continuously cleaning fish screens located in wetland diversions which are subject to tidal fluctuations, as well as in river and stream diversions, provides a brush or wiper member attached to a flotation device to clean the fish screen continuously. The apparatus can utilize conventional power where available, or utilize available and renewable energy sources such as tidal influx, solar or wind power, as well as gravity water flow.
