Abstract
An apparatus is provided for removing a floating pollutant such as oil from a liquid such as water by passing the oil and water over the top of a weir and allowing the oil and water to fall between a side of the weir and a baffle closely adjacent to the weir and extending into a pool at the bottom of the weir. Oil collects in a quiet area adjacent the baffle while the water passes over a subsequent weir to removal.
