Abstract : The patent discloses an oil-water separating device using the wall attachment effect for separating oil from an oil-water mixture in a continuous manner. The device is comprised of an oil-water mixture inlet nozzle delivering the mixture into a bounded region inside the separator to form a mixture jet which attaches to one wall creating a separation bubble in the bounded region. The bounded region is provided by a cavity formed by two or more plates joined together with an oil collecting chamber provided on top of the bounded region by an additional plate. The oil is captured in the bounded region by the separation bubble and flows into the oil collecting chamber through connecting holes. The oil in the collecting chamber is transferred by an oil outlet, either by siphoning or by means of a metering pump to an oil storage tank.
