摘要： A system for the confinement of pollutants on water surfaces until collected or chemically dispersed. The system effects its confining action by generating a curtain or barrier of air bubbles which at the surface of the water form a series of overlapping aerated water hills capable of blocking the passage of a pollutant, such as oil film, therethrough. The system is designed to enable it to provide a continuous barrier of aerated water hills over long period of use and even though it may be installed on harbor and waterway bottoms where silty conditions prevail. This is accomplished by a pipe for supplying compressed gas to an outlet comprising a nozzle plate having an orifice of a size to allow a metered amount of air to pass with a check valve located downstream of the nozzle plate.
