ABSTRACT:
Disclosed is an apparatus for refining waste water. The apparatus includes a housing having an inlet for receiving the waste water and an outlet for delivery of refined water; a cylindrical drum member rotatably mounted in the housing, the drum member having a radial thickness t between inside and outside surfaces thereof, a multiplicity of circularly cylindrical passages being formed in the drum member, the passages having a passage diameter d of approximately 0.75 inch, at least a portion of each passage terminating with the outside surface at a corner radius r of not more than approximately 0.002 inch; a vent for admitting air into the housing; and a drive for rotating the drum to a peripheral speed of at least 1000 feet per second, whereby molecules of the waste water are physically separated from the contaminants for forming the refined water, the refined water flowing from the outlet. Also disclosed is a method for refining a liquid, including the steps of providing a housing having an inlet and an outlet for the liquid, a cylindrical drum member rotatably mounted in the housing and having a multiplicity of passages formed between inside and outside surfaces of the drum member; rotating the drum to a peripheral speed of at least 1000 feet per second; feeding the liquid into the inlet and out of the outlet of the housing; and inducing a recirculating flow of the liquid through the passages and in contact with the drum for separating impurities from the liquid.
