Abstract
(EN)

The present invention discloses a method and apparatus for separating particles and dissolved matter from an untreated fluid stream. Specifically, the present invention includes a first pressure source which transports untreated fluid or contaminated aqueous fluid into a separator annulus with a filter element disposed therein. The untreated fluid is placed under appropriate pressure sufficient to produce turbulent flow, increased particle kinetics and/or cavitation allowing the desired fluid to penetrate and pass into and through the filter media. The treated fluid is then transported to a collection tank. The contaminant matter retained by the filter media may be removed by the nearly instantaneous reverse pressurization of the separator annulus by a second pressure source thereby removing the contaminant particles away from contact with the filter media, and which may then be transported to a waste collection tank or a separator for further treatment.
