Abstract

A hybrid filter system (10) and a method for filtering process fluid utilizing a backwash (14) containment vessel (12). Tube sheet assemblies (14) designed to hold disposable or backwashable filter elements (20) are utilized to secure either type of filter elements in the backwash containment vessel (12). The tube sheet assemblies (14) are removably mounted in the backwash containment vessel (12), and may be easily swapped for a given filtering application. The hybrid filter system (20) utilizes a backwash containment vessel (12) in conjunction with either disposable filter elements or backwashable filter elements depending upon process flow parameters.
