Abstract

See full text

A biological particle filter has an upper body with an interior chamber for receiving a suspension to be filtered, the upper body having a central axis and a lower end with a bottom surface lying in a tilted plane forming an angle of between about 75.degree. and about 85.degree. with the central axis. A lower body has a chamber for receiving the lower end and bottom surface of the upper body with an upwardly facing annular support surface. The upwardly facing support surface lies in a plane parallel with said bottom surface. A passage extends downwardly below the screen for carrying away filtered suspension. An air inlet passage extends generally radially in at an upper end of the downwardly extending passage. A filter screen is between the bottom surface and the upwardly facing support surface and lies in a plane parallel with the tilted plane of the bottom surface, the tilted plane and the air passage promoting flow of filtered suspension through and away from the filter.
