Abstract: A vacuum filter includes a cylindrical filter drum 12 having both a perforate section 14 and an imperforate section 16. The drum is positioned in a tank 20 so that the imperforate section is oriented upwardly therein. A level controller is provided to maintain the level of contaminated fluid below the top of the imperforate section but above the perforate section. A filter belt 54 wrapped around the filter drum is repositioned by rotating the drum when the differential pressure between the interior and exterior of the drum reaches a predetermined value. The inlet ends 35 of the suction pipes 34 are continuously positioned at the lowest point of the drum so that the pump does not lose suction when the drum is rotated thereby facilitating continuous filtration of the contaminated fluid through the vacuum filter.

Abstract: System for separating solids from slurry containing a separable solid in a liquid carrier, such as an industrial waste. The slurry is flowed into a separation chamber positioned over a slower moving foraminous medium to effect cross-flow separation of liquid from the slurry in an initial stage and followed by separation of solids from the slurry in a second stage all the separation being effected employing a single forwardly moving filtration medium. The flow rate of liquid, the rate of travel of the foraminous medium, and the differential pressure across the foraminous medium, as established by the pressure exerted by the flowing liquid on the foraminous medium and the relative pressure underneath the foraminous medium, are controlled at different locations along the length of the separation chamber to provide optimum steady-state separation for a given waste stream.

Abstract: A filter for continuous filtering of suspension under pressure includes a pressure vessel, a shaft rotatably journalled in the pressure vessell and disc filters elements arranged on the shaft. The filter elements are composed of sectors and inlet filtrate channels in each sector are connected to axially extending channels in the shaft, one axial channel for each sector. The axial channels are connected to a filtrate valve formed to divide the filtering cycle corresponding to one rotation revolution for the filter elements in a number of filtering zones, at least one in liquid phase and one in gaseous phase. A separate filtrate outlet from the pressure vessel is connected to each filtering zone and means is controlling the difference pressure over the filtering zones independent of each other.

Pressurized air is applied along a top, longitudinal area and vacuum assist is applied along a bottom longitudinal area of the rotating filter unit. In preferred embodiments, the cylindrical unit is formed of wire spirally wound into a cylinder with spaces therebetween, there are a plurality of spaced apart bars fixed normal to the helical wire on the inner surface and rigid filter media formed of particulate material bonded in a resin matrix fills the cavities between the bars and covers the wire spirals.

Abstract: The apparatus herein provides a separation of suspended solids from a liquid containing such suspended solids. The apparatus comprises a base which supports a pan having a bottom wall, a spaced-apart pair of sidewalls extending upwardly and outwardly from the bottom wall and a spaced-apart pair of end walls extending upwardly and outwardly between the sidewalls and from the bottom wall to form an open top container. A perforated plate is secured within the pan to the sidewalls and end walls of the pan above the bottom wall to define a chamber between the bottom wall, an undersurface of the perforated plate, and the surrounding side and end walls. At least one outlet on the bottom wall of the pan is provided for introducing a vacuum to the chamber and for removing liquid from the chamber. A continuous liquid-absorbing medium transfer support extends around the pan and lies within the pan in contact with the perforated plate. The transfer support extends around the end walls of the pan to form a continuous loop around the pan. The transfer support wraps around a roller drive mechanism for providing ease of movement of the transfer support around the pan. A drive mechanism drives the rollers for moving the transfer support about the circular path around the pan. A liquid-absorbing medium comprising an industrial paper toweling having a basis weight from about 28 to about 34 pounds per ream, a caliper from about 0.013 to about 0.0145, an aged wet tensile strength from about 16 to about 25 ounces, and an aged absorption of less than 40 seconds, is positioned on the transfer support on the pan.

Abstract: Fluid supplied from a contaminant tank holding the fluid to be filtered, and delivered at a filtered fluid outlet, is supplied to a filter housing which defines a chamber therein subdivided by a perforate divider plate over which the filter paper is guided, and on which it is supported. The filter paper subdivides the chamber in an upper, or contaminant chamber, and a lower, or filtrate chamber. The lower or filtrate chamber is connected to a vacuum and suction pump. The upper portion of the housing can be raised off the filtrate paper and its support to permit movement of the filtrate paper. The contaminated fluid to be filtered is guided from the contaminant tank to the upper filter chamber, without any intermediate pumping apparatus or the like, all pumping being done by the suction and vacuum pump connected to the filtrate chamber, so that pumping equipment connected to the installation need not handle contaminated materials which may contain obstructing, abrasive or cutting particles, such as metal shavings, husks of plant material used in oil extraction processes, or the like, or toxic or biologically contaminated materials.
