Abstract: Filter pads, which are made inherently stable by binders and by removal of the binders can be converted in packings to be maintained under substantially constant surface pressure between rigid filter brackets, are produced first as molded bodies from a suspension of filter aids in liquid by depositing granular, fibrous, or fiber-containing filter aids or mixtures of those filter aids in a casting mold, there being used high rates of flow while avoiding turbulences, and adding binders to the suspension so that the molded body can be stabilized by activation of the binder while drying. It is possible in this process also to manufacture multi-layered filter pads, it having been surprisingly found in those multi-layered filter pads that the layer assembly is kept intact during the filtration even in the filter packing that no longer contains binders. The filter pads or the filter packings produced therefrom according to the invention can, when used, and after reflushing and regeneration operations, finally be utilized, after being replaced, as filter aids in the deposit filtration process.

Abstract: A pressure filter for separating a liquor from mud liquor slurry and for concentrating a filter cake as a heavy slurry discharge comprising a tank having a ring of filter elements supported by a plate which separates the filter tank from a filtrate chamber. The feed enters the tank under pressure through an enlarged feed cylinder tube located in the center of the ring of filter elements. In the backwashing mode of operation the feed rate is maintained or increased to assist in displacing filter cake from the filter elements.

Abstract: A method and apparatus for agitating and scrubbing a filter bed in which a tubular arm is disposed in the bed near the top thereof and is adapted for rotation on a vertical central axis. The arm has nozzles extending from opposite sides thereon on respective sides of the center and is caused to rotate in the filter bed by the supply of air under pressure through the arm to the nozzles. Other nozzles can be mounted on the ends of the arm to treat the filter bed outwardly from the ends of the arm. The air supplied to the nozzles may be enriched with oxygen. The filter bed is preferably backwashed by upward flow of water therethrough simultaneously with the agitation and scrubbing of the upper portion thereof with the air jets.

Abstract: The disclosed filter comprises a filter housing having a generally conical downwardly tapering bottom wall and a closed top wall. A generally conical filter medium is mounted in the housing so as to partition the housing into upper and lower compartments. Rather than being conical, the filter medium may be in the shape of a downwardly tapering inverted pyramid, having any desired number of sides, with its apex down and its base at the top of the filter medium. During the normal filtering operation, paint or some other liquid is supplied under pressure to a lower opening at the lower end of the conical bottom wall. The paint or other liquid passes upwardly through the filter medium which removes any foreign particles. The filtered liquid or filtrate then passes out of the upper compartment through an outlet pipe extending from the lower portion of the upper compartment through the top wall and out of the housing. A control valve is provided to disconnect the paint supply from the lower opening and to connect the lower opening to a drain. This valve is actuated when the filter medium is to be cleaned. To clean the filter medium, a solvent is supplied to spray means in the upper compartment, so that the solvent will pass through the filter medium into the lower compartment and out of the housing through the control valve to the drain. The paint and the solvent may be supplied by a paint supply pump and a solvent supply pump. A second control valve may be connected into the outlet pipe. Preferably, a wash cycle is initiated automatically by a pressure sensor which is operated by excess paint pressure due to clogging of the filter medium. The pressure sensor causes the operation of a control system which initiates a wash cycle so as to stop the paint supply pump, actuate the first control valve, close the second valve, and start the solvent supply pump. The control system preferably includes a timer for terminating the wash cycle so as to stop the solvent supply pump, open the second control valve, deactuate the first control valve, and start the paint supply pump.

Abstract: 919,470. Filters. BERLINE J. R. A. July 25, 1961 [July 27, 1960], No. 26925/61. Class 46. In a cluster of filtering tubes each tube 1 has a flared upper end supported by an annular rubber or plastic gasket 18 in a supporting plate 16 and is held under adjustable pressure from bolts 21 in washers 20 which, through tube retaining rings 19, exert pressure against a plurality of tubes simultaneously. Each tube consists of a core 2 of perforated sheet metal or expanded metal and a sheath 5 of metal or synethetic fabric e.g. " Terylene " Registered Trade Mark and is rigidly united with an endpiece 4 which is secured to a metal lattice 6 by a stud 8. For cleaning, filtrate accumulated in a dome of the filter housing is counterstreamed by the pressure of gas in the dome, or introduced thereto, and this with the help of the resultant vibration of the tubes, causes the filter cake on the outer face of the filter fabric to be removed. Alternatively, steam under pressure may be used to clean the tubes. The washers may be circular or star-shaped, each point of a star being assigned to a tube.

Abstract: A rotary disc filter is provided with an integrated backwash and chemical cleaning system. In one mode of operation, backwash is directed through a control valve to one or more nozzles for spraying the backwash onto the filter media forming a part of a rotary disc filter. In a second mode, a chemical cleaning mode, the pump directs backwash through an eductor that induces a chemical into the inductor which is mixed with the backwash to form a backwash-chemical mixture that is sprayed onto the filter media. A control system is used in conjunction with the backwash and cleaning systems to monitor process information and/or filter media properties and to determine when to perform backwashes and regenerative cleanings in order to optimize the performance of the filter system.

Abstract: The present disclosure provides a method for flushing particle bearing filter beds located in a circuit or linear water treatment plant for sterilization and decontamination of the filter beds. The filter can be charged with a chlorine-oxide-containing, chlorine-dioxide-containing, halogen-containing, and/or peroxide-containing aqueous solution. A solution acts on the deposits of the particle-type filter bed such that the bed can be subsequently flushed with water and/or an aqueous medium for removal of the process caused reaction product and any residual chlorine oxides or halogens or peroxides.
