A first outer end cap device is coupled with the first inner end cap device; the first outer end cap device has a first port and a second port, where the first port is fluidly separate from the second port, and the first port is fluidly coupled with the inner port.

Abstract: A method for forming a ceramic membrane module system includes disposing at least one membrane within a housing, disposing at least one sealing pad adjacent to the membrane, and disposing at least one drive plate assembly adjacent to the at least one sealing pad. The method further includes coupling the at least one drive plate assembly with the housing, applying force to the sealing pad with the drive plate assembly, sealing the capillaries of a membrane end with the at least one sealing pad and forming a seal between the at least one sealing pad and the membrane, and disposing potting material into the housing without plugging more than 15% of the capillaries with the potting material.

Abstract: The invention relates to a filter device (10) serving to filter a liquid, in particular for treating water. The filter device comprises: at least two plate-shaped filter elements (12) and at least one holding element (20) for filter elements (12). According to the invention, the holding element (20) comprises a holding frame (22), a grout material (26), and an end unit (24), which is separate from the holding frame (22), wherein the grout material (26) is arranged between the filter elements (12) and the holding frame (22), such that the grout material seals the filter elements (12) against the holding frame (22), that the end unit (24) is fastened on the holding frame (22) in a liquid-tight manner, and that the holding frame (22) and the end unit (24) delimit a liquid collection chamber (40).

Abstract: A method for forming a ceramic membrane module system includes disposing at least one membrane within a housing, where the membrane has capillaries therein. The method includes sealing the first housing end and capillaries, applying force to the removable gasket with an inflatable bladder assembly or piston assembly, and disposing potting material into the housing without plugging the capillaries with the potting material.

Abstract: A method includes supplying feed water in a forward direction into a ceramic membrane treatment system at a first rate the ceramic membrane treatment system including at least one ceramic membrane (120), and determining production cycle data of the system, the production cycle data including one of more of accumulation data, feed pressure data, and time since last backflush. The method further includes determining optimal physical flux parameters based on the production cycle data and efficiency of a previous flux maintenance event, conducting a flux maintenance event including accelerated cleaning of the at least one ceramic membrane at a second rate by using a square step backwash rate based on optimal physical flux parameters. The squre step rate can be generated by ramping up pressure by a pump (220) against a closed valve (222) and a sudden openin of said valve.

Abstract: A method for removing silica includes treating feedwater with Mg at a high pH, inputting treated feedwater to an optional reactor, pumping the feedwater to a ceramic membrane in a first direction, removing precipitated solids with the ceramic membrane, and removing the precipitated solids from the ceramic membrane.

Abstract: A filtration assembly includes a membrane housing and at least one membrane fixture device disposed in the housing. Each membrane fixture device has a plurality of membrane fixture members extending from fixture device inner surface, and each membrane fixture device has membrane openings between the membrane fixture members. The filtration assembly further includes a plurality of ceramic membranes each extending from a first membrane end portion to a second membrane end portion, and each first membrane end portion is disposed in one of the membrane openings, where the membrane fixture members fixture the membranes therein.

Abstract: A filtration assembly includes at least one membrane assembly, where the membrane assembly includes a membrane and at least one end cap device. The end cap device is defined in part by a longitudinal axis and extends from a first end to a second end along the longitudinal axis. The end cap device includes an intermediate profile between the first end and the second end, and the second end has a smaller inner diameter than the first end.
