Abstract: A ceramic membrane including a feed flow inlet, a retentate flow outlet, a permeate flow outlet, a membrane interface portion. The membrane interface portion include a feed flow channel fluidly coupled to the feed flow inlet and to the retentate flow outlet and permeate flow channel fluidly coupled to the retentate flow outlet, wherein the membrane interface portion is operable to allow for fluid communication between the feed flow channels and the permeate flow channels through a membrane portion, and wherein the ceramic membrane has an open porosity of at least 10%. Also provided is a process for preparing the ceramic membrane by additive manufacture.

Abstract: A ceramic membrane, and a process for producing a ceramic membrane. In the process for the production of a ceramic membrane the ceramic membrane is produced by additive manufacturing. The ceramic membrane comprises a membrane portion comprising pores. A nano-and/or micro-particle is formed in-situ from a nano- and/or micro-particle precursor during the additive manufacturing process and/or post-processing step. The ceramic membrane comprises the in-situ formed nano- and/or micro-particle, or residue thereof, arranged within the pores of the membrane portion. Also described is a water treatment module including the ceramic membrane.

Abstract: A baffle for a membrane device. The membrane device includes a membrane, a feed flow inlet, and a feed flow outlet, such as for water filtration. The baffle includes a proximal end and a distal end, wherein the baffle is operable to extend along at least a portion of the membrane so that the proximal end is toward the feed flow inlet of the membrane device and the distal end is toward the feed outlet of the membrane device. The baffle includes a first geometry portion and a second geometry portion. The first geometry portion includes a higher aspect ratio than the second geometry portion and the first geometry portion is arranged closer to the proximal end of the baffle than the second geometry portion. Also described is a method of producing the baffle and a membrane device containing the baffle.

Abstract: The invention is a reorganization planning system having a reorganization planner, a database management system, and one or more database files. The reorganization planner communicates with the database management system and the one or more database files to develop a reorganization plan for reorganizing one or more objects of the database files. According to various embodiments, the reorganization planner also provides for in-place object reorganization and application of a benefit threshold. The benefit threshold limits the number of objects recommended for reorganization.
