Patent number: 11572291Abstract: A membrane filter apparatus for splitting a feed into filtrate and retentate is provided. The apparatus comprises a body chamber, a feed inlet disposed on the body chamber, a retentate outlet located in the body chamber, a feed distribution tube connected to the feed inlet, and a filter assembly having a filter. The feed distribution tube has a length sufficient to cause the feed to enter the body chamber at a feed distance from the filter assembly of no greater than 50% of a total length of the body chamber. The feed flows across the filter in a direction parallel to a surface of the filter assembly. The filtrate passes through the filter assembly and the retentate flows through the body chamber in a direction antiparallel to the feed flow through the feed distribution tube and out through the retentate outlet.Type: GrantFiled: February 17, 2021Date of Patent: February 7, 2023Assignee: King Abdulaziz UniversityInventors: Hani Abdullah Abulkhair, Iqbal Ahmed Moujdin, Mohammad S.

Patent number: 11220762Abstract: A multi-angle spinneret for forming hollow fibers is provided. The multi-angle spinneret includes a body defining a dope chamber, a bore needle channel, and multiple dope channels being oriented at a minimum of two distinct dope channel angles relative to the dope chamber. The body includes a bore needle disposed in the bore needle channel and oriented substantially perpendicular relative to the dope chamber. The bore needle extends though the dope chamber, such that a bore fluid flow through the bore needle is kept separate from a dope flow through the dope channels. A bore fluid outlet is positioned within a dope outlet of the dope chamber, such that a bore fluid flow out of the bore fluid outlet is substantially coaxial with and substantially centered within a dope flow out of the dope outlet.Type: GrantFiled: August 30, 2021Date of Patent: January 11, 2022Assignee: King Abdulaziz UniversityInventors: Iqbal Ahmed Moujdin, Rosli Bin Mohd Yunus
