  • Hollow fiber module
    Patent number: 12415161
    Abstract: A hollow fiber module includes hollow fiber cartridges. A port receives a second solution to be treated in a shell side volume and another port for discharging the treated second solution. A first end cap has an inlet for a first solution and a distributer for distributing the first solution to a first end of the hollow fiber cartridges. A second end cap has a collector for collecting the treated first solution from the second end of the hollow fiber cartridges and an outlet for the treated first solution. A first connector has an inlet for the second solution and a distributer for distributing the second solution to a port of the hollow fiber cartridges. A second connector has a collector for collecting the treated second solution from the other port of the hollow fiber cartridges and an outlet for the treated second solution.

  • Anti-fouling and semi-permeable membrane
    Patent number: 12311321
    Abstract: The present invention relates to an anti-fouling, semi-permeable membrane comprising a porous support layer, a thin film composite (TFC) layer formed on a surface of the support layer, and a cross-linked polyvinyl alcohol (PVA) layer formed on top of the TFC layer, wherein the cross-linked PVA layer is the reaction product of PVA and a cross-linking agent, said cross-linking agent being a polybasic acid comprising three or more acid groups or precursors thereof. The obtained membrane shows a high water flux and a low roughness suitable for an effective membrane notable for feed solution having a tendency of fouling the membrane.
