Abstract: The present invention relates to a filter element and a method for manufacturing thereof. The method comprises: Providing the core tube; and rolling a membrane around the core tube. The membrane comprises a porous substrate and a filter layer on top of the porous substrate. The present invention also relates to the corresponding filter element. The filter element relating to the present invention is able to accommodate more membranes inside the same volume, resulting in high throughput and high salt rejection.

Abstract: A multistage nanofiltration (NF) system for filtering a solute from a feed solution where a downstream NF stage is more permissive to the solute than an upstream NF stage. In some examples. the nanofiltration system includes a plurality of nanofiltration stages in series, where each nanofiltration stage is more permissive to the solute than the nanofiltration stage that is immediately upstream.
