We compared two representative forward osmosis (FO) modules—spiral-wound (SW) and plate-and-frame (PF)—to provide practical information for the selection of FO element for a large-scale FO process. The FO operating performance of commercially available SW FO and PF FO was explored under different membrane area and flow rate conditions. The performance trend as a function of the membrane was obtained by adjusting the number of serially connected elements. Although SW FO and PF FO elements exhibited comparable feed pressure drops, SW FO demonstrated a significantly higher draw channel pressure drop than PF FO. Furthermore, the significant draw pressure drop in SW FO increased the draw inlet pressure, consequently limiting the number of serially connected elements. For example, the maximum number of serially connected elements for the normal operation was three elements for SW FO (45.9 m2) but nine elements for PF FO (63 m2) when the flow rate of 10 LMP was applied for feed and draw streams. Additionally, a footprint analysis indicated that SW FO module exhibited a slightly larger footprint than PF FO. Under investigated conditions, PF FO exhibited relatively better performance than SW FO. Therefore, this pilot-scale FO study highlighted the need to reduce the flow resistance of SW FO draw channel to take advantage of the high packing density of the SW element.

In PKW‐Serienlackieranlagen durchläuft jede Karosserie mehrere nasschemische Prozesseinheiten wie Reinigen, Konversionsbeschichten und Elektrotauchlackieren. Derartige Oberflächenbehandlungsprozesse müssen in Bezug auf Qualität, Kosteneinsparung und Umweltverträglichkeit immer höheren Ansprüchen genügen. Neben dem effizienten Umgang mit Energie kommt der Schonung von Wasserressourcen eine Schlüsselrolle zu, wofür sowohl die Integration bestehender als auch die Entwicklung neuer Technologien zur Prozessbadpflege wesentliche Kernelemente darstellen. In diesem Beitrag wird der Einsatz verschiedener Technologien nach dem Stand von Wissenschaft und Technik diskutiert.

“…While there have been a couple of review papers in recent years concerning the basic principles of FO [21][22][23][24], draw solutions [22,[25][26][27][28][29][30][31], applications [21,25,27,[32][33][34][35][36][37][38][39], (bio)fouling [22,25,26,30,[40][41][42][43][44][45][46], membrane fabrication [19,23,30,35,39,43,47,48], or upscaling [49,50], we, for the major part of this review, discuss the challenges of FO evidences from various literatures to prove the unreliability of the existing structural parameter approaches. In addition, we will highlight that, beyond a certain water permeability, the true bottleneck is the mechanical support of the membrane instead of the selective membrane layer.…”

Forward Osmosis: A Critical Review

The use of forward osmosis (FO) for water purification purposes has gained extensive attention in recent years. In this review, we first discuss the advantages, challenges and various applications of FO, as well as the challenges in selecting the proper draw solution for FO, after which we focus on transport limitations in FO processes. Despite recent advances in membrane development for FO, there is still room for improvement of its selective layer and support. For many applications spiral wound membrane will not suffice. Furthermore, a defect-free selective layer is a prerequisite for FO membranes to ensure low solute passage, while a support with low internal concentration polarization is necessary for a high water flux. Due to challenges affiliated to interfacial polymerization (IP) on non-planar geometries, we discuss alternative approaches to IP to form the selective layer. We also explain that, when provided with a defect-free selective layer with good rejection, the membrane support has a dominant influence on the performance of an FO membrane, which can be estimated by the structural parameter (S). We emphasize the necessity of finding a new method to determine S, but also that predominantly the thickness of the support is the major parameter that needs to be optimized.
