Abstract
The data presented in this paper are produced as part of the original research article entitled “Thin-film composite membrane on a compacted woven backing fabric for pressure assisted osmosis” (Sahebi et al., 2017). This article describes how to fabricate a defect free membrane for forward osmosis (FO) and pressure assisted osmosis (PAO) on the woven mesh backing fabric support. Casting polymer on backing fabric support may limit the interfacial polyemirization due to wrinkled membrane surface. This paper presents data obtained from two different backing fabrics used as support for fabrication of thin film composite FO membrane. Backing fabric support were woven polyester mesh with different opening size. The data include the characterization of the intrinsic properties of the membrane samples, SEM and their performance under FO process. The structural parameters (S value) of the substrate were computed from thickness and porosity of the substrates. Thin film composite (TFC) membrane achieved a water flux of 8.1 L m2 h−1 in FO process and 37 L m2 h−1 using 0.5 M NaCl as draw solution (DS) and deionised (DI) water as the feed solution (FS) when applied hydraulic pressure was 10 bar.
Highlights
Casting membrane for forward osmosis (FO) and RO in a large scaleThis method has been chosen in commercial scale in order to limit the polymer solution bleeding through the woven mesh fabric in the CTA-FO membrane which otherwise leads to defect points across the FO membrane substrate due to trapped air bubbles [1,5]
Fabricating robust thin film composite membranes reinforced on woven mesh backing fabric support for pressure assisted and forward osmosis: A dataset
This paper presents data obtained from two different backing fabrics used as support for fabrication of thin film composite forward osmosis (FO) membrane
Summary
This method has been chosen in commercial scale in order to limit the polymer solution bleeding through the woven mesh fabric in the CTA-FO membrane which otherwise leads to defect points across the FO membrane substrate due to trapped air bubbles [1,5]. In method 2, polymer solution first is casted on the rotating drum the porous fabric will be pulled from the top whereas in RO style membrane fabrication (method 1) polymer solution directly is poured and casted on the nonwoven thick fabric
