Abstract
The potential of zeolite membrane for forward osmosis operation was demonstrated. Na–ZSM–5, an aluminosilicate zeolite, membrane was used for fruit juice concentration and the purification of contaminated water with heavy metals. In these applications, Na–ZSM–5 membrane exhibited superior rejection and antifouling performances. In addition, the influence of support structure on water flux in FO operation was studied. The structure of support, namely the thickness, strongly affected water flux, indicating that the water flux through zeolite membrane will be improved by using thin supports, such as hollow fibers and anodized alumina filter.
