Abstract
This work investigated the effects of reactant concentrations and synthesis periods on in situ deposition of zeolite membranes on glass hollow fibers. The separation performances of the zeolite membranes in forward osmosis applications were studied based on pure water fluxes and reverse solutes. The reactant concentration of 0.66 M enabled zeolite membrane deposited onto glass hollow fiber to give a water flux of 4.50 L m−2 hr−1 with reverse solute of 0.05 kg m−2 hr−1. When the deposition time was reduced to 12 h and 18 h, water fluxes increased to 62.25 and 71.92 L m−2 hr−1, respectively.
