This study investigated the effects of initial feed (20-50 L/min) and draw flowrates (2-5 on 8040 spiral-wound FO element performances in serial configuration for a forward osmosis reverse (FO-RO) hybrid system employing single element-based tests.Average J w,ave values varying were found to be 20.93, 19.38 18.71 LMH at E1, E2 E3 (first, second third elements configuration), respectively, with averaged diluted concentrations 12.55, 7.88 5.77 g/L (initial conc.= 35 g/L).The stream dilution...
We propose the noncontact measurement of elasticity by using an optical fiber heterodyne interferometer and laser ultrasonics. The surface acoustic wave (SAW), that is generated pulse irradiation on sample propagating along surface, optically monitored without taking any contact with sample. By several measurements changing relative distance between excitation points, phase velocity SAW was calculated from which could be obtained. This proposed method experimentally evaluated PDMS samples...
