| Summary: | In this study, the boundary-resistance layer model and solution-diffusion model were used to investigate the applied driving pressure force technique and the concentration driving force technique, respectively, for the production of intravenous drip solution. A 5 kD monolithic membrane coated with Al2O3 and TiO and NaCl aqueous solution as the feed solution was used. The results show that the boundary-resistance layer model diffusivity coefficient, D = 1.8�10-9 m2 sec-1 and the mass transfer coefficient, k = 1. 19- 10-4 m sec-1 which were both slightly higher than the solution-diffusion model. Applying Fick's law for the solution diffusion model, the calculated operating pressure inside the lumen was 15 kPa. Clearly, the findings suggested that the boundary-resistance layer model should be chosen for the production of pure and sterile intravenous salt solution as it provided higher diffusivity and mass transfer coefficient than the solution-diffusion model. © 2007 Asian Network for Scientific Information. |
