摘要 A hydrodynamic approach developed by a wired-membrane module forreducing the effects of concentration polarization and progressivefouling in membrane ultrafiltration, has been carried out. Thewired- membrane module is modified from a tubular-membrane module byinserting concentrically a steel rod wrapped entirely with a tightfitting wire spiral, having a diameter nearly equal to the annularspacing , as a spacer. Experiments for ultrafiltration of dextran T500aqueous solution in a wired-membrane module was carried out forvarious transmembrane pressures, feed concentrations, feed flow rates,and inclined angles of helical wire. Theoretical predictions werebased on the resistance-in-series model and confirmed qualitativelywith the experimental results. Considerable improvement of performanceis obtainable by employing a wired-membrane module rather than using atubular membrane module without or even with a steel rod insertedconcentrically.
