Abstract
The effect of the filter design on in vitro pressure drop and the performance of three different types of polyacrylonitrile (PAN) CAVH filters were studied. Two effects of the filter design were examined. (1) the length of hollow fibers in the housing, (2) the diameter of hollow fibers in the housing, were examined. The lowest pressure drop (13mmHg at QB=50ml/min) was obtained with the type C filter which is of a short length and wide diameter hollow fiber. High UFR (QF=17ml/min.) was obtained at a low pressure drop(30mmHg) with the type C filter. A good compatability of QF between experimental data and theoretical hypothesis using the gel-polarization model was obtained at low QB and high THP.
