ABSTRACT:
A tubular membrane module system and method which comprise a plurality of UF modules connected in series by U-bends with an end fitting to the modules whose cross sectional flow area is substantially equal to the cross sectional flow area of the U-bends and wherein individual, longitudinal, tapered projections in the end fittings extend in the central flow passageway from the ends of each tube to minimize flow velocity changes of the streams into the central flow channel and into the end of the U-bend by maintaining a substantially constant cross sectional flow area thereby reducing expansion-contraction pressure losses.
