AB Direct membrane filtration (DMF) has emerged as anattractive option to treat municipal wastewater; however, thistechnology suffers from severe membrane fouling. In this paper, arotating hollow fiber module for enhancing the fouling control isproposed. The experimental study was conducted at lab scale, filteringa primary settled municipal wastewater. The effectiveness of thistechnology coupled with physicochemical pretreatment was alsoevaluated. Results showed the existence of a threshold permeate flux(32−36 L/h·m 2), below which the shear rates exerted by membranerotation prevented supramicron size particle deposition, regardless ofthe application of physicochemical pretreatment, even at lowrotational speeds (w = 120 rpm). At higher fluxes (40−48 L/h·m 2),the rotational speed had to be increased to 340 rpm to achievesustainable conditions. Even when applying physicochemical pretreat-ment, the internal residual fouling was found to be the main fouling contribution, probably associated with the submicronparticles
