Abstract:	The effect of mass transfer in parallel-flow rectangular dialyzers with internal recycle has been investigated. In contrast to the same size device without recycle, considerable improvement in performance is achievable if one of the flow channels, either retentate phase or dialysate phase, is divided into two subchannels of same width (w/2) with one performed as the operating subchannel and the other as the reflux cochannel, which provides the increase in the fluid velocity, resulting in reduction of mass-transfer resistance. The improvement by recycle operation increases both the flow rate of liquid and reflux ratio with negligible amount of hydraulic-dissipated energy.
