ABSTRACT:
An apparatus and method for effecting mass or heat transfer between the bulk of a fluid and a transfer surface boundary layer comprises a conduit having transverse baffles spaced apart from the transfer surface such that vortex mixing is induced in fluid passed along the conduit in pulsed flow. The transfer surface may be a membrane suitable for microfiltration, ultrafiltration or pervaporation.
