A portable ultrafiltration device is disclosed comprising a prefilter, pump, membrane filter cartridges, temperature sensors, pressure sensors, process interdiction and control means placed to detect temperature and pressure variations of a feed mixture being processed by the device, and means cooperating with said temperature and pressure means to interdict the operation of the device to prevent damage to the components. Provision is also made for an improved feed mixture pick-up tube comprising a sliding gate means for interdicting liquid pick-up from an oil/water feed mixture.
