Abstract. Currently existing construction of roll ultrafiltration module (RUM) is characterized by lowering of the longitudinal flowspeed of spreaded fluid throughout the whole length of membrane element's (ME) pressure channel. During the work of RUM the particles ‘pollution concentration continuously growing from the entering to pressure channel till the exit from it. That is why the stabilization of longitudinal flowspeed of spreaded fluid throughout the whole length of ME's pressure channel with continuous dumping of a part of polluted fluid will contribute to increasing the technical characteristics of RUM in time. The construction of RUM offered allows supporting relatively stable longitudinal flowspeed of spreaded fluid throughout the whole length of ME's pressure channel.
Keywords: concentration, ultrafiltration, roll module, membrane element.
