Patent number: 9950299Abstract: The invention relates to an apparatus and a process for the treatment of an incoming fluid, comprising: a bottom part connecting a common feed stream to individual membrane filter modules through a tailor made connecting piece; a top part connecting individual membrane filter modules to a common retentate stream through a tailor made connecting piece. According to the invention the apparatus is assembled out of tailor-made parts with the object to reduce material costs and labor costs, and the part are made such that footprint of the contraption is minimized. Furthermore, the individual parts form a sub-unit with such dimensions that multiple sub-units can be combined into one main unit, without the need to execute any alterations to the sub-units in terms of sizing, by which means modularity and scalability is introduced into the main units.Type: GrantFiled: October 19, 2010Date of Patent: April 24, 2018Assignee: X-Flow B.V.Inventors: Rob Borgerink, Derk Rudolf Journeé, Robert Martinua Van Opdorp, Bastiaan Blankert
