ABSTRACT:
A filtration device having a plurality of membrane modules is provided. Each of the plurality of membrane modules has first and second permeable sheets that are separated by a spacer, a first ring disposed around a perimeter of a first hole in the first permeable sheet, and a second ring disposed around a perimeter of a second hole in the second permeable sheet, the second hole in alignment with the first hole. The first ring of each of the plurality of membrane modules is in abutment with the second ring of a preceding one of each of the plurality of membrane modules so that the plurality of membrane modules are interconnected for communication therebetween. Some embodiments further provide a third sheet that disposed between successively adjacent membrane modules.
