  • Filtration method for operating a filtration module with gas feed at its permeate side to prevent backflow of permeate
    Patent number: 9504964
    Abstract: A method for operation of a filtration module 4 including a housing 5 with at least one filter element 7 positioned therein, the filter element defining a first space 10 in the housing at a feeding side of its filtering surface and a second space 11 at an opposite permeate side thereof, a fluid feed 14 opening out in the first space at the feeding side of the filter element, and a permeate outlet 17 in flow communication with the second space at the permeate side of the filter element, in which the filter element is placed in an upright position. The permeate outlet is positioned at a lower end of the filter element, and a gas feed 18 is provided opening out in the second space at said permeate side of the filter element. During filtration, pressurized gas is fed into the second space.
