Abstract
Acoustic pressure shock waves are applied to a membrane in a fluid to prevent attachment of or dislodge biological or solid matter for membrane cleaning or desalination with a membrane.
Claims20
A method of using a porous filtration membrane in a fluid comprising generating acoustic pressure shock waves wherein each cycle of an acoustic pressure shock wave includes a compressive phase and a tensile phase and applying the acoustic pressure shock waves through the fluid to the membrane to prevent or dislodge attachment of biological or solid matter in the fluid to the membrane.
A system for using a porous filtration membrane in a fluid comprising a fluid containment, an inlet to the containment for fluid to be filtered to enter the containment, a porous membrane positioned in the containment, one or more shock wave devices configured to generate acoustic pressure shock waves wherein each cycle of an acoustic pressure shock wave includes a compressive phase and a tensile phase and the one or more shock wave devices are oriented to apply shock waves to the membrane and a filtered fluid outlet from the containment for filtered fluid to exit the containment.
