Abstract: A membrane wettability system including a power source configured to generate a current; a measuring device configured to measure the current; a first conducting spacer that is electrically connected to one of the measuring device and the power source; and a second conducting spacer that is electrically connected to another one of the measuring device and the power source. The first conducting spacer is physically separated from the second conducting spacer by a membrane, which is not conducting the current.

Abstract: A biofouling/biofilm removal system includes a filtration module configured to separate a permeate from a feed; a first inert electrode placed at an inlet of the filtration module; a second inert electrode placed at an outlet of the filtration module; and a power source configured to apply a current between the first and second electrodes. The inlet is configured to receive the feed and the outlet is configured to discard a concentrate, and the current applied between the first and second electrodes initiates electrochemical reactions inside the feed and along a biofilm formed in the filtration module, but not into the permeate.

Abstract: A membrane for membrane distillation processing includes a heating element configured to generate heat when an electrical current is applied to the heating element; a polymeric matrix having pores that allow a vapor to pass through, but not a liquid; and electrical contacts electrically connected to the heating element. The entire heating element is covered by an insulating material to prevent the heating element to directly interact with the liquid processed by the membrane.

Abstract: Disclosed herein are spacers having baffle designs and perforations for efficiently and effectively separating one or more membrane layers a membrane filtration system. The spacer includes a body formed at least in part by baffles that are interconnected, and the baffles define boundaries of openings or apertures through a thickness direction of the body of the spacer. Alternatively or additionally, passages or perforations may be present in the spacer layer or baffles for fluid flow there through, with the passages and baffles having a numerous different shapes and sizes.
