摘要： A device for electrolytically treating, e.g. polishing, a metal surface (11) comprises a housing (1) for making sealing contact with the surface (11) thereby to enclose an area for electropolishing, and an electrolyte chamber (5) defined within the housing (1) bounded in part by said area when the housing (1) is connected to the surface (11). A cathode (4) for contacting the electrolyte during use is also mounted within the housing (1). Said sealing contact may be made by means of a deformable seal. In operation, electrolyte is provided in the chamber (5) in contact with the surface (11) and the cathode (4), and an electric current is passed through the electrolytic cell constituted by the surface (as anode) (11), the electrolyte and the cathode (4) in order to treat the surface (11) by anodic oxidation. Preferably, the electrolyte passes through the chamber (5).

摘要： @ A porous electrically conducting filter, e.g. a membrane for filtration equipment, is cleaned by setting up an electrochemical cell comprising the membrane as a first electrode (usually the cathode), a second electrode, and an electrolyte capable of being electrolysed to a gaseous product at the first electrode. When a potential is applied across the cell, the gaseous product of electrolysis (e.g. in the form of microbubbles) cleans the surfaces of the membrane by forcing foulant material therefrom.
The electrolyte is constituted by the liquid being filtered (with the possible addition of a salt to increase electrical conductivity, if necessary) thus enabling filter cleaning to be carried out in situ whilstthe liquid being filtered continues to be passed through the filter.
