Abstract
A novel process for the halogenation of water comprising passing an electrolysis current through a porous, permeable anode and a cathode forming an electrodic gap with water passing therethrough, passing an aqueous solution of an alkali metal halide containing at least 25 g/l of said halide through the porous, permeable anode into the electrodic gap and controlling the hydrodynamic flow through the said anode to maintain the weight ratio of active halogen to halide in the water leaving the electrodic gap of at least 0.2, preferably near 1, and a novel electrolytic apparatus for effecting the said electrolysis and more generally suited for releasing anodically oxidated chemical species into a supporting electrolyte flowing through the cell while restraining the release of the non-oxidated species into the supporting electrolyte, that is into the effluent solution.
