Abstract: An electrode (10) is disclosed in which a first layer (30) of TiOx with a porosity in the range 0-3% is present on at least one surface of an electrode substrate (20), a second layer (40) of TiOx with a porosity of greater than 3 and up to 20% is present on the first layer (30) of TiOx. An electro-catalytic layer (50) is present on the second layer (40) of TiOx. x is in the range 1-2 for the first (30) and second layer (40) of TiOx. A process for the manufacture of the electrode (10) is disclosed as are uses thereof.

Abstract: The invention relates to a process of abatement of the organic content of a depleted brine coming from epoxy compound production involving a vapour stripping step and a mineralisation with hypochlorite in two steps, at distinct pH and temperature conditions.

Abstract: An on-site apparatus and method for preparing aqueous cleaning compositions, including an electrolytic cell for producing and dispensing chlorine and sodium hydroxide for use in various cleaning and/or sanitizing formulations at the point of use.

Abstract: The present invention pertains to electrolytic diaphragm cells, particularly for the electrolysis of brine to produce chlorine and caustic. The innovation resides generally in the discovery that electrolytic cell operation can be desirably enhanced by compressing the diaphragm between anode and cathode. This compression of the diaphragm reduces the diaphragm thickness from an original thickness, e.g., from an original thickness of a diaphragm freshly deposited on a cathode. The reduced thickness of the diaphragm provides for cell operation that is less than zero gap operation. By maintaining the diaphragm under compression and in a reduced thickness, the cell operates with a narrower interelectrode gap and consequently at a desirably reduced cell voltage.
