20080314764 | Method for the Electrochemical Decoloration of Indigo-Containing Aqueous Dispersions - The present invention relates to a process for electrochemical decolorization of indigo-containing aqueous dispersions by direct anodic oxidation on diamond-coated silicon anodes. | 12-25-2008 |
20090071845 | COATING PLANT COMPRISING AT LEAST ONE PRE-TREATMENT UNIT - A coating installation, comprising at least one apparatus for pretreating the substrates to be coated (pretreatment installation), at least one apparatus for coating the substrate with coating substances (coating apparatus), and at least one apparatus for drying and hardening the applied coating substances (hardening apparatus), wherein at least one of the pretreatment installations comprises at least one arrangement for the anodic oxidation of the deionized, i.e. fully de-mineralized, water used in the pretreatment installation with at least one electrode, the electrode having a layer ( | 03-19-2009 |
20090314656 | METHOD OF PURIFYING WATER AND APPARATUS THEREFOR - A method of purifying cooling water which requires the lowest maintenance and management cost without the need for a cumbersome cleaning operation for removing scale in an electrolytic purifying vessel by taking out the electrodes from the electrolytic purifying vessel, and an apparatus therefor are provided. In the method of purifying cooling water by applying a DC voltage across opposing electrodes while flowing water to be treated therebetween, so that ions in the water are electrically precipitated on the surfaces of the negative electrodes, thereby purifying the water to be treated, titanium is used as the positive electrodes, aluminum or an aluminum alloy is used as the negative electrodes, electric current is flown between the electrodes in an amount large enough to apply a voltage capable of dielectrically breaking down an anodically oxidized film formed on the surfaces of the positive electrodes, and the scale generated and adhered on the negative electrodes is automatically peeled off and removed by electrolytic corrosion of the negative electrodes. | 12-24-2009 |
20120037512 | ELECTRODES FOR ELECTROLYSIS OF WATER - Electrodes for electrolysis of water, for encouraging growth of algae and aerobic bacteria, for removing suspended solids from wastewater during treatment, or for rendering water sterile and potable have a concrete coating over a metallic or carbon fibre core. The coating is from 2 to 50 mm thick; preferably 5 to 25 mm thick. Preferably, a DC current passed between the immersed electrodes periodically reversed but there is no visible “rusting” at the anode if the DC current is steady. The resistive nature of the concrete tends to suppress concentrations of current upon the electrode surface. | 02-16-2012 |
20120175272 | METHOD OF STERILIZING WATER - A method of sterilizing water that includes: immersing at least one electrode unit having a negative electrode within a container and a positive electrode within the container, the positive electrode separated from and facing the negative electrode, wherein the negative electrode has a plurality of negative electrode projections thereon, and the positive electrode has a plurality of positive electrode projections thereon, each positive electrode projection arranged to face and be aligned with each negative electrode projection one by one; and, supplying direct current by at least one power supply to the electrode unit immersed under the water. | 07-12-2012 |
