Abstract: An electrolytic assembly for the bacterial disinfection of water is disclosed. For example, water circulating in cooling towers such as those that discharge heat from air conditioning can be treated, or wastewater with a dryness varying from 0.01 to 3 %. The assembly comprises electrolytic unit(s) comprising at least one Dimensionnally Stable Anode commonly known as DSA. A method for the bacterial disinfection of water, such as water circulating within a cooling tower is also disclosed. The method comprising the steps of a) injecting water into an electrolytic unit comprising at least one DSA, the water having circulated in a cooling tower prior to be injected into the electrolytic unit; b) performing an electrolytic treatment of the water circulating into the electrolytic unit for at least partially kill bacteria present in the water; and c) optionally, re-injecting the water once treated into the cooling tower. The treatment is particularly adapted for eliminating Legionella and/or E. coli.

Abstract: An electrolytic reactor for the electrolytic treatment of a fluid is disclosed. The reactor comprises an electrolytic chamber, an electrode cartridge comprising an electrode assembly longitudinally extending from a crown section configured to operatively seal the electrolytic chamber when the electrode assembly is inserted in the electrolytic chamber; an inlet extending perpendicularly to a vertical longitudinal axis defined by the electrolytic chamber; and an outlet extending through the crown section along the vertical longitudinal axis defined by the electrolytic chamber, the outlet being configured to be in fluid communication with the electrolytic chamber when the electrolytic chamber is sealed by the crown section. Advantageously, by having the outlet extending upwardly above the electrodes, any dead zone typically found on electrodes at the level of the outlet are eliminated, increasing as such the useful surface area of the electrodes spanning the entire length of the electrolytic chamber.

Abstract: A novel magnesium-based alloy is described. The alloy is particularly suitable for the construction of electrodes, especially anodes, that can be used for an electrochemical process, such as the synthesis of struvite. The magnesium-based alloy is an AZXY alloy in which A is aluminium and Z is zinc, X represents the content, expressed in wt. %, of the first element, and Y the content, expressed in wt. %, of the second element. The AZXY alloy according to the invention has 2%≤X≤4% and 0.5%≤Y≤2%, and an iron (Fe) content of less than 0.005%, and preferably less than 0.003%. The anodes constituted by this novel alloy have a much slower corrosion speed and improved performances compared to existing anodes. An electrode cartridge comprising said alloy and suitable for being inserted into an electrolytic reactor so as to form, once assembled, an electrocoagulation unit, is also described.

Abstract: An electrolytic reactor and process for decontaminating wastewater containing emerging contaminants, such as medicament residues or per- and polyfluoroalkyl substances (PFAS) are disclosed. The contaminated wastewater is circulated through one or several reactors for electro-oxidizing and degrading the contaminants. Each reactor comprises an enclosure, an electrode assembly comprising first and second current distribution circuits, a first group of N electrodes connected to the first current distribution circuit, and a second group of N electrodes connected to the second current distribution circuit. According to the polarity of the current provided to the electrodes, the electrodes of the first group form anodes whereas the electrodes of the second group forms cathodes, and vice versa. The electrodes are preferably dimensionally stable anodes (DSA). The reactor and process described herein allow removal of multiple emerging contaminants simultaneously, in addition to reducing the carbon footprint through lower power consumption.
