    摘要: An apparatus and method for separating, harvesting and primary dewatering microalgae biomass from a microalgae solution by destabilization thereof with addition of kinetic energy thereto is disclosed. The method to overcome the energetic barrier preventing a fluid-solid separation comprises injecting the microalgae solution in an electrolytic system comprising an electrocoagulation reactor generally comprising an anode module and a cathode module, the anodes and the cathode(s) being adapted to be electrically connected to perform electrolysis, thus separating, harvesting and primary dewatering microalgae biomass. Such process is generally achieved by providing a DC electric current, between the anodes and the cathode(s), to perform the separation of the biomass in the solution, in preparation the following process steps of for liquid/solid separation and primary dewatering.

    摘要: An electrolytic system for treating wastewater by electrocoagulation, electroflotation or a combination of both is disclosed. The electrolytic system comprises a first electrolytic reactor adapted for receiving the wastewater to be treated, the first electrolytic reactor comprising at least one cathode and at least one anode to perform a first electrolytic treatment for eliminating organic matter and calcium present in the wastewater that impact on nucleation of struvite; and a second electrolytic reactor downwardly connected to the first electrolytic reactor, the second electrolytic reactor comprising at least one cathode and at least one magnesium anode to perform a second electrolytic treatment for producing Mg2+ ions which react with NH4+ and orthophosphates from said wastewater to form a struvite precipitate. The electrolytic system allows eliminating simultaneously orthophosphate and ammonium from the wastewater while enabling the production of struvite.

    摘要: 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. Advantageouslly, by having the outlet extending upwardly above the electrodes, any dead zone typically found on electrodes at the level of the outlet are eliminated, increaing as such the useful surface area of the electrodes spanning the entire length of the electrolytic chamber.

    摘要: 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.

    摘要: An electrolytic assembly and a method for the bacterial disinfection of water or wastewater is disclosed. Water circulating in cooling towers such as those that discharge heat from air conditioning; ships' ballast water; or wastewater with a dryness varying from 0.01 to 3%; can be treated. The assembly comprises one or more electrolytic units comprising at least one Dimensionnally Stable Anode commonly known as DSA, or a Boron Doped Diamond anode, also named BDD anode. The electrolytic treatment at least partially kill the bacteria present in the water. It has been shown that the electrolytic treatment breaks the cell membrane of bacteria present in the water. The treatment is particularly adapted for eliminating Legionella and others microorganisms, such as E. coli.

    摘要: 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.
