Abstract: 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.

Abstract: An apparatus assembly and method for the electrolytic production of a hypochlorous (HOCl) acid solution are disclosed. A first controlled amount of water, such as tap water, a second controlled amount of an acidic solution (acetic acid or CH3COOH), and a third controlled amount of a sodium chloride (NaCl) solution, preferably from a brine solution, are mixed by injecting the same in a reaction loop comprising an electrolytic reactor configured to electrolyze the mixture into the HOCl solution. Preferably, the electrolytic reactor comprises DSA (dimensionally stable anodes). The mixture is circulated in the reaction loop until the HOCl solution is formed. The assembly can be monitored in real-time and remotely for quality control. The disinfecting solution as produced comprises 330-460 ppm HOCl at a pH between 5 and 6, preferably at a pH of 5.5, the solution being stable at least up to 6 months after being produced.

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. 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.
