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.
