Definitions

  • the goal of water treatment is to achieve a water that has the optimal properties and characteristics and is suitable for a specific use.
  • many chemical, physical and biological techniques are used.
  • the phenomenon of electrolysis is carried out in an electrolysis cell and consists in the decomposition of a solution by a electric current. This current enters the solution through two identical electrodes and of opposite electrical polarity.
  • the solution will be composed of ionizable compounds, these are divided into positive and negative ions, which migrate and accumulate in the electrodes called anode and cathode, positive and negative, respectively.
  • WATER ELECTROLISIS When a polarized continuous electric current is passed to a solution containing water (H 2 O), it is detected that from a certain potential a gas evolution begins, that potential is called decomposition and from there the increase in voltage will imply an increase in the current that passes through the cell.
  • the water decomposition voltage is the same in solutions with different chemical, physical properties.
  • the conclusion is that there is a common process in each case.
  • the only common process in all aqueous solutions is the decomposition of water, consisting of the discharge of the hydronium ions, H + , into the cathode, producing hydrogen gas, and the discharge of the hydroxyl ions, OH " , at the anode, Producing the release of oxygen gas.
  • water electrolysis generates the active compounds that produce the treatment of water purification through a chemical-physical oxidation-reduction process resulting in disinfection, clarification and Other treatment and conditioning processes such as avoiding or eliminating biological contamination or hard deposits of calcium carbonate, also helps in the coagulation and flocculation of dissolved matter in water, in short, the process of water electrolysis generates elements and compounds that activate the electrochemical properties of this allowing its improvement of chemical, biological and organoleptic quality.
  • OXIDATION By definition is the combination of an element or compound with oxygen atoms, in this reaction the oxygen atom gains electrons at the expense of the other element or compound, this process is called oxidation.
  • Oxidizing process is produced whenever an Electro-Chemical reaction exists a transfer of electrons between atoms involved or not oxygen atoms. Oxidation reactions modify the chemical properties of the compounds by altering their atomic and molecular structures.
  • ELECTROCHEMICAL ACTIVATION OF WATER Water electrolysis causes changes in the electronic structure and energy state of the chemical elements and compounds that are part of the aqueous solution, especially in the atoms and the water molecule, resulting in a large increase in its ionic activity and its chemical potentials of oxidation-reduction.
  • This increase in the electrochemical potential of the aqueous solution is considered to be an electrochemical stimulation or activation since the solution has chemical properties from electrolysis that allow it to carry out treatment, purification and conditioning processes, such as disinfection, clarification, flocculation or antifouling properties.
  • WATER CONDITIONING Another effect observed in water treated with the activation of water by electrolysis is that waters with high content of calcium and magnesium salts, hard, produce less scale or deposits of carbonates, limes, and these in case of deposits are of Amorphous type and easier removal.
