  • the complete solution production liquid of the device can be storage in collect tank to be ready to use, the generated disinfection solution can be used for many fields that they need sterilization instead of using any other chemical production.
  • Electrochemical water disinfection is a rarely used but convenient and highly efficient way to produce germ-free water.
  • the technique works without the addition of chemical compounds to the water to be treated, but is nevertheless based on the biotical action of various chemical Substances
  • Electrochemical water disinfection can be defined as the eradication of microorganisms by using an electric current passed through the water under treatment by means of suitable electrodes. At the phase boundary between the electrodes and the water, the electric current leads to the electrochemical production of disinfecting species from the water itself, (For example, ozone), or from species dissolved in the water (for example, chloride is oxidized to free chlorine).
  • Electrode materials for electrochemical water disinfection have been developed and optimized only in the last forty years. These are titanium electrodes with mixed oxide coatings based on iridium and/or ruthenium oxide, and doped diamond electrodes.
  • the solution can by generated by passing the original water through the electrolysis cell that content suitable metal electrode after adding the salt (sodium chloride - NaCL) to water, a DC voltage is applied between the electrodes, leading to the electrolysis of the water.

Abstract

L'invention concerne un dispositif électrochimique produisant une teneur en solution de liquide de désinfection complètement complexe (ozone, chlore actif, peroxyde d'hydrogène) (O3, CLO, H2O2) sous forme liquide. La solution peut être générée à partir des éléments existants dans l'eau eux-même par passage de l'eau originale à travers la cellule d'électrolyse qui contient l'électrode métallique appropriée après ajout de la solution de sel (chlorure de sodium - NaCl) dans de l'eau brute, une tension continue est appliquée entre les électrodes. La solution de désinfection peut être stockée dans un réservoir de collecte pour être prête à l'utilisation et peut être utilisée dans de nombreux domaines qui nécessitent une stérilisation au lieu de l'utilisation de tout autre produit chimique. La solution de produit à une très forte activité pour l'éradication de tous les micro-organismes sans qu'aucun autre produit chimique ne doive être ajouté et peut être dangereuse pour la santé humaine ou pour l'environnement ambiant.
