  • HOCO Said base chelate called versenic acid or EDTA whose characteristic is to exchange cations for the destabilization of the water to be treated, is in the part of the protons cations of the type Silver (Ag), Zinc (Zn) and Copper (Cu) which are formed EDTA salt and whose ion exchange properties are quite active, giving as structure: catO.CO
  • Dissociation measurements were made by conductimetric methods with a TCUSEL electrode with a constant of 0.75 and in water solutions with conductivity of 200-250 psiemens and with agitation of 25 to 35 rpm.
  • the copper (Cu), Silver (Ag) and Zinc (Zn) cations tend to dissociate, leaving the molecule active, due to the enthalpy or dissociation heat they generate, once this happens, this amount of heat is enough for amino acid in the form of gel with weak bonds dissociates, creating a network for the capture of more organic material that is suspended in the water, achieving in ionic equilibrium, maintaining the action of ion capture that in turn tend to sediment due to a density difference , leaving the water with cations dissolved in the medium, which are neutralized by the action of the cations dissolved in solution and the gel-shaped amino acids that were embedded in the structure of the salts of the versenic acid (chelate).

Abstract

La présente invention repose sur le principe de micellisation que possèdent les eaux et par conséquent, le fait que le chélate se présente sous l'état de gel facilite la séparation des eaux à grumeaux plus lourds et surtout qui n'affectent pas l'environnement, étant donné qu'avec la présence du chélate dansla structure, on obtient une biodégradation, les boues obtenues ne génèrent pas de problèmes pour l'environnement, étant donné qu'elles ont tendance à se décomposer, et ainsi, elles peuvent être utilisées comme biocombustibles pour des biodigesteurs, ou pour la formation de composts ou d'engrais biologiques. L'invention concerne la modification de la structure des sels de chélate (Argent (Ag), Zinc (Zn), Cuivre (Cu)) avec incrustation d'acides aminés à haut poids moléculaire qui aident à améliorer le traitement des eaux usées à traiter sous forme de gel. Son fonctionnement est basé sur la rupture des liaisons secondaires du chélate et celles-ci à leur tour facilitent la libération des cations (Argent (Ag), Zinc (Zn), Cuivre (Cu)), ce qui a comme résultat une action sur les agents suspensibles de l'eau usée générant un système en suspension qui ultérieurement permet d'obtenir le nettoyage des eaux usées, les laissant à l'état translucide.
