NUEVO FLOCULANTE PARA EL TRATAMIENTO DEL AGUA RESIDUAL NEW FLOCULANT FOR THE RESIDUAL WATER TREATMENT
DESCRIPCIÓNDESCRIPTION
OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a un nuevo floculante para el tratamiento de aguas residuales, el cual aporta esenciales características de novedad y notables ventajas con respecto a los sistemas utilizados en el estado actual de la técnica para este mismo fin.The present invention relates to a new flocculant for the treatment of wastewater, which provides essential novelty characteristics and notable advantages over the systems used in the current state of the art for this same purpose.
En particular, el nuevo floculante de la invención es utilizable en el tratamiento de las aguas orgánicas e inorgánicas que se producen en los procesos derivados de las actividades de la construcción y en cualquier otro tipo de industrias .In particular, the new flocculant of the invention is usable in the treatment of organic and inorganic waters that are produced in the processes derived from construction activities and in any other type of industries.
El campo de la invención se encuentra comprendido, lógicamente, dentro de aquellas industrias dedicadas al tratamiento de aguas residuales.The field of the invention is logically included within those industries dedicated to wastewater treatment.
ANTECEDENTES DE LOA INVENCIÓNBACKGROUND OF THE INVENTION
Los floculantes se clasifican en orgánicos e inorgánicos. En el caso de los floculantes orgánicos, su estructura principal cuenta con macromoléculas orgánicas que provocan materias de coagulación de gran tamaño, mientras que el agua y la escoria producidas con el tratamiento están dotadas de un carácter viscoso en virtud de lo cual, al utilizarse posteriormente en un proceso de deshidratación, se pueden presentar determinados problemas, además de que la sustancia orgánica puede contaminar el ambiente micróbico. Por otro lado, se ha constatado que los floculantes orgánicos alteran sustancial ente el pH del agua tratada, con lo que el agua requiere posteriormente la aplicación de un proceso de neutralización con la utilización de sustancias químicas, para lo que necesitará de un tiempo de reposo en el interior del depósito de neutralización, de donde se desprende que la utilización de floculantes orgánicos para el tratamiento del flujo continuo del agua residual no resulta adecuada en absoluto.Flocculants are classified as organic and inorganic. In the case of organic flocculants, its main structure has organic macromolecules that cause coagulation materials of large size, while the water and slag produced with the treatment are endowed with a viscous character by virtue of which, when subsequently used In a dehydration process, certain problems can occur, in addition to the organic substance can contaminate the microbic environment. On the other hand, it has been found that organic flocculants substantially alter the pH of the treated water, so the water subsequently requires the application of a neutralization process with the use of chemical substances, for which it will need a rest time inside the neutralization tank, from which it follows that the use of organic flocculants for the treatment of the continuous flow of wastewater is not adequate at all.
En lo que se refiere a los floculantes inorgánicos, hay que señalar que utilizan principalmente la fuerza coagulante derivada del ion de aluminio y que su segregatividad del agua tratada es buena, a pesar de que su capacidad de coagulación es sensiblemente inferior a la de los floculantes orgánicos, habiéndose podido observar que los floculantes inorgánicos reducen el valor del pH, siendo necesario en consecuencia la utilización de algún procedimiento de neutralización con anterioridad a su evacuación hacia la red de alcantarillado.As regards inorganic flocculants, it should be noted that they mainly use the coagulant force derived from aluminum ion and that their segregativity of the treated water is good, although their coagulation capacity is significantly lower than that of the flocculants organic, having been able to observe that inorganic flocculants reduce the pH value, being necessary therefore the use of some neutralization procedure prior to its evacuation to the sewage network.
A la vista de cuanto antecede, resulta evidente que la solución a la problemática planteada seria la de poder contar con un floculante que reuniera las características adecuadas para poner solución a tal problemática, y que a la vez dicho floculante no pudiera ser alterado por las sustancias orgánicas e inorgánicas existentes en el agua residual, evitándose también el hecho de que se produzcan coagulaciones del mismo tamaño y fuerza que las verificadas en el floculante orgánico con poca adición del mismo, siendo igualmente deseable que este floculante esté dotado de un efecto sedimentario positivo y que no requiera tratamiento de neutralización antes de la evacuación del agua hacia la red de alcantarillado. Hasta el momento no se tiene conocimiento de la existencia de un floculante que reúna las características detalladas más arriba como deseables, cuya consecución constituye precisamente el principal objeto de la presente invención.In view of the foregoing, it is clear that the solution to the problem posed would be to have a flocculant that would meet the appropriate characteristics to solve this problem, and that at the same time the flocculant could not be altered by the substances organic and inorganic existing in the wastewater, also avoiding the fact that coagulations of the same size and strength occur as those verified in the organic flocculant with little addition thereof, it being equally desirable that this flocculant be endowed with a positive sedimentary effect and that does not require neutralization treatment before the evacuation of the water to the sewer system. So far there is no knowledge of the existence of a flocculant that meets the characteristics detailed above as desirable, the achievement of which is precisely the main object of the present invention.
