Abstract

Método para la potabilización del agua; que comprende la filtración del agua a tratar mediante el paso de la misma a través de una membrana selectiva, constituida por una combinación de membranas de nanofiltración y membranas de ósmosis inversa, adecuada para permitir el paso de una proporción controlada de los cloruros y otras sales de molécula pequeña disueltos en el agua a tratar, Este método comprende un control de la proporción de cloruros y otras sales de molécula pequeña que atraviesan la membrana selectiva mediante: - una variación de la proporción entre las membranas de ósmosis inversa y las membranas de nanofiltración que componen dicha membrana selectiva y; - una variación de las presiones de trabajo. También contempla el tratamiento del agua potabilizada mediante un proceso electrolítico que separa el cloro de los cloruros contenidos en el agua potabilizada, con la consiguiente cloración del agua potabilizada.Method for water purification; comprising the filtration of the water to be treated by passing it through a selective membrane, consisting of a combination of nanofiltration membranes and reverse osmosis membranes, suitable to allow the passage of a controlled proportion of chlorides and other salts of small molecule dissolved in the water to be treated, This method comprises a control of the proportion of chlorides and other small molecule salts that cross the selective membrane by: - a variation of the proportion between the reverse osmosis membranes and the nanofiltration membranes which make up said selective membrane and; - a variation of working pressures. It also contemplates the treatment of potable water by means of an electrolytic process that separates chlorine from chlorides contained in drinking water, with the consequent chlorination of potable water.
