Method for the treatment of water containing suspended or dissolved organic and/or inorganic matter by precipitation in situ of oxygenised compounds of titanium (Machine-translation by Google Translate, not legally binding)

The method involves (a) mixing the water to be treated with a solution which is made up of a compound of titanium selected from a compound of Ti (IV), a compound of Ti (III), and their mixtures, keeping the pH of the mixture at a value suitable for the precipitation in situ of the titanium in the fo...

Zusammenfassung:The method involves (a) mixing the water to be treated with a solution which is made up of a compound of titanium selected from a compound of Ti (IV), a compound of Ti (III), and their mixtures, keeping the pH of the mixture at a value suitable for the precipitation in situ of the titanium in the form of an oxygenised compound of titanium (b) shake the mixture resulting from stage (a) for the period of time required to allow he formation of stable floccules and (c) separate the flocculated solid matter. This method facilitates the separation of the suspended matter by processes of coagulation-flocculation and the dissolved matter by processes of adsorption and ionic exchange. Of interest for decontaminating waste water. (Machine-translation by Google Translate, not legally binding) El método comprende (a) mezclar el agua a tratar con una disolución que comprende un compuesto de titanio seleccionado entre un compuesto de Ti (IV), un compuesto de Ti (III), y sus mezclas, manteniendo el pH de la mezcla en un valor adecuado para la precipitación in situ del titanio en forma de un compuesto oxigenado de titanio; (b) agitar la mezcla resultante de la etapa (a) durante el periodo de tiempo necesario para permitir la formación de flóculos estables; y (c) separar la materia sólida floculada. Este método permite separar la materia suspendida mediante procesos de coagulación-floculación y la materia disuelta mediante procesos de adsorción e intercambio iónico. De interés en la descontaminación de aguas residuales.
