Method for the treatment of water containing suspended or dissolved organic and/or inorganic matter by precipitation in situ of oxygenised compounds of titanium

摘要

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.
