| titleOfInvention | PROCESS FOR POTABILIZATION |
| abstract | The invention relates to a process for the potabilization of an aqueous solution having suspended solids, containing a coagulation-flocculation step which comprises: a) a step of adding coagulants in the aqueous solution to be treated, followed; b) a stirring step of the aqueous solution thus added; c) a step of separating the coagulated solids by decantation or flotation; d) a step of recovering a purified water; characterized in that the coagulants added in step a) comprise at least one modified or unmodified tannin and a starchy liquid composition containing a solubilized cationic starch, said liquid starchy composition having a viscosity, measured according to an A test, greater than 1000 mPa .s, this test A consisting of adjusting the dry mass cationic starch of the 10% liquid composition and then measuring the Brookfield viscosity at 25 ° C of the resulting composition. The invention also relates to a liquid composition of cationic starch and tannin suitable for use in the process. |
