Abstract
Due to its unquestionable properties and besides its natural abundance, apatitic calcium phosphate is used, in the present work, to discolor the textile waste effluents using the method of coagulation-flocculation. The characterization of effluents, before and after treatment, was realized by the UV Spectrophotometer and the dosage of the chemical oxygen demand (COD). Results show that the color of textile waste effluents before and after coagulation flocculation has shown that after an operation of liming, the color reduction was 70 % and the organic load reduction was of 75 % using a dose of 4 g.L-1 of apatite during 90 minutes as maximal time of treatment in optimal operating conditions (pH, current density, reaction time, etc). The reproducibility of the results proves the satisfactory and encouraging properties of apatitic calcium phosphate as coagulant for the discoloration of the studied textile waste effluents.
