title: Treatment of textile wastewater using a natural flocculant.
abstract: The physicochemical treatment of wastewater is of substantial interest, especially when conventional treatments by biological processes are not amenable. Among the current chemical processes used for industrial wastewater treatment, coagulation-flocculation has received a large attention for high pollutant removal efficiency. This paper summarizes the results of a textile wastewater treatment process aimed at the destruction of colour by coagulation-flocculation process and using an organic natural flocculant: tannic substances. Jar-test experiments were carried out in order to determine the optimum conditions for the removal of organic matter and color. Treatment with studied flocculent (Polysep3000) proved to be effective in a wide pH range (pH < or = 10), very effective in removing the color (96 %) and a fraction of the COD (40-50 %) from the textile wastewater. Polysep3000 is compared to Al2 (SO4)3 and FeCl3 for sludge production. Polysep3000 seems to be suitable for yielding a high removal of color (> 90%) and corresponding low volume of settled sludge.
