TRUJILLO, Daniela et al. Remoción de turbiedad en agua de una fuente natural mediante coagulación/floculación usando almidón de plátano. Rev. ion [online]. 2014, vol.27, n.1, pp.17-34. ISSN 0120-100X.

This work presents the analysis of turbidity removal in water from a natural source, via coagulation/ flocculation using plantain starch. A random factorial experimental design was formulated with four variable factors: pH, coagulant dose, rapid mixing speed and slow mixing speed. The jar test was carried out in order to determine the optimal values of such factors. The plantain starch is proper as flocculation aid, although its sedimentation is slow. The best turbidity removal corresponds to: pH of 5, a 50:50 weigh percent for the alum sulfate/plantain starch combination, fast mixing speed of 150rpm and slow mixing speed of 20rpm.

Keywords : coagulation; advanced primary treatment; polymer; sedimentation.
