    In this research the sludge’s from purification plant Casigana from Empresa Pública Empresa Municipal de Agua Potable y Alcantarillado de Ambato (EP-EMAPA-A) product of its processes was used for obtaining aluminum sulphate as coagulant. The acidification method with sulfuric acid extracted aluminum sulphate type b with physicochemical characteristics suitable for its clarification of water (color removal and turbidity). The aluminum sulphate was obtained by a reaction of the sulfuric acid with aluminum hydroxide (compound present in the sludge) in which the following factors were evaluated; pH of the reaction is carried and the reaction time under agitation, the experimental response was the concentration of aluminum in mg * L-1 obtained in the supernatant. These factors were analyzed by an experimental design of blocks totally random. Resulting in a pH of 1.5 for 30 minutes of reaction; Allowed a recovery of 72.2% of aluminum as aluminum sulfate type b, ensuring its effectiveness as a coagulant according to standards NTE 1903 and NTC: 531 para productos químicos. Sulfato de Aluminio national norm and Colombian norm referenced in Ecuador. The efficacy and dose of the coagulant was evaluated in a jar tests, collecting water samples from the effluent treated by the Casigana treatment plant, evaluating the color and residual turbidity to comply with the NTE 108: 2011 standard.
