EFICIENCIA DEL CARDÓN GUAJIRO Y QUITOSANO EN REMOCIÓN DE PARAMETROS FISICOQUÍMICOS EN AGUAS RESIDUALES DOMESTICAS.

The efficiency of two natural coagulants was evaluated and compared: Cardón Guajiro and Quitosano to treat the wastewater of the Sonesta Valledupar hotel. The Cardón Guajiro was extracted by a process of drying, grinding, sieving and extraction with anhydrous methanol. Chitosan in the form of scales. Jar tests were carried out to determine ranges, optimal doses and analyze the study parameters as these coagulants were applied. Two tests were carried out with concentrations of 5% and 10% for Cardón Guajiro and two for Chitosan at a concentration) of 1%. The doses of Cardón between 10 and 100 PPM in intervals of 10, the doses of Chitosan from 50 to 500 PPM in intervals of 50. The Cardón at a concentration of 5% generated excellent results in the study parameters. Chitosan showed better removal percentages than Cardón guajiro. [ABSTRACT FROM AUTHOR]
