Potato Starsch (Solanum Tuberosum) And Its Effect On Water Turbidity For Population Consumption Almidón De Papa (Solanum Tuberosum) Y Su Efecto En La Turbidez Del Agua Para Consumo Poblacional

Abstract

The objective of this research was to evaluate the coagulating power of potato starch (Solanum tuberosum) cultivar Unica, and aluminum polychloride for the removal of turbidity from water entering the Samegua treatment plant, Moquegua/Peru. The completely randomized design (CRD) was applied, under a factorial arrangement of A and B where nine mixtures were made. The sampling point chosen was the intake of water from the Ollería catchment to the Samegua water treatment plant. The natural potato starch coagulant was obtained using crushing, filtering, sedimentation, drying and sieving operations, with a yield of 17.5% starch. The analysis of the results obtained allowed establishing that the optimum concentration of potato starch was 133.0 mg/l (0.2 g of starch), achieving the removal of the turbidity parameter at 6.3 NTU, and the most suitable concentration of aluminum polychloride was 2072.0 ml/l (13.0 ml of aluminum polychloride), achieving the removal of the turbidity parameter at 9.1 NTU. The results of the optimum mixtures correspond to treatment 5 with 133.0 mg/l of potato starch (0.2 g) as a coadjuvant agent mixed with 1597.0 ml/l of aluminum polychloride (10.0 ml), achieving a turbidity of 7.8 NTU. In conclusion, it was found that the coagulating power of potato starch, cultivar Unica, gave better results than aluminum polychloride for the removal of turbidity at the entrance of the water to the Samegua treatment plant.
