description | En la clarificación del agua potable se utiliza sulfato de aluminio para remover materia coloidal y sustancias orgánicas, mejorando la calidad del agua. Elevadas concentraciones de aluminio residual en el agua potable tienen implicaciones en la salud humana, siendo necesario el desarrollo de coagulantes alternativos, ambientalmente aceptables para reemplazar los productos químicos. En esta investigación se estudió el exudado gomoso de Samanea saman como coagulante natural, estableciendo su dosis óptima mediante la prueba de jarro y determinando los parámetros: turbidez, color, pH, alcalinidad total, número más probable y conteo de heterótrofos, usando agua turbia sintética inoculada con un cultivo puro de Escherichia coli y solución de coagulante en dosis de 10-500 mg/L, con valores de turbidez inicial entre 10-100 NTU. La dosis óptima del coagulante resultó entre 10-25 mg/L, obteniendo disminuciones significativas en los valores de turbidez (1NTU) y color (5 UC), los valores de pH y alcalinidad total no presentaron variaciones significativas, los coliformes fecales y totales tuvieron remociones significativas (99,7% y 99,8% respectivamente) y el conteo de heterótrofos de observó con 0 UFC. Los parámetros evaluados cumplen con los estándares establecidos para garantizar la calidad del agua para consumo humano, usando el exudado gomoso de Samanea saman, demostrando la eficiencia de este coagulante natural.<br>For the clarification of drinking water aluminium sulphate is used to remove colloids and organic substances to improve the water quality. High concentrations of residual aluminium in the drinkable water can have implications on human health, thus, it is necessary to develop alternative environmentally acceptable coagulants. The exudates gums from Samanea saman were studied as natural coagulants, establishing optimum dose according to the jar test and determining parameters such as: turbidity, colour, pH, total, alkalinity, MPN and heterotrophic count; using synthetic turbid water inoculated with pure culture of E. Coli and coagulant solution on the volume range of 50 to 500 mg/L. The initial turbidity used was between 10 to 100 NTU. The optimum coagulant dose was found to be between 10 to 25 mg/L, with significant reduction of turbidity and colour, i, e,: 1 NTU for turbidity and 5 U for colour. The pH and total alkalinity did not present significant variations. On the other hand, for fecal coliforms a significant removal of 99.7%, and for total coliforms (99.8%) was found. And finally, the heterotrophic count was observed with 0 UFC. The parameters evaluated using the exudates gum from Samanea saman, comply with the standard established to guarantee the quality of water for human consumption, showing the efficiency of this natural coagulant. |
