Abstract
El agua, es un elemento importante y vital para la vida, por ello cada vez es mayor el énfasis en cuidarla y gestionar mejoras para conservar su calidad, sobre todo en las fuentes de agua usadas para obtener el agua de consumo humano. La contaminación del agua puede ser fisicoquímica y microbiológica. Este trabajo de investigación tuvo como objetivo determinar el efecto biocida del sulfato de cobre pentahidratado(CuSO4.5H2O)sobre los organismos de vida libre (OVL):algas, protozoarios, copépodos, rotíferos, y nemátodos en todos sus estados evolutivos ,debido a su difícil eliminación en los procesos de desinfección convencionales de las plantas de tratamiento de agua potable(PTAP)por su alta resistencia a la cloración; para ello se realizaron ensayos en agua natural tomada de la cámara de reunión PTAP-SEDACAJ, El Milagro, que es abastecida por dos principales ríos: Porcon y Grande, cada unidad muestral fueron sometidas a diferentes concentraciones y tiempos de exposición al CuSO4.5H2O usando el equipo de jarras , la evaluación cuantitativa requirió dejar sedimentar a estas muestras por espacio de 7 días, luego se las concentra con la ayuda de una manguera y bombilla de succión ; se eliminó el 90 % de sobrenadante, hasta obtener un volumen residual aproximado al10%;usando una micropipeta se tomó 1ml para verterla en la cámara de Sedgewick -Rafter (S-R) para su conteo al microscopio. Se obtuvieron los resultados después de registrar el conteo y aplicar la fórmula para el cálculo de estos organismos concluyendo, que el tratamiento T16 con la concentración 70mg/L de CuSO4.5H2O y expuesta al tiempo de 60 minutos, es la que tuvo el mayor efecto biocida con un porcentaje de 68% en reducción poblacional de los OVL.

Water contamination can be physicochemical and microbiological. This research work aimed to determine the biocidal effect of copper sulfate pentahydrate (CuSO4.5H2O) on free-living organisms (OVL): algae, protozoans, copepods, rotifers, and nematodes in all their evolutionary states, due to its difficult to eliminate in conventional disinfection processes of drinking water treatment plants (PTAP) due to its high resistance to chlorination; For this, tests were carried out in natural water taken from the PTAP- SEDACAJ meeting chamber, El Milagro, which is supplied by two main rivers: Porcon and Grande, each sample unit was subjected to different concentrations and exposure times to CuSO4.5H2O using The jar team, the quantitative evaluation required letting these samples settle for 7 days, then concentrating them with the help of a hose and suction bulb; 90% of the supernatant was removed, until a residual volume of approximately 10% was obtained; using a micropipette, 1 ml was taken to pour it into the Sedgewick-Rafter (S-R) chamber for counting under the microscope. The results were obtained after recording the count and applying the formula for the calculation of these organisms, concluding that the T16 treatment with the concentration of 70 mg/L of CuSO4.5H2O and exposed to the time of 60 minutes, is the one that had the greatest effect. biocide with a percentage of 68% in population reduction of OVL.
