Water is an important and vital element for life, which is why there is increasing emphasis on caring for it and managing improvements to preserve its quality, especially in the water sources used to obtain water for human consumption. 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.
