There are notable environmental problems related to the use and management of water, which is why industries seek clean technologies with greater efficiency in decontamination and with a minimum investment such as the application of nanobubbles in the treatment of wastewater. Therefore, the objective of this research isbased mainly on the application of air-oxygen nanobubbles in the laboratory, determining the efficiency in the removal of contaminants in the treatment of Covicorti wastewater in the City of Trujillo and to make a comparasion with the maximum permissible limits, form Peruvian Normative about water used as a recreational zone or irrigation.The experimentation of the research work was carried out with a sample of the effluent of the Aereated-facultative Lagoon from Covicorti, these waters were treated in the laboratory, in a nanobubble generating system composed of a 0.5 HP pump, air generator and medicinal oxygen connection at 0.5 psi. The effect of the air-oxygen nanobubble about the OD,DQO,DBO5, thermotolerant coliforms and heavy metal (Pb,Cd,Fe,Cu,Zn,Cr,Mn,Ba,Al,Hg) concentrations was analized. The results showed that the treatment with air-oxygen nanobubbles managed to improve the quality of the water at 20 minutes, reducing the concentration of OD in 66.68%, of COD in 64.76%, DBO5 in 66.66% and metals heavy at 28.50%
