Reduction of the Biochemical Oxygen Demand of the water samples from the lower basin of the Chillon River by means of Air-Ozone MicroNanobubbles, Ventanilla - Callao

Abstract

The dumping of domestic and industrial wastewater is one of the major problems facing rivers, the high level of pollution directly affects aquatic and plant life. Producers living near to the Chillon River use these waters to irrigate their farms, many of the food products are taken to shopping centers in the city and then consumed by the population. Due to this reason, this research aims to reduce or eliminate pollutants by measuring the Biochemical Oxygen Demand (BOD); since it is considered as a test of great value in the analysis of sewage effluent or highly contaminated. The results show that the mean initial sample was 173 mg/L. after treatment at 15 minutes with air Micro Nanobubbles was obtained 53 mg/L and with ozone Micro Nanobubbles was obtained 53 mg/L. The best obtained efficiency was 69.36%
