Quantitative study of the variable pollutant load in hospital wastewater from the Imbanaco Clinic in the city of Cali

Water contamination by emerging contaminants due to human activities has become one of the most critical difficulties in recent years. Within this problem of wastewater, we find hospital wastewater, catalogued as an important source of environmental risk due to the presence of metabolites and emerging micro contaminants. This wastewater includes laundry, kitchen, cleaning and diagnostic services, as well as care, laboratory, research and diagnostic activities. It is a challenge for health service providers to address this problem and comply with current environmental regulations. There are different processes, including advanced oxidation processes, in this case by ozonation. However, it is important to know the pollutant nature of each effluent that is why the purpose of this research was to identify the organic load contributed by the liquid waste from the headquarters of the Imbanaco Medical Center located in the city of Cali, Valle del Cauca, the experimental design evaluated allows concluding that the cleaning and sterilization supplies used in the Imbanaco Medical Center are highly recalcitrant and exceed the maximum permissible limits established by resolution 0631 of 2015.
