Pollutant removal assessment involves determining the effectiveness of processes or technologies in removing unwanted substances from a medium, such as water, soil or air. It is assessed by measuring the concentration of pollutants before and after treatment, calculating the removal efficiency.
Evaluation Process:
Identification and Quantification of Contaminants: Contaminants present are identified and their concentration in the medium prior to treatment is determined. This may involve laboratory analysis and the use of techniques such as spectroscopy or biosensors.
Treatment Method Selection: The most appropriate treatment method is chosen for the type of contaminant and the affected media. This may include biological, physical or chemical treatments.
Treatment Application: The selected treatment method is applied to the contaminated media.
Removal Assessment: Re-measure the concentration of contaminants in the media after treatment.
Calculation of Efficiency: The percentage of removal is calculated using the following formula.
The sub-basin of the Nexapa river is located in the region No. 68 of the upper part of the Balsas river basin, it is fed by the thaws of the eastern slope of the Popocatepetl volcano, in its initial portion it receives contributions from the city of Puebla through the Potezuelo channel, this effluence has a high pollutant load because it comes from a highly urbanized area.
This, together with the contributions from the municipalities of Atlixco and Izucar de Matamoros has caused a tendency in the river, various organic pollutants such as stimulants, fragrances and drugs among other personal care products, which although they are in concentrations of the order of parts per trillion (ppt), the fact that they are constantly releasing them makes them pseudopersistent pollutants.
With the aim of evaluating alternative, viable and sustainable techniques for the purification of urban wastewater, this work was carried out by establishing purification systems at the mesocosm level, at the end of the secondary treatment of the wastewater treatment plant in the municipality of Izúcar de Matamoros; a Latin square experimental design was used to evaluate the effect of the variables on the efficiency of regulation of physicochemical parameters.
