HUMANANTE CABRERA, Juan José et al. Removal Efficiency and impact of wastewater treatment system in the urban and rural sector of the Santa Elena Province. Manglar [online]. 2022, vol.19, n.2, pp.177-187.  Epub June 15, 2022. ISSN 1816-7667.  http://dx.doi.org/10.17268/manglar.2022.022.

A wastewater treatment system consists of a series of physical, chemical, and biological processes that aim to eliminate the contaminants present in the water. The objective of the research is to evaluate the wastewater treatment systems of the Punta Carnero sector, Ancón and Anconcito parish, through an experimental descriptive investigation to know the impact generated by the contamination parameters due to the incorrect treatment of these with respect to the analysis. of its efficiency and final discharge from the urban-rural area of the Province of Santa Elena. The removal efficiency of pollutant loads was evaluated in percentage and the final discharge by the mean and standard deviation from 2015 to 2020. It was determined that the Ancón and Anconcito systems have better removal efficiency than Punta Carnero., however, the percentage is not optimal. The discharge of fecal coliforms, chemical oxygen demand, total suspended solids, and surfactants in none of the systems complies with the maximum permissible limits of Ecuadorian regulations. It was known that these systems generate negative impacts on health and the environment of the sector under study.
