“…The other main problem in our study sites is coliform contamination; to face this issue, it is necessary to implement alternatives for biological treatment that show the best economic, functional, and operational profitability. The most widely used in Colombian territory are usually stabilization lagoons, wetlands, and activated sludge, which when used together reflect optimal results greater than 90% in the treatment of domestic wastewater, in case of water shortage (a common situation in rural regions) an alternative water resource may be to reuse the latter [45][46]. Quality control through physicochemical and microbiological analyzes is essential; however, it is not enough to guarantee the final quality of drinking water; it is just as important to have comprehensive management in drinking water distribution systems (WDS) [47][48][49].…”

This study evaluates the water quality for human consumption in the municipalities of Sincerín and Gambote. It was measured through physico-chemical (color, turbidity, conductivity, pH, dissolved oxygen, hardness, and heavy metals) and microbiological (total coliforms, Escherichia coli) parameters before and after a partial form of water treatment was used (alum and chlorine addition in Gambote and Sincerín municipalities, respectively). This investigation was done in accordance with the maximum permissible values established by the Resolution 2115 of 2007 of the Ministry of Environment, Housing, and Territorial Development of Colombia (MAVD in Spanish). Additionally, the IRCA (Water Quality Risk Index) was calculated to determine the degree of risk of disease occurrence. The results indicated concentrations higher than the recommended values for: (a) hardness (in Sincerín); (b) iron (Fe), turbidity (only before being treated), E. coli (in Gambote); and (c) mercury (Hg), and total coliforms. The water supplies of the municipalities presented unsafe IRCA. Therefore, it is expected that the results of this study could be used for proposing strategies for improving these conditions by means of the design and implementation of an adequate treatment system.

“…El proceso de tratamiento de aguas tanto potables como residuales se basa en un tratamiento químico inicial a base de coagulantes y floculantes para remover la mayoría de los contaminantes [1]. Algunos países en vía de desarrollo no cuentan con sistemas eficientes de tratamiento de aguas residuales; ya sea por problemas económicos, o debido al limitado conocimiento sobre alternativas viables de bajo costo, a pesar de ser una herramienta para mejorar la calidad del agua [2]. Además, el uso de estas aguas en los cultivos resulta atractivo para los agricultores, por su accesibilidad y el bajo costo que les representa en el uso de fertilizantes, pero existen múltiples impactos negativos en los ámbitos social, ambiental y económico, desde problemas de salud hasta contaminación de los suelos [3].…”

Wastewater pollution has been causing great concern throughout the world in recent decades since it seriously affects flora and fauna and transmits diseases such as typhoid fever, dysentery, cholera, among others. Therefore, in the present systematic review, natural flocculants and coagulants for the remediation of wastewater in South America were identified and compared, according to research journals published in scientific databases, in the last ten years. Information from scientific articles and academic theses belonging to the SciElo, Redalyc and Google Scholar databases was used considering the period 2012 -2022 and the Spanish, English and Portuguese languages. 60 articles were identified, of which 10 that did not meet the research objective were discarded, reaching a total of 40 articles and 10 selected theses. A greater number of studies from Colombia was found, followed by Peru and Ecuador. One of the main limitations was the lack of command of the Portuguese language, since 4 articles written in that language were identified. Likewise, being South America the study area, limited articles related to flocculation and natural coagulation were found, of which 50 were selected for the present systematic review. As a result, the most effective species for the remediation of wastewater were identified. It is concluded that the most outstanding species Moringa oleifera "Moringa" and Opuntia ficus-indica "Tuna" present an efficacy for the remediation of wastewater inSouth America as flocculants and coagulants obtaining contaminant removal yields of up to 99.29% for turbidity and 99.96% for total coliforms.

“…Luego, el tratamiento secundario incluye tecnologías basadas en procesos bioquímicos, donde las aguas residuales son sometidas a reacciones metabólicas mediadas por microorganismos con la capacidad de reducir la materia orgánica disuelta que se encuentra presente en el caudal vertido, bajo una serie de condiciones controladas, de lo que se obtienen remociones de hasta el 80 % de DBO (Superintendencia de Servicios Públicos Domiciliarios, 2013, Torres, 2012, Vargas et al, 2020. No obstante, para el año 2010, tan solo el 45 % de los STAR contaba con algún tipo de tratamiento secundario cuya implementación incluía diferentes procesos bioquímicos aerobios o anaerobios, para la remoción biológica de contaminantes presentes, como lagunas [113] abiertas, sistemas de lodos activados acoplados a sedimentadores secundarios, filtros percoladores o reactores de flujo ascendente (UASB por su sigla en inglés) (Ministerio de Ambiente Vivienda y Desarrollo Territorial, 2010, Vargas et al, 2020).…”

Contexto: En Colombia, la baja cobertura de plantas de tratamiento de aguas residuales conlleva a una compleja problemática ambiental, ya que estas aguas son usadas generalmente como sistemas de riego para cultivos y, en ocasiones, para el consumo humano en zonas rurales. Objetivo: Informar acerca del saneamiento básico de las aguas residuales, los sistemas de tratamiento, el uso de microorganismos exoelectrogénicos en biorreactores, así como, los avances reportados frente al uso de los sistemas bioelectroquímicos y su posible implementación en Colombia. Metodología: Se describe la capacidad y cobertura de los sistemas de tratamiento en las regiones del país; posteriormente, se presenta el fundamento teórico de los microorganismos que interactúan en los sistemas bioelectroquímicos; y se documenta el uso de esta tecnología para depurar contaminantes. Resultados: El uso de bacterias exoelectroquímicas puede degradar carga orgánica contenida en las aguas residuales; los sistemas bioelectroquímicos aprovechan la capacidad de los microorganismos para transferir electrones a través de un circuito eléctrico por medio de voltaje, y obtener energía en forma de corriente eléctrica o combustibles con alto poder calorífico. Conclusiones: La implementación de estos sistemas en Colombia requiere de inversión tecnológica, humana y de infraestructura en las principales plantas de tratamiento de aguas residuales, dada la complejidad y variabilidad de los fenómenos bioelectroquímicos asociados a la conversión de materia orgánica.
