“…Cuando se usa agua regenerada y se maneja cuidadosamente sus propiedades se obtienen cantidades sustanciales de nutrientes lo que reduce los costos y optimiza el rendimiento de los cultivos (Carr et al, 2011). La composición del suelo mejora la conductividad eléctrica y aporta nutrientes gracias al agua recuperada, aumento de nitrógeno, fósforo y minerales como el amonio y sodio (Fito & Van Hulle, 2020;Mora et al, 2017).…”

El agua es un elemento insustituible que requiere de procesos y medidas sanitarias. La creciente demanda ha promovido de diseños para recuperarla y reutilizarla, uno de los sistemas de innovación es la biorremediación que permite la aplicación de agentes microbianos capaces de degradar los contaminantes. Esta investigación está constituida por la revisión de literatura de fuente primaria para obtener criterios en la aplicación de bacterias para el tratamiento de aguas residuales y la reutilización. La Biorremediación ha demostrado ser una de las alternativas más eficientes y rentables para la eliminación de cuerpos que contaminan el ecosistema, en comparación con los sistemas convencionales físicos -químicas. Sin embargo, los resultados de esta estrategia remediadora dependerán del lugar y condiciones ambientales, es por esta razón la importancia del hallazgo de nuevas biotecnologías e implementación de técnicas rentables aplicadas al bienestar del ambiente y seguridad de la sociedad. Para estudios futuros relacionados a la aplicación de algún tipo de biorremediación se debe realizar un análisis previo de la factibilidad ecológica y económica según las condiciones del ecosistema dañado.

“…Caused by the integrated effect of chemical precipitation and bioaccumulation, dissolved metal cations are extracted from the waste and form separable metal‐concentrated slugs. For full‐scale metal recovery applications, the MBR plant should have Anaerobic and aerobic reactor units with necessary facility installations (Fito & Van Hulle, 2021). Metal precipitating agents, microbes, nutrients, and other possible amendments are also added to the reactor with appropriate regulation.…”

Heavy metals are extensively utilized in modern industries in various process. Subsequently a large quantity of waste generated as byproduct that have great impact on environment. A higher concentration of almost all heavy metals are toxic in nature for all living organisms. Therefore, the wastes discharged from the conventional treatment plants deteriorate the natural ecosystems; qualities of water sources and farmlands. Globally, activated sludge waste treatment technology have been widely used as a metal recovery process. The technique miscarried to attain the anticipated removal efficiency. Recently, membrane biological reactor (MBR) system has emerged as an important alternative to conventional activated sludge (CAS) systems. The work describes the potency of microbes for extraction heavy metal from wastes, the enhancements in biotechnology, characterization of specific wastes, optimization parameters to operate under various conditions that prevail in membrane bioreactors. The performance of the MBR technology shows good results to reduce all types heavy metals with supporting evidence, which obtained from the results of prominent studies.

“…Most of the water uses imply the generation of resultant wastewater. Although a significant part of the generated wastewater is not yet subject to any kind of treatment [8], the production of reclaimed water by appropriate technologies can be a relevant contribution to water resources protection and valorisation [9][10][11]. Reclaimed water consists of wastewater treated by adequate processes that ensure water quality and absence of risk, qualifying the water to be used for some purpose, replacing or decreasing the consumption of freshwater [12,13].…”

Freshwater scarcity is a growing threat to sustainable development, which can be mitigated by adequate management of water resources. Agriculture and related activities consist in the main use of freshwater, but several other human activities present relevant contributions. Because most of the water uses imply the generation of resultant wastewater, the production and use of reclaimed water by appropriate technologies can be part of the solution to that issue. Considering that the use of constructed wetlands (CWs) can be a relevant contribution to the production of reclaimed water, as an eco-friendly alternative to costly advanced water treatment technologies, this work is a review of the last decade of literature on the use of CWs to produce reclaimed water. The results point to a usual focus on the production of reclaimed water for agriculture or urban spaces irrigation. In order to potentiate a broader application of CWs, some directions of future research and use of this green technology are proposed.
