“…Sulfide generation by sulfate reducing bacteria (SRB) and Pi mobilization linked with Fe oxidation/reduction processes can be modulated for controlled metals immobilization. For example, biological oxidation of Fe(II) to Fe (III) can promote the recovery of Fe but also control the Fe concentration in bioleaching (Nurmi et al, 2009). Sulfate reduction and generation of sulfide can be used to selectively precipitate bivalent metals (Chen et al, 2009; Sánchez-Andrea et al, 2014).…”

Limits in resource availability are driving a change in current societal production systems, changing the focus from residues treatment, such as wastewater treatment, toward resource recovery. Biotechnological processes offer an economic and versatile way to concentrate and transform resources from waste/wastewater into valuable products, which is a prerequisite for the technological development of a cradle-to-cradle bio-based economy. This review identifies emerging technologies that enable resource recovery across the wastewater treatment cycle. As such, bioenergy in the form of biohydrogen (by photo and dark fermentation processes) and biogas (during anaerobic digestion processes) have been classic targets, whereby, direct transformation of lipidic biomass into biodiesel also gained attention. This concept is similar to previous biofuel concepts, but more sustainable, as third generation biofuels and other resources can be produced from waste biomass. The production of high value biopolymers (e.g., for bioplastics manufacturing) from organic acids, hydrogen, and methane is another option for carbon recovery. The recovery of carbon and nutrients can be achieved by organic fertilizer production, or single cell protein generation (depending on the source) which may be utilized as feed, feed additives, next generation fertilizers, or even as probiotics. Additionlly, chemical oxidation-reduction and bioelectrochemical systems can recover inorganics or synthesize organic products beyond the natural microbial metabolism. Anticipating the next generation of wastewater treatment plants driven by biological recovery technologies, this review is focused on the generation and re-synthesis of energetic resources and key resources to be recycled as raw materials in a cradle-to-cradle economy concept.

“…Some immobilization studies described jarosite as an undesirable product because its precipitation within the carrier matrix may cause clogging and Hydrometallurgy 125-126 (2012) 152-156 mass transfer barriers. However, such problems can be avoided by using fluidized-bed reactors (Nemati et al, 1998;Nurmi et al, 2009Nurmi et al, , 2010.…”

“…This method has some advantages like simplicity, low-cost operation, and protection of equilibrium between sulfuric acid and alkali ions (Gan et al, 2017). Several studies are performed on the removal of different ions in solutions by using chemical precipitation (Pogliani and Donati, 2000;Wang et al, 2006;Gramp et al, 2008;Gaikwad and Gupta, 2008;Nurmi et al, 2009;Albrecht et al, 2011;Lin et al, 2016;Gan et al, 2017;Izadi et al, 2017;Alguacil, 2019) However the lower-cost biological techniques are limited.…”

Biorremoción de iones de hierro de la solución de refinado de cobre utilizando “semilla” de jarosita biosintética promovida por Acidithiobacillus ferrooxidans

La disminución de la concentración de iones de hierro de una solución de refinado procedente de la extracción con solvente de cobre es importante para mantener una buena eficiencia de corriente en el proceso de electrolisis. En este estudio, se investigaron los efectos combinados de la “semilla” de jarosita biosintética y Acidithiobacillus ferrooxidans sobre la eliminación de hierro de la solución de refinado de cobre y el efecto del pH. La biosíntesis de “semillas” de jarosita de amonio se realizó de manera eficiente a pH 2 y una concentración de Fe2 + de 50 g·l-1. El porcentaje de eliminación de hierro de la solución de refinado a un pH de 1,5; 2,5 y 5% de dosis de semillas fue de 0,81%, 47,38% y 71,26%, respectivamente. La concentración de hierro en la solución de refinado disminuyó notablemente hasta alcanzar un valor del 71,17% con la incorporación de un 10% en peso de “semilla” de jarosita junto con un 10% V/V de A. ferrooxidans. Esto se debió al aumento en la superficie específica de los sólidos en la solución y a las características magnéticas de A. ferrooxidans que promueven la eliminación de hierro. Se seleccionó un pH 2 y una carga de “semillas” de jarosita del 10% como las condiciones óptimas para la eliminación del hierro de la solución de refinado. Se concluyó que se podría incrementar la recuperación de cobre del refinado biológicamente refinado.
