“…The experimental results are similar to those obtained by Baena et al (2020) showing higher fluxes for higher concentrations (Baena-Moreno et al, 2020). Furthermore, the water fluxes obtained using NaCl and AMD as extractive solute and FS, respectively, are comparable to some of the results shown by Cabrera-Castillo et al (2021) and Vital et al (2018) (Cabrera-Castillo et al, 2021Vital et al, 2018), initially close to 10 L•m − 2 •h − 1 with 0.5M and around 25 L•m − 2 •h − 1 for the highest concentrations tested. Using the lowest concentration, 0.5M NaCl, it could be possible to recover nearly 50% of the initial water.…”

“…One year later, Pramanik et al (2019) published the recovery of rare earth elements from AMD using 279 g/L NaCl as a draw solution with average fluxes between 9 and L•m − 2 •h − 1 (Pramanik et al, 2019) and Choi et al (2019) used aqueous solutions of tetrasodium ethylenediaminetetraaceticacid and poly sodium-4-styrenesulfonate and achieved average fluxes of 8 L•m − 2 •h − (Choi et al, 2019). The most recent study was developed by Cabrera-Castillo et al (2021) where AMD was treated using a 1M NaCl solution for continuous assays at 60 • C until 50% water recovery was achieved, obtaining a water flux = 25 L•m − 2 •h − 1 (Cabrera-Castillo et al, 2021). In these studies, the draw solutions used had reduced osmotic pressure, which limits the feed concentration and water recovery (NaCl 0.5M and 1M), or were high-priced solutes (tetrasodium ethylenediaminetetraaceticacid and poly sodioum-4-styrenesulfonate), or their regeneration involved high energy consumption (NH4HCO3).…”

“…But although the fouling propensity in the FO process is lower than in other membrane technologies such as reverse osmosis, the feasibility of the FO is affected by the possible layer of precipitates (e.g. gypsum) on the membrane in terms of water flux decline (Cabrera-Castillo et al, 2021;Xie et al, 2016). For this reason, in order to obtain high levels of metals and water recovery in a combined process, it is ideal to combine both types of technology by alternating concentration steps (water recovery) with the precipitation steps, where possible solids are eliminated.…”

Water scarcity poses a significant threat to global food and water security, prompting a need for practical solutions. With 97% of Earth’s water situated in oceans, desalination emerges as a viable option. Among desalination technologies, forward osmosis (FO) using membrane-based technology stands out for its potential to reduce costs and energy requirements. The focus on energy consumption in FO has prompted an exploration of optimal technology selection through the Analytical Hierarchy Process (AHP), a multi-criteria decision-making method. Value judgments were collected through a questionnaire in consultation with two experts. Environmental aspects emerged as the most critical factor, weighted at 0.3963. The AHP analysis revealed nanofiltration (NF) as the optimal system, attaining a total weight of 0.2612. The NF scored highest in terms of environmental impact (C3), operating and maintenance costs (S6), and energy requirements (S4). Conversely, membrane distillation ranked as the least preferred alternative, with a total score of 0.1335, mainly due to lower maturity of technology (S3), higher capital costs (S5), and negative environmental impact (C3). Sensitivity analysis was conducted to investigate how changing weights for sub-criteria might affect the preferred technology. Notably, Reverse Osmosis became the most favored technology when efficiency (S1) and S3 weights were set at 0.3 and 0.2, respectively. Conversely, thermal separation gained preference when the weights for resistance to scaling and fouling (S2) and S5 were set at 0.3. Changes in S4, S6, and C3 have showed the most minor sensitivity.

“…Therefore, a robust and well-structured index, including the summary of each hybrid process figure called the Ranking Efficiency Index (REI), was introduced to evaluate the trade-off between the merits and demerits of represented MHSs. To this end, four different pilot/full-scale MHSs, including FO-NF [319], FO-RO [319], UF-RO [320], and FO-MD [321], have been considered in this review to reach an overall qualitative comparison in the field of water recovery from different types of wastewater streams.…”

(English) Changing wastewater treatment plants into wastewater and resource recovery facilities represents a paradigm shift in wastewater management. Resources such as water, energy, and nutrients are becoming scarcer, which makes this shift necessary. Wastewater is often treated as a waste product in traditional wastewater treatment plants, wasting valuable resources. We can extract and reuse these resources when we shift to resource recovery facilities, making our approach more sustainable and efficient. Alternatively, by transitioning to wastewater and resource recovery facilities, serious disadvantages such as high energy consumption, limited resource recovery, high operating costs, and non-treatment of wastewater can be addressed by promoting resource efficiency, reducing environmental impact, promoting the circular economy, and sustainable today's wastewater management process. Domestic/Urban wastewater discharges contain various substances, including organic matter, nutrients like nitrogen and phosphorus, and trace elements. The next generation of wastewater treatment facilities will transform into ecologically friendly facilities, including resource recovery facilities. By strongly emphasizing the reclamation and reuse of these substances rather than treating them as contaminants, they will play a significant role in Smart Cities. This strategy closes the loop by promoting the circular economy and ensuring that the substances are fully utilized. By integrating membrane technologies with superior features, wastewater treatment plants can enhance nitrogen recovery efficiency and provide drinking water. This work examines and validates a hybrid technology that uses Ion Exchange-Natural Zeolite and Hollow Fiber Liquid-Liquid Membrane Contactors as an innovative and well-established treatment system for the removal/recovery of ammonium/ammonia from urban/domestic wastewater streams to reduce water scarcity and nutrient pollution, resulting in N-liquid fertilizers. Using this membrane hybrid system, liquid fertilizers could be produced and concentrated on reaching standard commercial levels in the N market per the European Commission, and also clean water was produced, which met the WHO and EU discharge targets for nitrogen. (Español) Cambiar las plantas de tratamiento de aguas residuales por instalaciones de recuperación de aguas residuales y recursos representa un cambio de paradigma en la gestión de aguas residuales. Recursos como el agua, la energía y los nutrientes son cada vez más escasos, lo que hace necesario este cambio. Las aguas residuales a menudo se tratan como un producto de desecho en las plantas de tratamiento de aguas residuales tradicionales, desperdiciando recursos valiosos. Podemos extraer y reutilizar estos recursos cuando cambiamos a instalaciones de recuperación de recursos, lo que hace que nuestro enfoque sea más sostenible y eficiente. Alternativamente, mediante la transición a instalaciones de recuperación de recursos y aguas residuales, las desventajas graves como el alto consumo de energía, la recuperación limitada de recursos, los altos costos operativos y la falta de tratamiento de las aguas residuales pueden abordarse mediante la promoción de la eficiencia de los recursos, la reducción del impacto ambiental, la promoción de la economía circular, y sustentable el proceso actual de manejo de aguas residuales. Los vertidos de aguas residuales domésticas/urbanas contienen diversas sustancias, entre las que se incluyen materia orgánica, nutrientes como nitrógeno y fósforo, y oligoelementos. La próxima generación de instalaciones de tratamiento de aguas residuales se transformará en instalaciones ecológicas, incluidas las instalaciones de recuperación de recursos. Al enfatizar fuertemente la recuperación y reutilización de estas sustancias en lugar de tratarlas como contaminantes, desempeñarán un papel importante en las Ciudades Inteligentes. Esta estrategia cierra el círculo al promover la economía circular y garantizar que las sustancias se utilicen por completo. Al integrar tecnologías de membrana con características superiores, las plantas de tratamiento de aguas residuales pueden mejorar la eficiencia de recuperación de nitrógeno y proporcionar agua potable. Este trabajo examina y valida una tecnología híbrida que utiliza contactores de membrana líquido-líquido de fibra hueca y zeolita natural de intercambio iónico como un sistema de tratamiento innovador y bien establecido para la eliminación/recuperación de amonio/amoníaco de corrientes de aguas residuales urbanas/domésticas para reducir el consumo de agua. escasez y contaminación de nutrientes, lo que resulta en fertilizantes N-líquidos. Con este sistema híbrido de membrana, se pudieron producir y concentrar fertilizantes líquidos para alcanzar los niveles comerciales estándar en el mercado de N según la Comisión Europea, y también se produjo agua limpia, que cumplió con los objetivos de descarga de nitrógeno de la OMS y la UE.
