This paper presents a comprehensive review of studies on electrodialysis (ED) applications in wastewater treatment, outlining the current status and the future prospect. ED is a membrane process of separation under the action of an electric field, where ions are selectively transported across ion-exchange membranes. ED of both conventional or unconventional fashion has been tested to treat several waste or spent aqueous solutions, including effluents from various industrial processes, municipal wastewater or salt water treatment plants, and animal farms. Properties such as selectivity, high separation efficiency, and chemical-free treatment make ED methods adequate for desalination and other treatments with significant environmental benefits. ED technologies can be used in operations of concentration, dilution, desalination, regeneration, and valorisation to reclaim wastewater and recover water and/or other products, e.g., heavy metal ions, salts, acids/bases, nutrients, and organics, or electrical energy. Intense research activity has been directed towards developing enhanced or novel systems, showing that zero or minimal liquid discharge approaches can be techno-economically affordable and competitive. Despite few real plants having been installed, recent developments are opening new routes for the large-scale use of ED techniques in a plethora of treatment processes for wastewater.

“…Under anoxic conditions, the PMDC system produced a maximum power density of 84 mW m −3 with the removal of 40% of salt from saline wastewater (Kokabian and Gude, 2013). Furthermore, Wang et al also developed a 1 L up-flow-stacked MDC (USMDC) for the removal of salts from synthetic wastewater with the simultaneous production of bioelectricity (Wang et al, 2020). After 120 days of continuous operation, 32.91 W m −3 of power density was obtained from the USMDC with a salt removal efficiency of 91.9%, which was 1.5 times more than single-up-flow MDC (Wang et al, 2020).…”

A Sustainable Approach for the Production of Green Energy With the Holistic Treatment of Wastewater Through Microbial Electrochemical Technologies: A Review

2021

View full text Add to dashboard Cite

With the plausible depletion of fossil fuels in the near future and its associated environmental impacts, researchers have instigated the search for eco-friendly renewable bioenergy. Moreover, the increase in water pollution by industrial and anthropogenic activities is another alarming global concern. In this regard, the production of renewable and sustainable green bioenergy utilizing wastewater through microbial electrochemical technologies (METs) can alleviate these crucial problems by providing a sustainable solution to meet both the demands of energy and fresh water supply. Moreover, different bio-centered techniques such as nitrification and denitrification for nitrogen removal, and elimination of carcinogenic metals, pathogens, and organic components utilizing microbiota followed by toxicity sensing of different pollutants have been efficaciously exhibited through METs. However, inferior bioenergy production and recovery of low biomass yield in METs with high operational cost are noteworthy bottlenecks that hinder the scalability of this technology. Therefore, this review elaborates different physicochemical factors affecting the performance of METs, microbial interaction for the development of stable biofilm and so forth. Moreover, a broad overview on the production of bioenergy, along with the removal of pollutants from wastewater through different types of METs are also highlighted. Furthermore, the production of biofuels like ethanol, methanol, biodiesel, and gaseous fuel like bio-H2 coupled with power generation using photosynthetic microorganisms via CO2 sequestration through METs are also discussed. Additionally, recent developments with future scope for the field-scale implementation of METs along with their bottlenecks have been discussed, which has not been critically reviewed to date.

“…10 A basic three-chamber MDC contains a middle desalination chamber, which is separated from the anode chamber by an anion exchange membrane (AEM) and a cathode chamber by a cation exchange membrane (CEM). MDC has achieved great development in reactor configuration and processing scale, 11 which further improves the desalination efficiency and power generation of MDC. However, the lack of studies on the impact mechanisms of ion behaviors on the…”

Microbial desalination cells (MDCs) provide a sustainable approach to desalinate saltwater powered by bacterial metabolism during organic oxidation. A systematic study was conducted to clarify the ion-dominated interactions for preventing unpredictable risks for long-term MDC operations in the treatment of complex ion-containing wastewaters. The investigation showed that the migration and unequal scaling of cations at different ion exchange membrane (IEM) surfaces greatly influenced their transmembrane processes, which were directly affected by the hydrolysis and precipitation behavior controlled by the solubility product and ambient solution, resulting in the following removal efficiency of MDCs: Na + >Ca 2+ >Cu 2+ >Al 3+ >Fe 3+ . A further study showed that the precipitation antagonism and pH buffer effect of multiple cations could positively promote the desalination of sparingly soluble cations. Eventually, the desalination efficiency of MDC in the treatment of actual industrial tailwater was maintained at 63.2-74.1%. These findings not only elucidated the kinetics of ion migration in detail but also offered new application possibilities for MDCs.
