“…TC remaining in water has the potential to pose safety risks due to the generation of undesirable by-products and its high reactivity. Trihalomethanes (THMs), a representative by-product formed during the disinfection process, are of particular concern due to their potential carcinogenicity, which poses a severe health risk (Andersson et al, 2019;Dock et al, 2019). Additionally, the adverse effects of free chlorine that remains in disinfected seawater result from its reaction with organic compounds in seawater, which can have wide-ranging impacts on aquatic life and the ecosystem (Pan et al, 2019).…”

Seawater represents an inexhaustible reservoir of valuable resources, containing vast quantities of both water and minerals. However, the presence of various impurities in seawater hinders its direct utilization for resource extraction. To address this challenge, an electrochemical method employing a solid electrolyte known as NASICON (Sodium Super Ionic Conductor) offers effective solutions for extracting valuable resources from seawater. The NASICON ceramic acts as a robust barrier against impurities and facilitates the selective transport of Na+. This review provides a comprehensive examination of NASICON ceramics, offering an overview of the concept and highlighting the competitive advantages of NASICON-based electrochemical systems, particularly in the realms of energy storage, hydrogen production, sodium hydroxide and chlorine synthesis, water treatment, and mineral extraction. Furthermore, this study outlines the key challenges that need to be addressed and discusses the trajectory of its development toward becoming a mature technology.

“…Ballast water is utilized to maintain vessels' hull balance, control the trim, stability and stresses when vessels sail without cargo (Rigby et al, 1999), it is estimated that approximately 10 billion tons of ballast water are transferred globally through oceangoing vessels each year (Romanelli et al, 2019). Ballast water is normally collected from the departure ports or the passing coastal waters (Sáenz Alcántara et al, 2018), and may contain many planktons, pathogens like Vibrio (Altug et al, 2012;Ng et al, 2018), heavy metal (RezaTolian et al,2020), microplastic (Naik et al, 2019) as well as other substances, therefore, discharge of ballast water from ships can evoke multiple ecological risks to the receiving environment (Dock et al, 2019). The International Maritime Organization (IMO) is aiming at eliminating or reducing dangerous invasive organisms or species transmitted through ballast water discharge.…”

In nowadays, world trade and cargo transportation mainly rely on shipping, and inland ports provide valuable and essential services to the maritime transport. With the increase of trade volume, the discharge of ballast water from ships is also increasing, which brings in ecological challenges. The International Maritime Organization stipulates that the number of organisms in discharged ballast water should be limited to prevent biological invasion to recipient waters. However, ballast water still contains many substances of source water, and may affect the plankton community in the recipient waters. In this study, the effects of ballast water on nature freshwater plankton community were evaluated at laboratory scale. It was observed that the abundance and diversity of planktons decreased with increase of water salinity. Through 10 days of continuous monitoring, it was found that ≥ 50 µm organisms were more sensitive to rising salinity than 10–50 um organisms, when water salinity was not over 3.6‰, there was no significant difference on ≥ 50 µm organisms quantity and diversity compared with the freshwater control group after 10 days, and the biota maintained certain recovery ability, while 10–50 um organisms had recovery ability when water salinity was not over 6.5‰. However, when the water salinity was over 6.5‰, both species composition and organism density showed irreversible and rapid reduction. In addition, organism species Platyias sp., Polyarthra sp., Tribonema sp., Navicula sp. were found to be very sensitive to salinity change and could be considered as indicative organisms for monitoring and evaluating ecological effect of discharge of saline ballast water. This is of great significance for the scientific management of ballast water discharge in fresh waters in the future.

“…This process produces chlorine by adjusting the applied potential or current in the system. However, the main disadvantage of chlorine-based disinfection methods is the remaining chlorine content in the water, which can create undesirable byproducts. , Due to the large production of byproducts in the disinfection process, exposure to these compounds through the direct use of water, inhalation and skin absorption during showering and swimming poses a serious risk to human health due to their potential carcinogenicity. The lethal effect of the remained free chlorine in the disinfected seawater also has broad influence on the aquatic organism or estuarine ecosystems due to the reaction of free chlorine with organic compounds in seawater .…”

Disinfection-Dechlorination Battery for Safe Water Production

et al. 2021

With increasing population growth, it is necessary to meet safe water demands. Water disinfection through chlorination is the most commonly used method for safe water production. The electrolysis of salted water is a promising technology for the on-site generation of disinfecting agents, however, its low efficiency and inability to neutralize the remaining free chlorine makes electrolysis inefficient. The introduction of a cation permeable membrane between anode and cathode can help to improve the disinfection efficiency and also dechlorinate the remained free chlorine by switching the anode and cathode. However, the scale formation on the membrane will reduce the performance of the system. In this study, with using a Na-selective membrane for separating anode and cathode, we propose a disinfection-dechlorination battery (DD-battery) consisting of an anode for energy storage through Na + reduction to metal Na and a cathode for disinfection via Cl − oxidation to free chlorine species. The stored energy in the anode is released during discharge, and the system can dechlorinate the remaining free chlorine to prevent disinfectant toxicity. This self-disinfectiondechlorination during battery cycling can be combined with renewable energy sources for efficient water disinfection in remote regions.
