“…Potential issues with this technology were identified due to elevated levels of dissolved "reactive" silica. 60 Activated alumina has a higher affinity for silica than both arsenic and fluoride, indicating the media might be filled with silica before fluoride or arsenic. An elevated silica concentration would also diminish RO water recovery.…”

Brackish water is a widely available, nontraditional water resource that can augment limited freshwater supplies. Although brackish water desalination has been continuously implemented in the United States and worldwide, it is necessary to reduce further its energy consumption, costs, and environmental impacts. This study conducted technoeconomic analyses to evaluate the current desalination and brine management technologies, focusing on the key factors and opportunities for sustainable brackish water desalination for municipal uses. Three case studies were selected as baseline representative of different geographic and operational conditions, including water quality, plant size, pretreatment, desalination, and concentrate management. The technoeconomic analyses and model simulations identified challenges, opportunities, and research priorities to achieve specific pathways for enhanced brackish water desalination regarding levelized costs of water, electricity intensity, water recovery, zero liquid discharge, and brine valorization.

“…The total cost to build Irwin in 2016 was $100.1 million − $51 million for the water treatment and $49.1 million for the brine management. 60 The high recovery processes in brine treatment, not common in municipal applications, had almost doubled the capital cost, with increased operating costs.…”

“…The media filter processes are designed to be a pretreatment, removing constituents that could compromise the polishing and final processes, which is a six stage reverse osmosis system. The reverse osmosis (RO) system provides high rejection of organic and inorganic contaminants (Medina et al 2012;Medina et al 2015), including chemical warfare agents and radioisotopes. Detailed information on the DETS is provided in three previous publications (Dedeaux and Medina 2017;Medina et al 2018aMedina et al , 2018bMedina 2019).…”

A previous ERDC report described the effectiveness of the Decontamination Effluent Treatment System (DETS) for the treatment of wash water generated from simulated CBRN decontamination. This study compliments that previous one in that it focused on the treatment of a simulant from Mass Personnel Decontamination (MPD). Treatment of both cesium 133 (used as a surrogate for radioactive cesium 137) and Malathion (as a surrogate for organophosphate chemical warfare agent) equaled or exceeded 99.95%. The conclusion was that the system proved to be highly effective at treating wash water from MPD, which would allow discharge or even potential reuse for more decontamination. The ERDC team conducted studies that confirmed that the DETS could be integrated into CERFP activities with minimal disruption. In addition, the DETS underwent a long road test in which it was driven for over 1000 miles from Vicksburg MS to St Robert MO (Fort Leonard Wood) and back. The conclusion is that the DETS could be moved around the United States as needed to respond to decontamination events. The DETS was also used to treat PFOS, a perfluorinated compound found in legacy firefighting foams, and the DETS processes achieved 99.97% removal of ~30 µg/L PFOS.

“…Nonetheless, attention in the treatment or removal of inorganic matter from the aqueous system has to be paid to the destination of the generated concentrate, retentate, brines, or sludge containing the removed ingredients in general. The electrochemical methods have been tested, e.g., frequently for the treatment of retentate of RO or as a pretreament step . For the treatment of these so‐called hard‐to‐treat streams, electrochemical methods show a high potential to fit into this niche .…”

Electrochemical technologies for the treatment of industrial and municipal wastewaters, potable water, and groundwater, are presented, focusing on the main water constituents: inorganics, organics, micropollutants, and microorganisms. Removal of inorganic compounds by electrodialysis, electrocoagulation, and capacitive deionization as well as removal of organics and micropollutants by electrosorption, advanced oxidation processes, and anodic oxidation with boron‐doped diamond electrodes are reviewed. Electricity can be generated by degradation of organic compounds in microbial fuel cells and dehalogenation by cathodic reduction minimizes toxic substances in water. The disinfection of different types of water is also presented and it is shown that electrochemical methods offer versatile approaches to contribute to an sustainable future water management.
