“…On average 80.2% ±28.1% of the As(III) was rejected with a maximum feed concentration of 180 g/L. Plants ranging in size from centralized treatments to smaller systems for individual households have been studied intensively [13][14][15][16]. However, specific recommendations for arsenic waste disposal are often lacking or mentioned as an area for future research.…”

“…However, the As(III) removal efficiency of NF membranes is very low and cannot match the permissible limit of As at higher feed concentrations, hence pre-oxidation to As(V) is needed [12]. Recent studies showed the successful treatment of arsenic by reverse osmosis (RO) [13][14][15][16]. The arsenic removal efficiency by RO depends on its species.…”

“…On the other hand, more regulations on effluent water quality have resulted in that boron and arsenic are becoming of main interests since they are typically difficult to remove by RO. Despite the recent advances of membranes, boron (Br) and arsenic (As) rejection remains low in comparison to other inorganic components, such as sodium chloride (Teychene et al 2013). In addition to removal of inorganic ions, co-removal of organic matter in brackish water has been the focus of intense scientific and practical efforts.…”

In this article, we present a critical review of the reported performance of reverse osmosis (RO) and capacitive deionization (CDI) for brackish water (salinity < 5.0 g/L) desalination from the aspects of engineering, energy, economy and environment. We first illustrate the criteria and the key performance indicators to evaluate the performance of brackish water desalination. We then systematically summarize technological information of RO and CDI, focusing on the effect of key parameters on desalination performance, as well as energy-water efficiency, economic costs and environmental impacts (including carbon footprint). We provide in-depth discussion on the interconnectivity between desalination and energy, and the trade-off between kinetics and energetics for RO and CDI as critical factors for comparison. We also critique the results of technical-economic assessment for RO and CDI plants in the context of large-scale deployment, with focus on *Manuscript Click here to view linked References 2 lifetime-oriented consideration to total costs, balance between energy efficiency and clean water production, and pretreatment/post-treatment requirements. Finally, we illustrate the challenges and opportunities for future brackish water desalination, including hybridization for energy-efficient brackish water desalination, co-removal of specific components in brackish water, and sustainable brine management with innovative utilization. Our study reveals that both RO and CDI should play important roles in water reclamation and resource recovery from brackish water, especially for inland cities or rural regions.

“…Increasing the pH value overcomes the dissociation constant value provides remarkable tolerance against every species, including metalloids. The research examined that the rejection of As (III) was 99% in brackish water membranes and SWRO membrane at pH = 9.6 and 40 bars and pH = 7.6 and 24 bars, respectively 53 . Studies showed that the high salinity and the temperature conditions in gulf countries overcome pH adjustment.…”

This article highlighted some pretreatment methods to get potable water from Seawater. In the twentieth century, the ever-spreading urbanization and rapid increase in industrialization coupled with contamination of natural water sources through unprecedented use of chemicals have raised the demand for good quality drinkable water. The anthropogenic activities are continuously disturbing the physical, chemical, and biological composition of aquatic biota. To meet the demand of potable water, the process of Seawater Reverse Osmosis (SWRO) is now being used in developed countries. SWRO is a technique that removes all types of impurities, whether suspended or dissolved, including bacteria. This mini-review discusses some essential pretreatment parameters like pH, conductivity, turbidity and ionic strength which are involve in SWRO to convert Seawater into drinkable. Pakistan is now in line with other countries to install SWRO plants to remove water scarcity, especially in big cities like Karachi.
