“…Desalination is well established in 1 some countries, and reuse is considered to be an alternative (Côté et al, 2005). The 2 growth of desalinated water production worldwide is near exponential (Dawoud, 3 2005), which might be explained by the declining costs of desalination technology, 4 even though it produces water more expensively than does traditional supply 5 (Dawoud, 2005). 6 Key issues in the desalination debate concern energy consumption, water 7 quality, and environmental impacts.…”

Many countries' water resources are limited in both quantity and quality. While engineering solutions can now safely produce recycled and desalinated water from non-potable sources at a relatively low cost, the general public is sceptical about adopting these alternative water sources. Social scientists need to better understand what is causing this lack of acceptance by the general population and how acceptance levels for recycled and desalinated water can be increased. This study is the first to conduct a comparative analysis of knowledge, perceptions, acceptability, and determine segments of residents who are more open-minded than the general population toward the use of recycled and desalinated water. The Australian population once perceived desalinated water as environmentally unfriendly, and recycled water as a public health hazard. The general level of knowledge about these two concepts as potential water sources has historically been low. After nearly five years of serious drought, accompanied by severe water restrictions across most of the country, and subsequent media attention on solutions to water scarcity, Australians now show more acceptance of desalinated water for close-to-body uses, and less resistance to recycled water for garden watering and cleaning uses. The types of people likely to be strong accepters of the two alternative water sources are distinctly different groups, and can be reached through different media mixes. This finding has significant implications for policy makers.

“…Most desalinated water producing cities such as Sidney (Australia), California (United States), Beijing (China), Larnaca (Cyprus), Tripoli (Algeria), Jubal (Saudi Arabia), etc., are coastal cities. The dominant cost is the desalination, not transport (Dawound, 2012 …”

“…At the intake, the marine algal toxins enter in either dissolved (extracellular, C E0 in µg/L) or particulate (intracellular, C I0 in pg/cell) forms. The mass flow of intracellular (M I0 ) and extracellular toxins (M E0 ) entering the facility is calculated using Equations (1) and (2).…”

“…As the stress increases on existing surface freshwater supplies due to population growth, agricultural development, global climate change, and industrial expansion, SWRO has become a more accepted approach to augment the world's existing freshwater supply, especially in arid regions such as the Middle East [2,3]. Coupled with recent advances in membrane technology and sustainable sources of energy for operation (such as solar or wind power), SWRO is transitioning from a viable alternative to an integral component of freshwater provisions for many coastal municipalities and industries worldwide [4][5][6][7].…”

Abstract:The operation of seawater reverse osmosis (SWRO) desalination facilities has become challenged by the increasing frequency and severity of harmful algal blooms (HABs). The efficiency of algal toxins removal during SWRO and pretreatment processes has critical human health implications. Therefore, a probabilistic materials flow analysis (pMFA) was developed to predict the removal of algal toxins in source water by various pretreatment configurations and operations during SWRO desalination. The results demonstrated that an appreciable quantity of toxins exists in the SWRO permeate (ng/L-µg/L levels), the backwash of pretreatment, and final brine rejects (µg/L-mg/L levels). Varying the pretreatment train configuration resulted in statistically significant differences in toxin removals, where higher removal efficiencies were evidenced in systems employing microfiltration/ultrafiltration (MF/UF) over granular media filtration (GMF). However, this performance depended on operational practices including coagulant addition and transmembrane pressures of MF/UF systems. Acute human health risks during lifetime exposure to algal toxins from ingestion of desalinated water were benign, with margins of safety ranging from 100 to 4000. This study highlights the importance of pretreatment steps during SWRO operation in the removal of algal toxins for managing marine HABs.
