“…Process modeling of an FO-RO system [103] and bench-scale testing of both FO-RO [104] and FO-NF [21] systems have demonstrated the practicability of implementing FO as a pretreatment process. The potential benefits of FO pretreatment for achieving higher system recoveries in membrane desalination were demonstrated by pilot-scale studies of brackish water desalination with ion exchange pretreatment [105] and seawater desalination with NF pretreatment [106]. The advantage of FO pretreatment over ion exchange or NF, in addition to the lower fouling propensity, is the ability to remove all dissolved species from the feed water, not just specific cations or anions.…”

“…INTRODUCTION Preventing mineral scale build-up (such as calcium carbonate and barium sulphate) is an important challenge in many industrial installations such as desalination plant, heat transfer equipment or oil production facilities [1][2][3][4][5][6]. Mineral scale fouling costs money by reducing the efficiency of systems, and can in the worst case scenario result in safety hazards [7].…”

Preventing mineral fouling, known as scale, is a long-standing problem for a broad range of industrial applications ranging from oil production to water treatment systems to names 2 but a few. The build-up of inorganic scale such as calcium carbonate on surfaces and facilities is undesirable as it can result in safety risks and associated flow assurance issues. To date the overwhelming amount of research has mainly focused on chemical inhibition of scale bulk precipitation and little attention has been paid to deposition onto surfaces. The development of novel more environmentally-friendly strategies to control mineral fouling will most probably necessitate a multifunctional approach including surface engineering. In this study, we demonstrate that liquid infused porous surfaces provide an appealing strategy for surface modification to reduce mineral scale deposition. Microporous polypyrrole (PPy) coatings were fabricated onto stainless steel substrates by electrodeposition in potentiostatic mode. Subsequent infusion of low surface energy lubricants (fluorinated oil Fluorinert FC-70 and ionic liquid 1-Butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (BMIm) ) into the porous coatings results in liquid-repellent slippery surfaces.To assess their ability to reduce surface scaling the coatings were subjected to a calcium carbonate scaling environment and the scale on the surface was quantified using Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES). PPy surfaces infused with BMIm (and Fluorinert to a lesser extent) exhibit remarkable antifouling properties with the calcium carbonate deposition reduced by 18 times in comparison to untreated stainless steel. These scaling tests suggest a correlation between the stability of the liquid infused surfaces in artificial brines and fouling reduction efficiency. The current work shows the great potential of such novel coatings for the management of mineral scale fouling.

“…Water scarcity has become a global risk and one of the most serious concerns for the scientific community as a result of increasing population, continuing industrialization, expanding agricultural activities, increasing inequities between water supply and demand, improper management and degradation of natural water resources, and increasing regional and international conflicts [1][2][3][4][5][6][7][8]. Recent statistics show that approximately 15% of people around the world lack access to drinking water and 36% of the world's population suffer from water scarcity for at least one month of a year [9].…”
