“…The use of ozone, flocculants, hydrogen peroxide, lime and chlorine requires special precautions for safety purposes. Each step of this process has to be controlled to get an optimal performance of the overall process, which results in a complex control system (79,80). Pre-treatment chemicals may include chlorine, ferric chloride bisulfate coagulant, sulphuric acid, sodium meta bisulfate and anti-scalant (81).…”

Recent advances in membrane technology have prompted the rapid growth of the Reverse Osmosis (RO) desalination in comparison to other water desalination technologies. One of the major problems of RO is fouling which leads to major reduction in the efficiency of this process. RO membranes are usually fouled with colloids, humic substances, micro-organisms, and heavy metals. This is why it is critical to treat the feed water prior to RO filtration. Conventional pre-treatment methods include processes such as coagulation, adsorption, sedimentation, flotation, sand filtration, disinfection, and the addition of anti-scalants. Recently, membrane pre-treatment processes including micro-filtration (MF), ultrafiltration (UF) and nanofiltration have been introduced prior to RO, with or as a replacement for conventional pre-treatment. These processes are useful in providing feed water superior in quality to conventional pre-treatment, but they are limited in the range of pollutant removal and operating conditions. Full description of water composition and the interactions and aggregations between the contaminants found in feed water for RO desalination is shown in this review. The review includes introduction to membranes, including 403 Downloaded by [University of Cambridge] at 12:12 03 December 2014 retention and fouling mechanisms, conventional and membrane pre-treatment, and membrane backwashing. It also highlights the role of coagulation and adsorption in the pre-treatment process and the impact of integration of coagulation and/or adsorption with membrane pre-treatment.

“…In the steel sector, electrodialysis and ion exchange have been applied for the treatment of wastewater from rinsing of stainless steel etched in nitric acid and hydrofluoric acid [10]. In addition, the combination of ultrafiltration (UF) and RO has been tested for producing deionised water from surface waters [11]. A more efficient application of RO can be achieved through the combination with a pre-treatment, such as back-washable microfiltration (BMF) [12].…”

Abstract:In the steel sector water management aims at improving the sustainability of the production cycle, resulting in resource efficiency benefits and in reduced water demand and costs. To be reused, water needs to be cooled and desalinized to avoid salt concentration in water circulation systems. The presented work includes two case studies carried out in an integrated steelmaking plant, respectively, to evaluate the possible implementation of ultrafiltration and reverse osmosis to reduce salt concentration in water streams and to investigate, through modelling and simulation, a process integration solution to improve water efficiency. Results showed that most salts are removed by reverse osmosis and that its coupling with ultrafiltration allows obtaining very high quality water; reuse of desalinated wastewater resulted in being more suitable and economically viable than its discharge. Moreover, modelling and simulation showed that the considered blowdown could be reused without significant changes in the receiving water network area. The industrial implementation of water recovery solutions can lead to a decrease of fresh water consumption, effluent discharge, and to improvement of product quality and equipment service life. The considered desalination technologies are transferable and easily implementable, and modelling and simulation are very useful in order to evaluate process modifications before real implementation.

A B S T R A C TIn recent years, membrane-based ultrafiltration (UF) and reverse osmosis (RO) have become popular worldwide as possible alternative methods to conventional ion exchange and clarification processes for the production of potable water. The performance of UF and RO membranes was evaluated for treatment of surface and ground water from Prakasam District of Andhra Pradesh, India; namely, jagarlamudi well water (JWW), jagarlamudi pond water (JPW), veerannapalem old pond water (VOPW), and veerannapalem new pond water (VNPW). Pilot-scale UF and RO systems were built indigenously by incorporating commercial hollow fiber polyacrylonitrile UF and thin film composite polyamide RO modules, respectively. Operating parameters such as feed concentration, pressure, and cross-flow velocity were varied to study their effect on membrane performance. Effect of fouling on flux and rejection characteristics of the membrane was evaluated. RO membrane exhibited a rejection of 96.4% for JWW and VOPW feeds with reasonable flux of 42.5 and 48 L m À2 h À1 , respectively, whereas, UF experiments with JPW and VNPW feeds revealed corresponding turbidity rejections of 95.6 and 98.2%. A mathematical model was developed for commercial RO system to simulate the process for establishing optimum operating conditions. A comparison of UF and RO processes for this application is presented along with useful details of equipment list, process flow diagram of commercial membrane plant, schematic of compact hollow fiber pilot plant, and detailed estimation of operating costs.
