“…Coagulation may not be needed in every case. The need for coagulants and the optimum dosage should be established by pilot testing [114], as overdosing may cause operational problems of the prefiltration membranes [91] or the SWRO membranes [123], and would represent an unnecessary cost factor and environmental burden. The majority of UF/MF systems also used chlorine, either continuously in the UF feedwater or intermittently in the UF feed or backwash water.…”

“…Chlorine levels in CEB varied between 5-20 mg/l every 15-40 minutes [i.e., every backwash, 98,99,101,119,123], to 20-50 mg/l every 2-6 hours [112,117], up to 100-500 mg/l once or twice per day [98,100,102,107,110,120,121]. These values show a higher upper range than the results of a review carried out by Fritzmann et al [126], who reported chlorine levels of 10-200 mg/l in CEB of UF/MF membranes.…”

“…once a day, the water loss is 5%. For example, two conventional pretreatment systems in the Mediterranean and Red Sea were operated with water losses of 4% and 4.4% for backwashing, respectively [123]. The water losses in UF/MF pretreatment are generally higher than in conventional pretreatment due to a higher backwashing frequency of normally at least once per hour.…”

“…Over the last decade, UF membranes have been tested and applied at pilot and commercial scale as pretreatment for SWRO (Rosberg, 1997;van Hoof et al, 1999;Brehant et al, 2002;Glueckstern et al, 2002;Wolf et al, 2005;Halpern et al, 2005;Gille and Czolkoss, 2005) and are reported to offer several advantages over conventional pretreatment systems; namely, lower footprint, constant high permeate quality (in terms of SDI), higher retention of large molecular weight organics, lower overall chemical consumption, etc. (Wilf and Schierach, 2001;Pearce, 2007).…”

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.
