“…In addition, high salt concentration causes more EPS and SMP production due to the incomplete degradation of organic substances and the release of cell contents to protect microbial cells from salt toxicity . All these changes eventually result in membrane fouling due to increasing pore blocking resistance …”

“…Nevertheless, Sun et al reported that a better membrane performance with a lower membrane fouling rate can be achieved through longer acclimated times at high salt concentrations. Microorganisms named halophilic microorganisms or halophiles can biodegrade organic matters from saline water since they require a certain amount of salt to grow.…”

“…Currently, ceramic membranes, textile materials, and non‐woven meshes are being successfully used for several MBRs due to better chemical, physical, thermal and hydraulic resistances, higher integrity, longer lifespan, and effective fouling control, in comparison to polymeric membranes. However, they cannot be widely used due to their higher costs …”

Membrane bioreactors (MBRs) have been widely used for municipal and industrial wastewater treatment around the world due to their advantages, which include higher efficiency, smaller footprint, and lower sludge production over other conventional activated sludge (CAS) processes. However, membrane fouling that results from physicochemical interactions between the membrane and the components of the mixed liquor still remains the most challenging matter preventing the broad application of MBR technology. Recently, a considerable number of experimental and modelling investigations have been conducted concerning MBRs and membrane fouling. Despite the development of low‐fouling membrane systems, more research and engineering activities with a focus on surface modification, wastewater specifications, pre‐treatment and treatment conditions, and efficient fouling control and remedy strategies are still needed to minimize the probability of the occurrence of fouling. It is vital to investigate important aspects of the characterization and mechanisms of the fouling phenomenon to find reliable and long‐term solutions. This review provides a detailed survey of the main aspects of the MBR processes, configurations, advantages and disadvantages, fouling phenomenon, and fouling control strategies in MBRs. Past research and engineering activities in this area are critically reviewed such that pros and cons of recent developments in fouling inhibition and mitigation approaches are also discussed. The main practical and theoretical challenges for the effective utilization of MBRs in various municipal and industrial sectors are then addressed. At the end, we offer useful practical guidelines and recommendations for the better design and operation of MBRs in industrial and public communities.

Bilge water treatment was studied in an upflow electrochemical reactor (UECR) in order to design a compact onboard wastewater treatment system. The influence of retention time on the removal efficiencies of chemical oxygen demand (COD) and turbidity were analyzed, and optimized using response surface methodology (RSM) for maximizing the removal efficiencies. The best operating performance was obtained at 390 min retention time and 480 min reaction time for cost effective analysis with the composition of 100% bilge water (COD o ¼ 3080 mg/L) and 50/50% seawater/fresh water, 12.8 mA/cm 2 current density, and 32 C reaction temperature. Under response surface optimized conditions, the responses were estimated as; 90% COD removal, 97% turbidity removal, outlet pH value of 8.1, mass transfer coefficient of 0.494 Â 10 À5 m/s, and mean energy consumption of 44.8 kWh/kg COD removed.

“…In addition, the fibre filter as an alternative filter to conventional pretreatment filter has been studied for feasible application in seawater pretreatment process [7,8]. The biological aerated filter (BAF) was found to effectively remove the organic and Downloaded by [UNAM Ciudad Universitaria] at 15:05 27 December 2014 nutrient as well as particulate matter in seawater [9] and saline wastewater [10]. An efficient pretreatment must be designed to face the worst water quality and provide a constant and good quality of feed water to seawater reverse osmosis (SWRO) [11].…”

To cite this article: Kil-Soo Hyun (2011) Configuration of an efficient seawater pretreatment system for simultaneous organic and particulate matters removal, Desalination and Water Treatment, 33:1-3, 295-299, ab s t r ac tIn this study, the high-rate fibre filter (HRF) using the fibre media and the biological aerated filter (BAF) followed by granular media filter (GMF) using anthracite and granular activated carbon (GAC) was evaluated as an effective pre-treatment for simultaneous organic and particulate matter removal. As a result, the HRF bed was more effective in reducing particulate matters, while the BAF bed was effective in reducing conventional pollutants as well as particulate matters. The performance results of combined HRF/BAF/GMF system in terms of pollutants and headloss achieved 12-35% higher reduction and about 1.7 times slower development than those of the combined HRF/ GMF system. The performance of combined HRF/BAF system (FV 30/3 m/h) followed by GAC filter (FV 5 m/h) showed an excellent removal results of >80% for organics and nutrients and >90% for particulate matters, which typically cause membrane biofouling and colloidal fouling. This reveals that combined HRF/BAF/GMF system is an effective pretreatment system to control and reduce the extent of membrane fouling compared to conventional coagulation-granular filtration.
