“…1. Casting solution was prepared according to the procedures described previously [36,37], with a recipe containing 17 g of PVDF (Solef 6010, Solvay S.A., Belgium), 0.5 g of polyvinylpyrrolidone (PVP, MW ~40 kDa, Amresco), and 82.5 g of N-methy-2-pyrrolidone (NMP, Sinopharm Chemical Reagent Co., Ltd, China). To fabricate the membranes, a liquid film of the casting solution was applied onto a glass plate at a thickness of 250 ȝm using a doctor blade (Elcometer 3530, UK).…”

“…Wastewater Type I consisted of different solutions of each pharmaceutical compound in deionized water, whereas wastewater Type II is similar to Type I but adding bovine serum albumin (BSA) in its composition. According to Liang et al, this second model wastewater simulates a real wastewater from WWTP [48]. UF experimental set up was described previously in detail in a previous paper [49].…”

a b s t r a c tRecently, there is an emergence of endocrine-disrupting compounds, pharmaceuticals, and personal care products (EDC/PPCPs) as important pollutants to remove from drinking water and reclaimed wastewater. In this work, the efficiency of removing pharmaceuticals (PCs) from model aqueous solutions and raw wastewater with ultrafiltration (UF), nanofiltration (NF), activated carbon adsorption (AC), biological methods (SBR) and oxidation with ClO 2 was investigated. Some treatments have also been used as combined processes: UF + NF, UF + AC, SBR + ClO 2 . Ibuprofen, Acetaminophen, Diclofenac, Sulfamethoxazole, Clonazepam, and Diazepam were selected as model compounds. In order to evaluate their removal, PC solutions were also considered at several operating conditions (pH, conductivity, concentration, and temperature), and optimal conditions were obtained. Experiments were performed at usual PC concentrations in wastewaters: 1000 ng/L for Ibuprofen and Acetaminophen, 300 ng/L for Diclofenac, Sulfamethoxazole, Clonazepam, and Diazepam. Separation was evaluated by liquid chromatography-mass spectroscopy. Results indicated that the removal efficiency depends on their Log K OW , which is intrinsically related to their hydrophobicity and then, to their adsorption onto the surface (UF, NF, and AC). Also, NF, AC, and combined processes (UF + NF, UF + AC) were the most suitable separation techniques to obtain high removal efficiencies for most of the PCs used, except for Acetaminophen (which showed great removal efficacy using SBR). UF presented low removal yields for all PCs tested. ClO 2 treatment was more effective at high concentration (50 mg ClO 2 /L). Furthermore, results also showed that there are significant differences on the performance of the processes applied and which treatment is the most effective for each PC analyzed.

“…Up to now, there are more than 50 manufacturers in the Chinese market [29]. International corporations include Mitsubishi Rayon (Japan), Kubota (Japan), Asahi Kasei (Japan), Memstar (Singapore), GE (USA), Canpure (Canada), Siemens The prevailing membrane materials used for MBR are halogenated hydrocarbon polymers like polyvinylidene fluoride (PVDF), due to their superior properties in mechanical strength, chemical tolerance, and biological stability [1,30,31]. Other organic polymer materials such as polyethylene (PE), polypropylene (PP), and polyether sulfone (PES) are also in use [1].…”

China has been the forerunner of large-scale membrane bioreactor (MBR) application. Since the first large-scale MBR (≥10 000 m 3 $d -1 ) was put into operation in 2006, the engineering implementation of MBR in China has attained tremendous development. This paper outlines the commercial application of MBR since 2006 and provides a variety of engineering statistical data, covering the fields of municipal wastewater, industrial wastewater, and polluted surface water treatment. The total treatment capacity of MBRs reached 1 Â 10 6 m 3 $d -1 in 2010, and has currently exceeded 4.5 Â 10 6 m 3 $d -1 with~75% of which pertaining to municipal wastewater treatment. The anaerobic/anoxic/aerobic-MBR and its derivative processes have been the most popular in the large-scale municipal application, with the process features and typical ranges of parameters also presented in this paper. For the treatment of various types of industrial wastewater, the configurations of the MBR-based processes are delineated with representative engineering cases. In view of the significance of the cost issue, statistics of capital and operating costs are also provided, including cost structure and energy composition. With continuous stimulation from the environmental stress, political propulsion, and market demand in China, the total treatment capacity is expected to reach 7.5 Â 10 6 m 3 $d -1 by 2015 and a further expansion of the market is foreseeable in the next five years. However, MBR application is facing several challenges, such as the relatively high energy consumption. Judging MBR features and seeking suitable application areas should be of importance for the long-term development of this technology.
