“…Therefore, to satisfy the broad demands for high quality reclaimed water, further advanced treatment technologies, such as membrane technology, are desperately needed. Membrane processes, such as ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO), have been widely applied in wastewater treatment and reuse (Jacob et al, 2010;Lau and Ismail, 2009). The UF process could not meet with the requirements for chemical oxygen demand (COD), nitrogen and phosphorus in the new Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant in Beijing (DB11/890-2012), whose requirements are similar to those of the surface water Class IV standard (GB 3838-2002) (except the limit for total nitrogen).…”

“…It is generally believed that an appropriate pretreatment process could be a key factor for the steady performance of NF or RO in wastewater treatment, especially the sort of wastewater with high contents of organic matters, total dissolved solids (TDS), and suspended solids (SS) (Alturki et al 2010;Huang et al 2009;Jacob et al 2010;Ordóñez et al 2011). It was found that the deployment of MBR as a pretreatment prior to NF/RO could effectively reduce the membrane fouling of NF/RO.…”

“…Membrane technologies, such as microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO), have been widely applied in wastewater treatment and reuse (Alturki et al 2010;García-Figueruelo et al 2008;Jacob et al 2010;Lau and Ismail 2009). Considering the large pore size of MF and UF which lead a low rejection rate of micropollutants in the wastewater, many studies turned their focus on NF and RO for the applications in the advanced treatment and reclamation of industrial wastewater because of their high efficiency in desalination and steady performance (Al-Rifai et al 2011;Andrade et al 2014;Baudequin et al 2014;Michael et al 2013;Ravikumar et al 2014).…”

The optimization of the nanofiltration (NF) concentrate backflow ratio (R cb ) and the influence of the NF concentrate on the performance of membrane bioreactornanofiltration (MBR-NF) process treating antibiotic production wastewater were investigated on a laboratory scale. The R cb was optimized at 60 % based on the removal rates of chemical oxygen demand (COD) and NH 4 + -N by MBR. Data analyses indicated that salinity brought by NF concentrate is the major driver leading to the decrease of sludge activity, especially at a high R cb . EPS analysis showed that electric conductivity (EC), proteins in soluble microbial products (SMP), and SMP brought by NF concentrate are the dominant factors causing the severe membrane fouling in MBR. Furthermore, undegradable substances including fulvic acid-like and humic acid-like compounds accumulated in NF concentrate showed significant influence on fouling of NF. MBR could well degrade small MW compounds in NF concentrate, which confirmed the enhancement of organic removal efficiency by recycling the NF concentrate to MBR. The MBR-NF process showed a relatively stable performance at the R cb of 60 % (volume reduction factor (VRF) = 5), and the NF permeate could satisfy the water quality standard for fermentation process with a water recovery rate of 90.9 %.

“…However, if a higher water quality level is required, such as water for indirect potable reuse or industrial reuse, a tertiary treatment, such as nanofiltration or reverse osmosis, could be necessary (Brik et al, 2006;Jacob et al, 2010). Nanofiltration (NF) is an intermediary process between ultrafiltration and reverse osmosis.…”

“…Moreover, it has lower pressure requirements and higher flux compared to reverse osmosis (Suksaroj et al, 2008). Studies show that NF is an efficient treatment system for secondary or tertiary effluents aiming at the generation of water for industrial, agricultural, or indirect potable reuse (Koyuncu et al, 2000;Dresch et al, 2001;Shu et al, 2005;Acero et al, 2010;Jacob et al, 2010;Luo et al, 2011;Riera et al, 2013;Andrade et al, 2014).…”

-This study evaluated the technical and economic feasibility of membrane bioreactors (MBR) followed by nanofiltration (NF) for dairy wastewater treatment in order to reuse the treated effluent. It was observed that the MBR efficiently removed the organic matter and color of the feed effluent; however, due to the high concentration of dissolved solids in the permeate, it was necessary to use nanofiltration as a polishing step. The final treated effluent could be reused in the industry for cooling, steam generation and cleaning of external areas. A preliminary economic analysis showed the feasibility of the proposed system. The internal rate of return was greater than or equal to 32% when membrane lifespan was at least 2 years and the depreciation time was 15 years. The total cost of the proposed treatment system ranged from R$ 9.99/m³ to R$ 6.82/m³, depending on membrane lifespan.
