“…Furthermore, higher stability of process performances of AnMBR over UASB was reported to overcome high salinity [34]. Elevated TMP values were also reported by Yurtsever et al [19] with respect to high salinity conditions. The salinity induced large molecules as foulants in gel/cake layer, that may originate from biomass loosely bound EPS.…”

“…For instance, salinity increase from 8 20 gNa + .Lto 20 gNa + .L -1 was accompanied by the increase of the transmembrane pressure (TMP) up to 350 mbar, while a ten-fold reduction in biomass particle size resulted in a filtration resistance increase [18]. Similarly, Yurtsever et al [19] indicated that salinity induced large molecules, to be detected as foulants in gel/cake layer; they may originate from biomass loosely bound extracellular polymeric substances (EPS). Secondly, saline conditions can suppress microbial growth and cause the disintegration of flocs and granules that further lead prominent biomass wash-out affecting the sludge granulation [20].…”

Long term operation of an anaerobic membrane bioreactor (AnMBR) treating municipal wastewater was investigated in a real seawater intrusion spot in Falconara Marittima (Central Italy) on the Adriatic coastline. Changes in biological conversion and system stability were determined with respect to varying organic loading rate (OLR) and high salinity conditions. At an OLR of 1 kgCOD . m 3-1 d -1 , biogas production was around 0.39 ± 0.2 L . d -1 . The increase of the OLR to 2 kgCOD . m 3-1 d -1 resulted in the increase of biogas production to 2.8 ± 1.5 L . d -1 (with 33.6% ± 10.5% of CH4) with methanol addition and to 4.11 ± 3.1 L . d -1 (with 29.7% ± 11.8% of CH4) with fermented cellulosic sludge addition. COD removal by the AnMBR was 83% ± 1% when the effluent COD concentration was below 100 mg O2 . L -1 . The addition of the fermented sludge affected the membrane operation; significant fouling occurred after long-term filtration, where the trans-membrane pressure (TMP) reached up to 500 mbar. Citric acid solution was applied to remove scalants and the TMP reached the initial value. High saline conditions of 1500 mgCl -. L -1 adversely affected the biogas production without deteriorating the membrane operation. The treated effluent met the EU quality standards of the D.M. 185/2003 and the new European Commission Resolution for reuse in agriculture.

“…The additional amount of dye with high concentrations of salt in wastewater increases environmental contamination (Dodangeh & Gharanjig, 2012). According to different resources, salt range of textile wastewater is varied between 1000 and 10,000 mg/L (Salvadó, Mas, Menéndez, & Gracia, 2001;Yurtsever, Calimlioglu, Görür, http://dx.doi.org/10.1016/j.jart.2017.01.012 1665-6423/© 2017 Universidad Nacional Autónoma de México, Centro de Ciencias Aplicadas y Desarrollo Tecnológico.

Textile wastewater is a combination of various chemicals and different types of dyes and has a salty nature. In this study, an SBR (sequencing batch reactor) was used to treat synthetic and real textile wastewaters in a 24 h cycle time. Remazol Brilliant Blue R, a reactive dye, was used as the model dye. Dye concentrations ranged from 125 mg/L to 500 mg/L, and TDS (total dissolved solids) concentrations ranged from 1000 mg/L to 10,000 mg/L in synthetic wastewaters. For the highest dye concentration (500 mg/L) with low TDS, an 80.71% COD removal efficiency was obtained; at a TDS concentration of 5000 mg/L, a 59.44% COD removal efficiency was obtained. When the TDS concentration of wastewater was raised to 10,000 mg/L, COD removal decreased to 14.92% and reductions in MLSS (mixed liquor suspended solids) and MLVSS (mixed liquor volatile suspended solids) concentrations were observed. According to the results, increasing the TDS concentration of wastewater up to 5000 mg/L did not affect COD removal efficiency of the activated sludge microorganisms in the treatment system.
