“…Furthermore, both NF and RO in the study also demonstrated a high removal rate (>80%) of compounds that persist through MBR including DEET, Atrazine, Meprobamate, Primidone, and Dilantin. This result is strongly supported by another MBR-NF/RO evaluation, where 27 common antibiotics and pharmaceuticals were tested, showing an excellent removal rate of the system for all compounds (95% on average) and a high removal rate (>50%) of NF for Metoprolol, Norfloxacin, Enrofloxacin, and Carbamazepine compounds [19]. With regard to the removal of pathogens, NF has been shown to be able to remove Bacillus subtilis bacteria and MS2 bacteriophage at very high efficiencies, ranging from 3.3 to 6.3 log removal value (LRV) for Bacillus subtilis bacteria and from 4.1 to 4.5 LRV for MS2 bacteriophage [20].…”

Hospital wastewater contains pharmaceutical residues, chemicals, and pathogens that cause coloration and nourish pathogenic microorganisms. The objective of the study was to evaluate the effectiveness of a medical wastewater treatment system at Military Hospital 175 (Ho Chi Minh City, Vietnam) that combined a membrane bioreactor (MBR) system with nanofiltration (NF). The influent of the system was the wastewater discharged from the operating rooms of the hospital. The system has a capacity of 50 L/day and operates at three organic load rates (OLR) of 0.5, 1.5 and 2.5 kgCOD/m3day (COD: Chemical oxygen demand), in which each load rate operates for 40 days. The results showed that most nutritional criteria generally achieved positive results. Specifically, the average COD removal was shown to be consistently high throughout the three phases at 94%, 93.3%, and 92.7%, respectively. For removal of nitrogen, the system demonstrated efficiencies of 75%, 79%, and 83%, respectively, to three phases. The log removal value (LRV) for Escherichia coli and coliform bacteria were higher than four throughout the study period. The average removal efficiency for color and total iron was approximately 98% and 99%, respectively. The water quality after treatment, especially after NF, meets the Vietnamese standard of grade A. The arrangement in which the MBR preceded NF was also found to limit the amount of soil and solids entering subsequent treatment, which therefore improved the efficiency of NF, as demonstrated by the stability of post-NF transmembrane pressures throughout three cycles renewed by two backwashes.

“…Pharmaceuticals and personal care products (PCPs) comprise numerous chemical classes. Pharmaceuticals and PCPs contain a large and diverse group of organic compounds, including endocrine disrupting compounds and pharmaceutically active compounds [34] with a significant impact on water ecology and human health [35]. Current wastewater treatment procedures have the capacity to eliminate only partially Pharmaceuticals and PCPs and, therefore, they will be found in receiving waters or in the resulting sludge which is sometimes used as fertilizer [36].…”

Wastewater Reflections in Consumer Mind: Evidence from Sewage Services Consumer Behaviour

et al. 2018

Environmental concerns have become an important decision-making determinant for consumers. Hundreds of emerging pollutants and their metabolites are listed as present in European aquatic environments and human settlements are blamed as major sources of water pollution. It was assumed that as long as water treatment is not totally effective and it requires a high amount of energy and resources, household’s contribution through correct behaviour in relation to the load of waste they discharge in the sewage system can reduce efforts towards wastewater treatment. Consequently, the main objective of this study was to investigate households’ perception and behaviour related to wastewater treatment services. Results are based on a random survey with a sample of 125 Romanian consumers of water supply and sewage services. A key finding is that investigated wastewater services consumers perceive the effect of discharging untreated wastewater in the environment as highly negative both on human health and on the environment, thus pointing out the importance associated by them to water treatment. This research argues that understanding wastewater services consumer behaviour enlarges the way toward reducing environmental disturbances.

“…The results suggested that the integrated membrane systems can achieve even higher removal rates of above 95% for most of them. Further studies showed that MBR-RO achieved even better results with the removal of 20 compounds to below detection limits as compared to 13 compounds by MBR/NF [72]. A study conducted by Baransi-Karkaby et al reported the improved rejection of multiple EDCs and pharmaceutically active compounds (PhACs) by RO membrane elements using concentration polarization-and surfactant-enhanced surface polymerization [73].…”

This review covers various methods to remove, treat, and detect emerging contaminants (ECs) in water and wastewater. ECs have drawn the attention of many countries due to their potential threat to human health as well as the environment. They are found in many human everyday products that are continuously released into the environment and will accumulate over time. In order to remove ECs, a number of methods have been developed, which include adsorption, membrane technology, biological treatment, and advanced oxidation process. In addition, advances in detection techniques and instrumentation are now able to detect ECs in which they occur at low concentrations. All the removal, treatment, and detection methods will be covered in this review. The removal, treatment, and detection of ECs and their transformation products in water and wastewater are challenging tasks due to their complexity in water samples. Therefore, such information should be emphasized in order to improve the current methods and develop new advanced methods.
