“…In contrast, RO is a phase-changing process that does not degrade or destroy contaminants but rather concentrates them into a stream of waste or "reject" material that must then be dealt with (Joo and Tansel 2015;De la Cruz et al 2012;Rodriguez-Mozaz et al 2015;Romeyn et al 2016). The application of both RO and ozonation has been demonstrated for treatment of PhACs in drinking water (Albergamo et al 2019;Gomes et al 2017) and wastewater (Paucar et al 2019) in few pilot-scale studies. However, a comparison of the efficacy of these two technologies to treat PhACs in wastewater has yet to be reported.…”

Pharmaceutically active compounds (PhACs) reaching surface waters through municipal wastewater are a concern, as existing treatment processes poorly remove them. While significant lab-scale evaluations have been performed on treatment options, full-scale tests are lacking. Presented is an experimental study from a full-scale research facility that is imbedded in a functioning municipal wastewater plant. Reverse osmosis and ozonation were tested as part of an active treatment train using secondary treated effluent from the adjoining facility. Reverse osmosis removed 92.6%, 99.0%, 99.6%, 97.8%, 99.0%, 99.6%, 99.9%, and 99.2% of metformin, cotinine, trimethoprim, caffeine, venlafaxine, carbamazepine, erythromycin, and fluoxetine, respectively. By ozone, sulfamethoxazole, carbamazepine, erythromycin and o-desmethylvenlafaxine were removed by more than 99.9%. Trimethoprim and venlafaxine were removed by more than 95%, with the remaining compounds removed by between 16% and 85%. Results demonstrate the effectiveness of reverse osmosis and ozonation for full-scale treatment.

“…The ozone dose applied was found to affect the removal efficiency of some PPCPs. Apart from ozone dose, the reaction time was also found to be one of the main factors to remove ECs, as can be seen in the study conducted by Paucar et al to remove 38 PPCPs [97]. Among the 38 PPCPs detected in the secondary effluent, 31 PPCPs were degraded to or below their LOD at the ozone dosage of 6 mg/L in 10 min.…”

Emerging Contaminants

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.

“…These facts have aroused great interest in investigating wastewater treatment techniques that remove or degrade PPCPs, including filtration [10,11], adsorption [12,13], coagulation/flocculation [14], biological processes [15,16], and degradation by various advanced oxidation processes (AOPs) such as photo-Fenton [17,18], ozonation [19,20], ultrasound treatment [21], electrochemical oxidation [22,23], ultraviolet (UV)/H 2 O 2 [24,25], etc. Among the AOPs, degradation using ultraviolet-visible (UV-Vis) irradiation and nanomaterials as photocatalytic agents must be highlighted due to the promising results obtained up to now [26][27][28][29][30][31].…”

Nanomaterial Synthesis in Ionic Liquids and Their Use on the Photocatalytic Degradation of Emerging Pollutants

et al. 2021

The unique properties of ionic liquids make them suitable candidates to prepare nanoscale materials. A simple method that uses exclusively a corresponding bulk material and an ionic liquid—in this case, [P6,6,6,14]Cl—was used to prepare AgCl nanoparticles and AgCl@Fe3O4 or TiO2@Fe3O4 magnetic nanocomposites. The prepared nanomaterials were characterized by X-ray powder diffraction, scanning electron microscopy, transmission electron microscopy, ultraviolet–visible spectroscopy, and X-ray photoelectron spectroscopy. The photodegradation of atenolol as a model pharmaceutical pollutant in wastewater was investigated under ultraviolet–visible light irradiation using the different synthesized nanocatalysts. In the presence of 0.75 g·L−1 AgCl nanoparticles, a practically complete degradation of 10 ppm of atenolol was obtained after 30 min, following pseudo-first-order reaction kinetics. The effect of different variables (concentrations, pH, oxidant agents, etc.) was analyzed. The recyclability of the nanocatalyst was tested and found to be successful. A degradation mechanism was also proposed. In order to improve the recovery stage of the nanocatalyst, the use of magnetic nanocomposites is proposed. Under the same experimental conditions, a slightly lower and slower degradation was achieved with an easier separation. The main conclusions of the paper are the suitability of the use of ionic liquids to prepare different nanocatalysts and the effectiveness of these at degrading an emerging pollutant in wastewater treatment.
