“…In addition, solar photocatalysis has an excellent result of emerging pollutants removal. Bernabeu et al (2011) found the concentrations of emerging pollutants were under the detection limit after solar photocatalysis with TiO 2 . The removal of pharmaceuticals and personal care products was more than 90%, and the concentration was less than 10 ng/L after the treatment of biological activated carbon filter (Reungoat et al, 2011).…”

The growing water stress both in terms of water scarcity and quality deterioration promotes the development of reclaimed water as a new water resource use. This paper reviewed wastewater reuse practices in China, and the opportunities and challenges of expanding reclaimed water use were analyzed. Rapid urbanization with the increasing of water demand and wastewater discharge provides an opportunity for wastewater reuse. The vast amount of wastewater discharge and low reclaimed water production mean that wastewater reuse still has a great potential in China. Many environmental and economic benefits and successful reclamation technologies also provide opportunities for wastewater reuse. In addition, the overall strategy in China is also encouraging for wastewater reuse. In the beginning stage of wastewater reclamation and reuse, there are many significant challenges to expand wastewater reuse in China including slow pace in adopting urban wastewater reuse programs, the establishment of integrated water resources management framework and guidelines for wastewater reuse programs, incoherent water quality requirements, the limited commercial development of reclaimed water and the strengthening of public awareness and cooperation among stakeholders.

“…It is well established that conventional water and wastewater treatment processes are not adequate for the effective removal of many trace organic contaminants (Ternes et al, 2004). The need for a more robust treatment process has triggered many dedicated scientific investigations to develop new methods to obtain high quality treated effluent from domestic wastewater, particularly with a focus on the removal trace organic contaminants (Cartinella et al, 2006;Shannon et al, 2008;Alturki et al, 2010;Cath et al, 2010;Bernabeu et al, 2011;Li et al, 2011;Patterson et al, 2011).…”

Following the initial gradual decline, a stable permeate flux value was obtained after approximately four days of continuous operation. There was evidence of continuous deterioration of biological activity of the OMBR system, possibly due to the build-up of salinity in the reactor. The removal of 25 out of 27 trace organic compounds with molecular weight higher than 266 g/mol was above 80% and was possibly governed by the interplay between physical separation of the FO membrane and biodegradation. In contrast, the removal efficiency values of the other 23 trace organic compounds with molecular weight less than 266 g/mol were very scattered. The removal efficiency of these low molecular weight compounds by OMBR treatment appears to depend mostly on biological degradation. Crown

“…The validation of the model in such wide intervals of catalyst and irradiation conditions is important for the automatisation of the process. The three model pollutants have been found in wastewater treatment plant effluents with concentrations between 50-100 ng l -1 (Bernabeu et al, 2011;Ortelli et al, 2005). Nevertheless, a concentration of 100 μg l -1 was used, which was low enough to be considered a micropollutant mixture, but high enough to monitor through UPLC.…”

This paper is focused on modelling the degradation of micropollutants by solar photo-Fenton at pilot plan scale. To this aim, a three pesticide mixture (acetamiprid, thiabendazole and imazalil, 100 μg l ). A Monte Carlo direct search was used to determine the kinetic constants which adjusted pesticide removal and hydrogen peroxide consumption in the selected experimental conditions (identification runs). The model was validated with experimental conditions different from the identification step (validation runs). Hydrogen peroxide consumption and pollutant degradation could be predicted adequately for all irradiances and iron concentrations higher than 5 mg l -1 Fe. As a result, the presented model could predict the treatment time during the whole year, as it is valid for a wide range of irradiation and for commonly used values of catalyst concentration.
