Engineering and modeling aspects of water detoxification systems for the removal of estrogens, antibiotics, and other contaminants of emerging concern
Photo-assisted water detoxification with solar or with artificial sources of radiation is a feasible and potentially low-cost method for the removal of micropollutants and emerging contaminants (ECs) from water resources.These include sub-ppm levels of cyano-toxins,estrogens,pharmaceuticals,personal care products,pesticides and many other ECs.Here we review potential treatment methods and highlight the importance of rational reactor design for the effective degradation of ECs.In one example,using actual wastewater effluent.from a municipal waste water treatment plant in Spain,we show that the removal of 52 emerging contaminants by TiO2-photocatalysis in pilot-scale reactors can be accomplished more effectively in compound parabolic collector (CPC) reactors With tube diameters larger than standard and using very low concentrations of the TiO2 catalyst.The design criteria of such reactors are based on the principles of photon transport and radiation absorption and are strongly dependent on the optical properties of the photocatalysts.These engineering and modelling aspects will be presented and applied to pilot-scale water detoxification for the removal of estrogens (estrone,17β-estradiol,17α-ethynylestradiol and estriol),pesticides (tfiazines,phenylurea) and other ECs.
