Wastewater Treatment Plant Effluent

Experiments with the ultraviolet (UV)/H2O2 advanced oxidation process (AOP) were conducted to investigate the abatement of micropollutants in wastewater treatment plant effluent. The fluence and the starting concentration of H2O2 in a bench-scale batch reactor were varied according to response surface method (RSM) to examine their influence on the treatment efficiency. It was shown that the investigated AOP is very effective for the abatement of micropollutants with conversion rates typically higher than 90%. Empirical relationships between fluence, H2O2 dosage and the resulting concentration of micropollutants were established by RSM. By this means it was shown that X-ray-contrast media had been degraded only by UV light. Nevertheless, most substances were degraded by the combination of UV irradiation and H2O2. Based on RSM an optimisation of multiple responses was conducted to find the minimal fluence and H2O2 dosage that are needed to reach an efficient abatement of micropollutants.

Wastewater Treatment Plant Effluent

Wastewater treatment plant effluents contain a variety of endocrine disrupting chemicals (EDCs), including chemicals with estrogenic activity such as 17β-estradiol (E2), 17α-ethinyl estradiol (EE2), and nonylphenols. These substances can affect both behavior and physiology in vertebrate animals. To explore the presence and effects of these EDCs in a natural setting, juvenile and adult male fathead minnows, Pimephales promelas, were held in cages upstream and downstream of the effluent site of a wastewater treatment plant for 21 days and subsequently tested for changes in reproductive behaviors and production of vitellogenin. Additionally, estrogenic activity in the stream was measured using a yeast bioassay. Estrogenicity was found to be significantly higher downstream of the wastewater effluent when compared to levels upstream. Vitellogenin levels did not show a correlational pattern with levels of estrogenicity in the water, but two measures of reproductive behaviors occurred significantly less often in downstream males than upstream males. This suggests that a brief (three-week) exposure to stream water containing wastewater treatment plant effluent can bring about changes in reproductive behavior of fish and that behavior may be more sensitive to low levels of environmental endocrine disruptors than vitellogenin production.
