Antibiotics have been considered emerging pollutants due to their continuous input and persistence in the aquatic ecosystem. The present paper addresses the degradation and removal processes applied to a specific class of micropollutants, the antibiotic tetracycline (TETRA). Photocatalytic degradation of tetracycline in aqueous suspensions of titanium dioxide in the presence of titanium dioxide (TiO2) and ultraviolet (UV) illumination was performed in a vertical circulating photocatalytic reactor. The optimum catalyst concentration was about 0.1g/L.

This study was conducted to investigate the characteristics of inflow and outflow wastewater of the Bandargaz wastewater treatment plant on the basis of the data collection of operation period and the samples taken during the study. Also the effects of mid-term use of the wastewater for irrigation (from 2005 to 2013) on soil physical and chemical characteristics were studied. For this purpose, 4 samples were taken from the inflow and outflow wastewater and 25 quality parameters were measured.

The emerging field of sewage chemical-information mining is taking advantage of a readily available yet underappreciated resource: the untreated waste flowing under our feet and the biosolids remaining after treatment. It turns out that sewage and sewage sludge hold a wealth of data on chemical consumption and exposure, and potentially even the health status of whole communities.
