Abstract: (25 Views)
Introduction: Pharmaceutical materials and antibiotics are a part of emerging pollutants in aqueous environments, which threaten human and environmental health at low environmental concentrations. Amoxicillin is a most-used antibiotic in the treatment of infections most of which is disposed as non- metabolized, then enters into wastewater and finally come into the environment.
Materials & Methods: Present study was conducted with the aim of investigating the process of cyclic activated sludge with moving bed in removing amoxicillin from aqueous environments. Following preparing amoxicillin and other chemical compounds in this experimental study, first required reactor at pilot scale with volume of about 100 L was designed, prepared, equipped and sealed. Then prepared system was transferred to urban wastewater treatment plant and installed there.
Results: Regarding low value of antibiotic in urban wastewater, after initial setting up, fixing possible defects and stability of reactor, amoxicillin was fed into the inlet wastewater by adding concentrations of 5, 10, 15 and 20 mg/L and then sampling, preparation, samples filtration and making required trials were done and subsequently concentration of amoxicillin was obtained through HPLC system. In order to analyze statistical data in Excel software, efficiency of the reactor of cyclic activated sludge with moving bed in removing amoxicillin from wastewater was evaluated. Based on the obtained results and the best operating conditions of the system, the highest rate of removing amoxicillin pollutant with inlet concentration of 5mg/L and 12 hours Hydraulic retention time of 94.3% were achieved.
Conclusion: Regarding suitable conditions of model in removing pharmaceutical pollutants and other organic materials, applying this method in designing and exploiting MBAS system was suggested.
