Removal of Residual Pharmaceuticals in a Secondary Effluent from a Sewage Treatment Plant by Ozonation

Pharmaceuticals in Wastewater Treatment Plant Effluent Waters

Pharmaceuticals are being used at an increasing rate, and end up in wastewater through excretion and disposal. They also end up in the effluent water of wastewater treatment plants because they are not specifically designed for pharmaceutical removal. Several studies suggest diverse negative effects on aquatic life that are exposed to these trace amounts of pharmaceuticals in their habitats. Th...

Real-time control of micropollutant removal from secondary effluent by ozonation

Ozonation has shown to be a promising technology in removing micropollutants from wastewater effluent but current basic control strategies still result in sub-optimal ozone dosing. This work aimed at applying novel, yet simple, surrogate models (based on delta UVA254), to assess the micropollutant removal on pilot-scale as a proof-of-concept. Different events and fluctuations in effluent condit...

advanced treatment of sahebgharanieh secondary effluent by ozonation

chemical oxidation is one of the most suitable treatment methods for reducing organic pollutants and the number of pathogens remaining in secondary effluents. ozone is the most powerful oxidizing agent commonly used because of it's many advantages over chlorination. in this study the efficiency of ozonation in advanced wastewater treatment of sahebgharanieh plant has been determined. ozone gene...

Removal of pharmaceuticals from a WWTP secondary effluent by ultrafiltration/reverse osmosis followed by electrochemical oxidation of the RO concentrate

Poliovirus removal from primary and secondary sewage effluent by soil filtration.

Adsorption of poliovirus from primary sewage effluent was similar to that from secondary sewage effluent in both batch soil studies and experiments with soil columns 240 cm long. Virus desorption by distilled water was also similar in a soil column that had been flooded with either primary or secondary effluent seeded with virus. These results indicated that absorption of poliovirus from primar...
