background: a new biological domestic wastewater treatment process, which has been presented these days in activated sludge modification, is upflow sludge blanket filtration (usbf). this process is aerobic and acts by using a sludge blanket in the separator of sedimentation tank. all biological flocs and suspended solids, which are presented in the aeration basin, pas through this blanket. the ...

Introduction: Macrolides are a group of antibacterial agents. Given their clinical importance, and the consistent rise in resistance among pathogenic bacteria, macrolides have been the targets of extensive research. Materials and Methods: This review considered the number of macrolides in different wastewater and the removal of these drugs. The antibiotics were frequently detected in influents...

Li Si, Kong Ruixue, Sun Lin, Li Sifan, Yang Shuangchun* (Liaoning Shihua University. Fushun, Liaoning, China. 113001) Abstract—Industrial wastewater is a kind of wastewater that generate in the industrial production process. The wastewater from refining and coal carbonization contains high concentration of phenols pollutants. In this paper, study on phenol treatment methods in industrial wastew...

We investigated the conventional characterisation and biological treatability of wastewaters of the “Izmit Industrial and Domestic Wastewater Treatment Plant”. Respirometric procedures were carried out for the experimental assessment of organic contents of wastewater. The mean value of total COD was 1201 mg·l-1 and varied within a wide range of 580 to 1822 mg·l-1 for the 14 different influents....

Waste management studies are usually done using calibrated and verified water quality models. Ravi River located in Lahore, Pakistan is receiving untreated wastewater from number of outfalls and surface drains and thus model calibration and verification are done using the data under the prevailing conditions. The water quality objectives can only be met with wastewater treatment wherein the mod...

Combined treatment of landfill leachate and municipal wastewater was performed in order to investigate the changes of leachate toxicity during biological treatment. Three laboratory A2O lab-scale reactors were operating under the same parameters (Q-8.5-10 L/d; HRT-1.4-1.6 d; MLSS 1.6-2.5 g/L) except for the influent characteristic and load. The influent of reactor I consisted of municipal waste...
