Many industries generate phenolic wastewater of acidic nature. Neutralization with sodium hydroxide generates the phenolic wastewater with high TDS. Both phenol and ionic concentration of TDS are inhibitor to biological treatment processes. A study was carried out for biological treatment of phenolic wastewater with high total dissolved solid (TDS) concentration in moving bed biofilm reactor (M...

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 p...

Degradation of Iodinated X-Ray Contrast Media by Ozone and Ozone/H2O2 High solubility in water Low vapour pressure Low distribution coefficient, log kow = 2.33 Low potential for adsorption Low potential for bioaccumulation Chemical and biological stability Option 1. • Removal by conventional municipal wastewater treatment “There is no significant removal of x-ray contrast media by conventional ...

This work demonstrates the usefulness of non-linear data reconciliation to evaluate available measurements and estimate unmeasured variables for a full-scale partial nitritation (SHARON) reactor for the treatment of wastewater with high ammonium concentrations. Despite a lack of measured data, the bilinear approach of formulating system constraints allowed to satisfy the requirements for data r...

Full-scale wastewater treatment facilities are not able to prevent microplastics (MPs) from discharging into natural waters and they also associated with the land application of sludge. This study evaluates distribution microfibers (MFs) in a lab-scale sequencing batch reactor (SBR) fed by synthetic (SW) for 93 days. The MFs were analyzed through optical microscopy mixed liquor (ML) effluent, s...
