Removal characteristics of retinoic acids and 4-oxo-retinoic acids in wastewater by activated sludge treatment
Retinoic acid (RA) receptor (RAR) agonists are potential teratogens to various vertebrates. Their contamination has been detected in municipal wastewater in different countries. This study involved field investigations and laboratory batch treatment experiments to elucidate the removal characteristics by activated sludge treatment of RAs (all-trans RA and 13-cis RA) and 4-oxo-RAs ...

Biodegradation of bisphenol A, 17 β-estradiol, and 17 α-ethynylestradiol in river water
The degradation of bisphenol A (BPA), 17 β-estradiol (E2), and 17 α-ethynylestradiol (EE2) in river water was investigated. Moreover, the effects of temperature, nutrient salts, easily degraded coexisting organic matter, and the addition of municipal wastewater, were studied. The half-lives of E2 are six days at 20°C and three days at 30°C in river water, respectively. BPA is degraded ...

Pyrethroid insecticides in municipal wastewater
Pyrethroids are widely used insecticides, but there is minimal published information on their presence in municipal wastewater in the United States. Pyrethroids in wastewater from the Sacramento, California area, consisted of permethrin, bifenthrin, cypermethrin, and cyhalothrin with a combined concentration of 200–500 ng/L. Sampling within the wastewater collection system leading to the ...

Combination of ion exchange and partial nitritation/Anammox process for ammonium removal from mainstream municipal wastewater
In this study, a new technology of nitrogen removal from mainstream municipal wastewater is proposed. It is based on ammonium removal by ion exchange and regeneration of ion exchange material with 10–30 g/L NaCl solution with further nitrogen removal from spent regenerant by partial nitritation/Anammox process. Influence of regenerant strength on performance of ion exchange and ...

A nine-point pH titration method to determine low-concentration VFA in municipal wastewater
Characterization of volatile fatty acid (VFA) in wastewater is significant for understanding the wastewater nature and the wastewater treatment process optimization based on the usage of Activated Sludge Models (ASMs). In this study, a nine-point pH titration method was developed for the determination of low-concentration VFA in municipal wastewater. The method was evaluated using synthetic ...

Stability of alumina, ceria, and silica nanoparticles in municipal wastewater
Inorganic oxide nanoparticles (NPs) are used in semiconductor manufacturing operations such as wafer chemical–mechanical planarization (CMP). Understanding the stability of NPs in municipal wastewater is essential for the evaluation of the fate of NPs released to municipal wastewater treatment plants (WWTPs). This study aimed to evaluate the stability of Al2O3, CeO2, and SiO2 NPs and CMP ...

The MIEX® Technology for Municipal Wastewater Treatment
The MIEX® Technology is designed for the removal of dissolved organic carbon (DOC). Until recently, the commercial application of the MIEX® Technology has been limited the treatment of potable water from surface or ground water bodies. The MIEX® Process is now being evaluated for application in municipal wastewater applications. An example of this is the use of the MIEX® Process for the ...

Bioaugmentation as a tool to accelerate the start-up of anoxic-oxic process in a full-scale municipal wastewater treatment plant at low temperature
Start up of anoxic-oxic process in a full-scale municipal wastewater treatment plant at low temperature was studied in this paper. Bioaugmentation technology was used to accelerate the start up. Aeration rate and feed style of influent were also controlled as associated measure to reduce the negative effect of low temperature on start up. The results showed that the process was successfully ...

MBR Operation
Although membrane bioreactor (MBR) technology has grown up to become a state-of-the-art in municipal wastewater treatment during the last decade, design, construction and operation of MBRs has not yet become a routine function. An insight into the practice of MBR technology will be available as a report at IWA Publishing by October 2010. ‘Operating Large-Scale Membrane ...
