An innovative approach for modeling aerobic granular sludge processes. Proceedings WEFTEC.17
Abstract: An innovative biofilm model has been developed that allows modeling of a granular sludge sequencing batch reactor (GSBR) in a single tank without the need for a separate variable volume tank and a recycle stream. The model has a variable volume, supports separate or simultaneous feeding and effluent discharge, predicts the biofilm thickness without being constrained by a maximum ...

The fate and behaviour of organic micropollutants during wastewater treatment processes: a review
The fate and behaviour of selected insecticides, herbicides, and polychlorinated biphenyls during primary sedimentation and secondary biological treatment of waste water are evaluated. The physico-chemical properties (chemical structure, aqueous solubility, octanol/water partition coefficient and Henry's Law constant) of these compounds which dictate the extent and mechanism of their removal ...

Sustainable wastewater treatment chemicals in a chicken processing plant
Atana Ltd was invited to evaluate the potential for introducing an organic, sustainable wastewater treatment regime into a chicken processing plant. The flow was approximately 120m³ (over 18 hours per day). The plant killed around 126000 birds per day and the sludge volume produced from their effluent treatment plant (which encompassed dissolved air flotation) per annum was around 13000 ...

Urban wastewater effluent increases antibiotic resistance gene concentrations in a receiving northern european river
Antibiotic resistant bacteria are an emerging global problem which threatens to undermine important advances in modern medicine. The environment is likely to play an important role in dissemination of antibiotic resistance genes (ARGs) among both environmental and pathogenic bacteria. Wastewater treatment plants (WWTPs) accumulate both chemical and biological waste from the surrounding urban ...

Improving biological phosphorus removal in membrane bioreactors – a pilot study
With increasing water reuse applications and possible stringent regulations of phosphorus content in secondary and tertiary effluent discharge in Florida, USA, alternative technologies beyond conventional treatment processes require implementation to achieve low phosphorus (P) and nitrogen (N) concentrations. A pilot scale membrane bioreactor (MBR) system, operated in Florida, adopted the ...

Community-based wastewater treatment systems and water quality of an Indonesian village
This paper examines the impact of community-based water treatment systems on water quality in a peri-urban village in Yogyakarta, Indonesia. Water samples were taken from the wastewater treatment plants (WWTPs), irrigation canals, paddy fields and wells during the dry and wet seasons. The samples were tested for biological and chemical oxygen demand, nutrients (ammonia, nitrate, total nitrogen ...
