  • Perspectives on modelling micropollutants in wastewater treatment plants

    Models for predicting the fate of micropollutants (MPs) in wastewater treatment plants (WWTPs) have been developed to provide engineers and decision-makers with tools that they can use to improve their understanding of, and evaluate how to optimize, the removal of MPs and determine their impact on the receiving waters. This paper provides an overview of such models, and discusses the impact of ...

  • Monitoring the variations of the oxygen transfer rate in a full scale membrane bioreactor using daily mass balances

    Oxygen transfer in biological wastewater treatment processes with high sludge concentration, such as membrane bioreactor (MBR), is an important issue. The variation of α-factor versus mixed liquor suspended solids (MLSS) concentration was investigated in a full scale MBR plant under process conditions, using mass balances. Exhaustive data from the Supervisory Control And Data Acquisition (SCADA) ...

  • OSU Researchers Deploy Stevens Equipment in Study of Green Infrastructure Treatment for Groundwater Runoff

    Stormwater runoff pollution is a serious issue that faces almost every urban and suburban environment. In older city infrastructure, runoff from roofs, parking lots, and streets flows directly into the sewer system and must be handled by the municipal wastewater treatment facility, increasing the amount of work the system must undertake. For the past 30 years, the infrastructure for stormwater ...

  • Developing a typical rainfall period to analyze CSOs in San Francisco

    The City of San Francisco has used InfoWorks CS as the basis for developing a continuous long-term (five year) rainfall period, which is being used to evaluate sewer flows in a collection system model. Ultimately, the City aims to develop a 30-year plan for its combined sewer and wastewater treatment system, a major cornerstone of which is the creation and application of a detailed hydraulic ...
