Rolling literature review on pathogen reduction by water treatment processes
Dr. Patrick Smeets | KWR Watercycle Research Institute | Netherlands
In order to assess safety of water reuse, knowledge about the effect of water treatment on pathogenic microorganisms is crucial. However, scientific knowledge is spread out over various journal publications and grey literature. KWR, KWB and University of Colorado are joining forces in a rolling literature revision, extracting quantitative data on treatment performance. The data will be accessable through an interactive webtool, which wil be connected to a tool for Quantitative Microbial Risk Assessment (QMRA). At the conference we want to bring this development to the attention of end-users (water reuse industry) and initiate new collaborations for continuation of the work in the future.
Application of a model for supporting risk assessment of emerging contaminants in the context of wastewater reuse for irrigation
Dr. Riccardo Delli Compagni | Politecnico di Milano | Italy
Irrigated fields with reclaimed wastewater may result in accumulating emerging contaminants (ECs) in crops, leading to human exposure through the food chain. A model for supporting risk assessment of EC fate in wastewater treatment and irrigated crops was developed and tested for an Italian catchment. A risk assessment was performed for various ECs and potential harmful situations were identified.
Virus Detection Methods for Water Reuse Applications
Junior professor Krista Wigginton | University of Michigan | United States
This presentation covers recent advances in virus detection methods that are relevant for water reuse. Specifically, we will review the most successful approaches for concentrating viruses from large volumes of water and discuss recent advances in virus detection methods, including culture-based methods, PCR-based methods, viral metagenomics, and flow virometry.
Flow Cytometric Monitoring of a German Pilot Study for Treating Municipal Wastewater to Different Water Quality Standards
Dr. Andreas Nocker | IWW Water Centre | Germany
A German research consortium assessed the suitability of a combination of different water treatment technologies to treat municipal wastewater treatment plant effluent to different quality levels. Flow cytometry was used in combination with traditional microbiological monitoring to assess changes in the microbiology and in the regrowth potential along the treatment train.
Quantitative exposure and risk assessments of sequential biofiltration within a potable reuse treatment train
Dr.-Ing. Veronika Zhiteneva | Technical University of Munich | Germany
In order to perform a chemical risk assessment for two water reuse systems utilizing the sequential biofiltration approach and oxidation via air or ozone, a Bayesian network was created, which uses probability distribution functions to characterize nodes describing the states of contaminant and bulk water quality parameter concentrations to predict final effluent concentrations.
Reduction of viruses using a semi-industrial and near-natural system for advanced wastewater treatment
Christian Rien | German Enviroment Agency | Germany
As part of the BMBF project „TrinkWave“, the German Environment Agency is involved in the design of a semi-industrial and near-natural system (SMART Plus) intended for advanced wastewater treatment. We studied the potential of SMART Plus to eliminate viruses. Results showed, that spiked phages were reduced by about 4 to 5 log units in the SMART Plus.
