Continuous-flow sludge settling: a mechanistic 2 × 2 dynamic model, numerical validation and predictions for decision making Open
The separation of solid particles from the liquid phase is the final operation in an activated sludge wastewater treatment plant. This paper introduces a one-dimensional, knowledge-based dynamic model incorporating both mass and momentum b…

Upgrading wastewater treatment plants to urban mines: Are metals worth it? Open
After usage, extracted metals end up back to the environment but dispersed at much lower concentrations. Wastewater treatment plants (WWTP) are one of the last sites where metals go through before discharge into the environment. This artic…

Treatment of micropollutants in wastewater: Balancing effectiveness, costs and implications Open
In this contribution, we analyse scenarios of advanced wastewater treatment for the removal of micropollutants. By this we refer to current mainstream, broad spectrum processes including ozonation and sorption onto activated carbon. We arg…

What is the fate of trace metals and phosphorus in CW receiving treated wastewater? Contributions of free water, plants and soil Open
Constructed Wetlands receiving Treated Wastewater (CWtw) are systems downstream of Wastewater Treatment Plants (WWTPs) before the receiving water bodies. They have recently become attractive in France under the perception that they improve…

Fate of phosphorus in two constructed wetlands receiving treated wastewater:contributions of free water, soil and plants retention Open
Constructed Wetlands receiving treated wastewater (CWtw) have recently become attractive in France under the perception that they would increase water quality of the WWTP effluent. This study focuses on the fate of phosphorus (P) in 2 pilo…

Removal efficiencies and kinetic rate constants of xenobiotics by ozonation in tertiary treatment Open
This study gives a full overview of the chemical oxidation by ozone of selected xenobiotics usually present in effluents of conventional wastewater treatment plants. A qualitative and quantitative overview of literature data was made, and …

Photodégradation de micropolluants organiques sous rayonnement solaire en zone de rejet végétalisée de type bassin. Rapport final Open
Wastewater treatment plants usually remove a significant amount of micropollutants by volatilization, sorption and/or biodegradation. Nevertheless, secondary effluents still contain various pharmaceutical compounds and pesticides at very l…

Projet BIOTRYTIS : Description du site expérimental, des équipements et de la métrologie. Rapport final Irstea-Onema Open
Buffer zones between wastewater treatment plants and receiving water bodies have recently gained interest in France. These planted discharge areas (PDA) receive treated wastewater and may have various designs aiming to mimic 'natural' wetl…

Suspected-target screening strategy to investigate degradation by ozonation or photolysis of urban micropollutants in waste waters Open
Conventional wastewater treatment plants (WWTPs) partially eliminate micropollutants present in domestic and industrial discharges (Martin-Ruel et al., 2010; Choubert et al., 2011). However, some molecules still occur in effluents of WWTPs…
