Approximately 3,500 constructed wetlands (CWs) provide raw wastewater treatment in France for small communities (<5,000 people equivalent). Built during the past 30 years, most consist of two vertical flow (VFCWs) series (stages). Many configurations exist, with systems associated horizontal filters or waste stabilization ponds, recirculation, partially saturated systems, etc. A database analyzed 10 years earlier on classical French system summarized global performances data. This...
Seven treatment wetlands and a municipal wastewater plant (WWTP) were weekly monitored over the course of one year for removal conventional parameters, selected micropollutants (caffeine, ibuprofen, naproxen, benzotriazole, diclofenac, acesulfame, carbamazepine) biological effects. The wetland designs investigated include horizontal subsurface flow (HF) variety with intensification (aeration, two-stages, or reciprocating flow). Complementary to common approach analyzing individual chemicals,...
The use of electrical resistivity tomography in laboratory or field experiments for environmental purposes has been increasing recent years. development commercial devices thus far focused on the quality measurements and their robustness all cases. However, both costs lack flexibility to adapt specific applications have limited prevalence sector. This article presents a low-cost, open hardware meter provide scientific community with robust flexible tool small-scale experiments. Called OhmPi,...
French vertical flow constructed wetlands (VFCW) treating raw wastewater have been developed successfully over the last 30 years. Nevertheless, two-stage VFCWs require a total filtration area of 2–2.5 m2/P.E. Therefore, implementing one-stage system in which treatment performances reach standard requirements is interest. Biho-Filter® one solutions France by Epur Nature. with an unsaturated layer at top and saturated bottom. The aim this study was to assess new configuration optimize its...
ABSTRACT Treatment wetlands (TWs) effectively remove target pollutants and enhance urban water circularity resilience. They constitute a prominent solution for wastewater treatment, thanks to their adaptability across various types of wastewater, scales climatic conditions. However, the disparity in TW designs focus on restricted set variables applicable research studies impede any comprehensive evaluation comparison performance. Our study introduces methodology data validation, concurrently...
ABSTRACT To improve risk assessment, control and treatment strategies of contaminated sites, we require accurate methods for monitoring solute transport infiltration in the unsaturated zone. Highly spatio‐temporal heterogeneous during snowmelt increases contaminating groundwater areas where de‐icing chemicals are required winter maintenance roads runways. The objective this study is to quantify how different processes occurring meltwater affect bulk electrical resistivity. Field experiments...
Lifespan and well-operation of French vertical flow constructed wetlands (VFCW) depend on how the organic deposit forms evolves within filter media. This study aimed to demonstrate feasibility thin section methods application VFCW. Unfortunately, wetland scientists are currently missing tools observe physically occupies pore space. Thin sections allow a direct undisturbed observation media deposit. Undisturbed samples were taken from surface an experimental Water was exchanged with solvent...
Scientists and practitioners exhibit an increasing interest on effluent transfer degradation modelling in Vertical Flow Sand Filters (VFSF) Constructed Wetland (VFCW). Modelling software used to this purpose is mainly monophasic: the unsaturated zone, only water flow taken into account air phase influence assumed be negligible. In hydrology, many studies have point out limitations of assumption order quantify movement but little has been done vertical filter. Despite its complexity,...
Over the last 10 years soil-based constructed wetlands for discharge of treated wastewater (TWW) are commonly presented as a valuable option to provide tertiary treatment. The uncomplete knowledge in soil modifications and lack clear design practices laid foundation this work. aim study was determine optimal hydraulic loads observe main critical parameters affecting treating performances acceptance. For purpose, rich clay backfill chosen perform column infiltration tests with TWW. Two...
