Résumé :

The depth of constructed wetlands (CWs) significantly affects the construction investment that influences the efficiency of the CW and is an important design consideration for optimal performance. The aim of the study was to examine the influence of depth on nitrogen retention in 12 pilot scale free surface water CWs in Plönninge (56◦43 45 N, 12◦43 33 E): 6 shallow wetlands with a maximum depth of 0.5 m and 6 deeper wetlands with a maximum depth of 0.8 m. The outlet N concentration in shallow and deep wetlands were found to be significantly different (p<0.05, p= 0.017). Outlet N concentrati

Background: Wetlands store significant amounts of carbon through plant respiration and anaerobic peat formation, however, there is little knowledge on which factors affect the carbon storage distribution within wetlands. Aims: To determine how much carbon and nitrogen wetlands can store over time and whether there are patterns of high and low carbon and nitrogen storage within wetlands. Methods: Peat samples of a defined volume, cut out from three constructed wetlands were dried, weighed and analysed for their carbon and nitrogen content.

Résumé :

This study investigates the effect of ecosystem age on the nitrate removal efficiency, nitrate removal rate and first-order area-based removal rate coefficients (both with and without temperature adjustment) of created wetlands. Data was collected from the first to eleventh year after wetland creation in an experimental wetland facility in south-west Sweden. The 18 small (22-29 m2) free water surface wetlands were divided into three groups based on initial planting: EVW (emergent vegetation wetlands), SVW (submerged vegetation wetlands) and CW (unplanted control wetlands).

Résumé :

The population size of the horned grebe, Podiceps auritus, is declining in most of the world due to loss of wetlands, deteriorating water quality and establishment of predatory fish such as pike, Esox lucius, in former fish free wetlands. The horned grebe is now globally classified as vulnerable. In this study, data on population dynamics of the horned grebe in six created wetlands in Linköpings kommun was examined together with field work carried out in three of the wetlands. The results indicate that the number of pairs and juveniles of horned grebe crash six to eight years after the wetlan

Résumé :

The climate changes, the natural resources depletion, the population number increase are alarm bells for the future that must push the humanity to turn on more sustainable use of the natural resources, particularly the water. The water management must shift towards solutions acted to protect, safeguard, and sustainably use the available water resources. A new water scheme must be implemented, in which the waste paradigm must be overtaken and substituted with resource-oriented one.

Although water quality improvement is generally the primary objective of treatment wetlands, the creation of habitats is an inevitable outcome of these projects. Macroinvertebrate are often early colonists of new created wetlands, with abundance and diversity approaching high levels within a few years from wetland construction. A deeper knowledge of the biodiversity hosted in these environments is needed to evaluate if newly created ponds are appropriate management tools for biological conservation.

However, very little is known about the biochemical processes involved, and the use of constructed treatment wetlands in the removal of petroleum aromatic hydrocarbons from produced and/or processed water. Wastewaters from the oil industry contain aromatic hydrocarbons such as benzene, toluene, ethylbenzene and xylene (ortho, meta and para isomers), which are highly soluble, neurotoxic and cause cancer.

Résumé :

Diffuse agricultural pollution presents a major challenge to global water quality management, requiring the adoption of new land management practices such as constructed agricultural wetlands. These wetlands, promoted in agri-environment schemes, may effectively intercept rainfall-mobilised phosphorus (P), nitrogen (N) and carbon (C). However, wetlands may potentially facilitate ‘pollutant swapping’: the transfer of one form or pathway of pollution for another, as a result of mitigation efforts. Retained pollutants may be remobilised through solubilisation or as the greenhouse gases (GHGs): me

Résumé :

Eutrophication is a major problem causing algal blooms and impaired water quality, especially regarding coastal areas and seas. It is a result of an excessive supply of nutrients such as phosphorus (P), where agriculture accounts for the largest share of the anthropogenic nutrient load. Furthermore, arable fields with clay soils have been shown to have among the highest P-losses. In this study, 10 constructed wetlands located in agricultural areas with high clay content in the topsoil were examined. The aims were to investigate how the P accumulation is related to wetland design and catchment

Wastewaters from intensive agricultural activities contain high concentrations of nitrogen and phosphorus that contributes to water management problems. During the past few years, there has been considerable interest in the use of constructed wetlands for treating surface water runoff from farmyards. If the contaminated runoff is not treated, this wastewater along with other non-point sources of pollution can seriously contaminate the surface water and groundwater.

Résumé :

The frequency of on-site systems for treatment of domestic wastewater is increasing with new residential development in both rural and low-density suburban areas. Subsurface flow constructed wetlands (SFCW) have emerged as a viable option to achieve advanced or secondary treatment of domestic wastewater. The pollutant removal efficiency in SFCW depends on design parameters. Many of these factors have been investigated while others such as aspect ratio, design of water inlet structure and method of dosing the wetland have yet to be fully examined. This study examined the effect of aspect ratio

Despite the global acceptance for the application of vertical-flow constructed wetlands (VF CWs) as sustainable and cost-efficient technology in treating various types of wastewater, including urban wastewater, continuous loading of wetlands over time can lead to performance inefficiency and generate operational problems especially when high shock loads, such as petroleum hydrocarbon spills, are subjected to the system. Contamination with petroleum hydrocarbon compounds results in changing the structure, function and ecosystem service values of wetlands, which can eventually lead to clogging o

Horizontal Subsurface Flow Treatment Wetlands (HSSF TWs) are used by Severn Trent Water as a low-cost tertiary wastewater treatment for rural locations. Experience has shown that clogging is a major operational problem that reduces HSSF TW lifetime. Clogging is caused by an accumulation of secondary wastewater solids from upstream processes and decomposing leaf litter. Clogging occurs as a sludge layer where wastewater is loaded on the surface of the bed at the inlet. Severn Trent systems receive relatively high hydraulic loading rates, which causes overland flow and reduces the ability to min
