Journal ArticleDOI
Constructed wetlands for wastewater treatment
TL;DR: The first experiments using wetland macrophytes for wastewater treatment were carried out in Germany in the early 1950s and since then, the constructed wetlands have evolved into a reliable wastewater treatment technology for various types of wastewater as discussed by the authors.

The potential for constructed wetlands for wastewater treatment and reuse in developing countries: a review
TL;DR: The potential of constructed wetlands for wastewater treatment and reuse in developing countries by looking at the results of current research initiatives towards implementation of the technology in these countries is highlighted in this article.
Journal ArticleDOI
Effect of temperature, HRT, vegetation and porous media on removal efficiency of pilot-scale horizontal subsurface flow constructed wetlands
TL;DR: In this article, the effect of temperature, hydraulic residence time (HRT), vegetation type and porous media material and grain size on the performance of horizontal subsurface flow (HSF) constructed wetlands treating wastewater, five pilot-scale units of dimensions 3.m in length and 0.75m in width were operated continuously from January 2004 until January 2006 in parallel experiments.
Journal ArticleDOI
Emergent plants used in free water surface constructed wetlands: A review
TL;DR: The literature survey of 643 FWS CWs from 43 countries recorded 150 plant species and revealed that the most commonly used macrophyte genera were Typha, Scirpus (Schoenoplectus), Phragmites, Juncus and Eleocharis.
Journal ArticleDOI
Efficiency of constructed wetlands in decontamination of water polluted by heavy metals
TL;DR: In this paper, a twin-shaped constructed wetland comprising a vertical flow (inflow) chamber with Cyperus alternifolius followed by a reverse-vertical flow (outflow) chamber with Villarsia exaltata was assessed for decontamination of artificial wastewater polluted by heavy metals.

Natural Systems for Waste Management and Treatment
TL;DR: In this article, the use of wetlands and aquatic systems, the treatment of sludges, and other areas in the field of waste management are discussed, as well as current EPA regulations and coverage of small-scale on-site systems.

Plants for constructed wetland treatment systems — A comparison of the growth and nutrient uptake of eight emergent species
TL;DR: Allocation of above and below-ground growth and nutrient uptake, and pollutant removal were compared for Schoenoplectus validus, Phragmites australis, Glyceria maxima, Baumea articulata, Bolboschoenus fluviatilis, Cyperus involucratus, Juncus effusus and Zizania latifolia.
Journal ArticleDOI
Nutrient removal processes in freshwater submersed macrophyte systems
TL;DR: In this article, a recent development for the control of eutrophication is the application of ecological engineering, involving designed wetlands for water treatment, where submersed macrophytes play a crucial role by creating a favorable environment for a variety of complex chemical, biological and physical processes that contribute to the removal and degradation of nutrients.
Journal ArticleDOI
Nutrient content of wetland plants in constructed wetlands receiving municipal effluent in tropical Australia
TL;DR: Examination of tissue nutrient content in different species and plant components from 7 wetlands in Queensland found most species translocated to the constructed wetlands flourished indicating their ability to tolerate nutrient enriched waters, and tended to have higher nutrient concentrations than their controls in natural wetlands.
