  • Pollutant monitoring in sludge treatment wetlands

    Phragmites australis for sludge dewatering and stabilization processes have been widely proved. The presence of reeds, indeed, efficiently allows solids dewatering and organic matter stabilization in order to obtain a stabilised product that can be suitable for land application, even if its environmental impact has to be considered. The actual revision of the European Union's Working Document on ...

  • Performance characterisation of a constructed Wetland

    Performance of a constructed wetland is commonly reported as being variable due to the site specific nature of influential factors. This paper discusses the outcomes from an in-depth study which characterised the treatment performance of a wetland based on the variation in the runoff regime. The study included a comprehensive field monitoring of a well-established constructed wetland in Gold ...

  • African Cranes, Wetlands and Communities

    It is encouraging to note that there are numerous crane and wetland conservation projects being implemented in various African countries. In this 11th edition of the African Cranes, Wetlands and Communities Newsletter, we have a mix of stories from the field covering three geographical regions – East Africa, Southern Africa and West Africa. The articles reflect the diverse issues that have ...

  • What is wetland mitigation banking?

    A mitigation bank is a wetland, stream, or other aquatic resource area that has been restored, established, enhanced, or (in certain circumstances) preserved for the purpose of providing compensation for unavoidable impacts to aquatic resources permitted under Section 404 or a similar state or local wetland regulation.  The concept has been around since the 1970’s.  In 1995 U.S. federal agencies ...

  • Water quality monitoring in wetland ecosystems using microbial model communities

    This study reviews the concept of model communities for water quality assessment in aquatic ecosystems. The feeding habits of protozoans were used to unite species into functional, trophic groups. Colonising communities were dominated by bacterivorous Flagellate Species (Sf). A new Index of Periphyton Flagellates (IPF) as an indicator of the trophic status of a water-body was developed. ...

  • Unique Chinese wetland park monitors water 24/7

    Project background The Deyang area in southwest China was struck hard by an earthquake in 2008. Since then, reconstruction has taken place with a tremendous speed and the urban population grew exponentially. Due to this urbanisation, the city’s water supply system can not meet its rapidly growing water demand. Currently, two-thirds of ...

  • Start-up readiness of the Apache wetland.

    The Apache Wetland was constructed in 1997 pursuant to a U.S. Environmental Protection Agency order to treat nitrate-contaminated groundwater within the Apache Powder Superfund Site. To date, the treatment facility is entering its fourth growing season in an effort to accumulate sufficient carbonaceous detritus of principally decayed Typha latifolia biomass. This substrate is required to maintain ...

  • Adaptive neuro-fuzzy inference system for real-time monitoring of integrated-constructed wetlands

    Monitoring large-scale treatment wetlands is costly and time-consuming, but required by regulators. Some analytical results are available only after 5 days or even longer. Thus, adaptive neuro-fuzzy inference system (ANFIS) models were developed to predict the effluent concentrations of 5-day biochemical oxygen demand (BOD5) and NH4-N from a full-scale integrated constructed wetland ...

  • Housing development wastewater treatment and constructed wetland disposal system

    Location: Sooke, BC Owner: Frances Gardens Housing Co-op Society Description: Innovative treatment and disposal design in an area of poor soils, including four-cell constructed subsurface flow wetlands to provide tertiary treatment of effluent from a 49 m3/d extended aeration activated sludge treatment plant. The renovated effluent from the ...

  • Controlling urban stormwater pollution by constructed wetlands: a Canadian perspective

    During the past 20 years, Constructed Stormwater Wetlands (CSWWs) have attained broad acceptance in Canada as effective measures for stormwater management. CSWWs are used mainly for improving stormwater quality by providing sufficient treatment volumes in shallow permanent pools. This leads to high requirements for land, which is one of the constraints on CSWWs use. Even though CSWWs perform less ...

  • Spatial pattern analysis for water quality in free-surface constructed wetland

    Free-surface constructed wetlands are known as a low-energy green technique to highly decrease a wide range of pollutants in wastewater and stormwater before discharge into natural water. In this study, two spatial analyses, principal factor analysis and hierarchical cluster analysis (HACA), were employed to interpret the effect of wetland on the water quality variables (WQVs) and to classify ...

  • A practical guide for the development of a wetland assessment method: the California experience

    ABSTRACT: Wetland rapid assessment methods (RAMs) can provide a cost effective, scientifically defensible estimate of wetland and riparian condition for use in ambient and project monitoring in resource management and regulatory programs. Those who have chosen to develop a RAM to assess wetland and riparian condition are faced with a range of issues and important choices that they must make ...

  • French vertical-flow constructed wetland design: adaptations for tropical climates

    The French Outermost Regions are under tropical climate yet still have to comply with both French and EU regulations. French vertical-flow constructed wetland systems appear well adapted to the technical specifics of these regions but their adaptation to tropical climate requires new design guidelines to be defined (area needed, number of filters, type of plants, material to be used, etc.). A ...

  • Performance of a pilot showcase of different wetland systems in an urban setting in Singapore

    The Alexandra Wetlands, part of PUB's Active, Beautiful, Clean Waters (ABC Waters) Programme, showcase a surface flow wetland, an aquatic pond and a sub-surface flow wetland on a 200 m deck built over an urban drainage canal. Water from the canal is pumped to a sedimentation basin, before flowing in parallel to the three wetlands. Water quality monitoring was carried out monthly from ...

  • Design, construction and performance of a horizontal subsurface flow wetland system in Australia

    Malabugilmah is a remote Aboriginal community located in Clarence Valley, Northern NSW, Australia. In 2006, seven horizontal subsurface flow wetland clusters consisting of 3 m × 2 m wetland cells in series were designed and constructed to treat septic tank effluent to a secondary level (Total Suspended Solids (TSS) < 30 mg/L and Biochemical Oxygen Demand (BOD5) <20 mg/L) and ...

  • Characteristics of nutrient retention in a stormwater wetland during dry and wet days

    A 0.23-ha pilot wetland was constructed to examine its effectiveness for the control of nonpoint source pollution (NPS) from a 7.42-ha agricultural watershed in Korea. The wetland was operated during base flow and storm flow conditions and monitored for four years (2006–2009). The wetland was operated under high hydraulic loading rates (HLRs, 0.78 m/day on average) during rainy days. The average ...

  • Modelling removal of microbiological contaminants along a series of constructed wetlands

    The rate of removal of microbial pollutants along a series of constructed wetlands for treating wastewater in Covenant University, Ota, Nigeria were monitored from inlet to the discharge point into river Atuara and at 300 m upstream and downstream. The microbiological test results analysed were those of most probable number (MPN) of coliforms ( Escherichia coli ), coliform counts in cfu/100 ...

  • Multi-stage constructed wetland systems for municipal wastewater treatment

    In the present paper the detailed design and performances of two municipal wastewater treatment plants, a four-stage constructed wetlands (CW) system located in the city of Dicomano (about 3,500 inhabitants) in Italy, and a three-stage CW system for the village of Chorfech (about 500 inhabitants) in Tunisia, are presented. The obtained results demonstrate that multi-stage CWs provide an ...
