  • 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 ...

  • 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 ...

  • 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. ...

  • 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 ...

  • Wetlands International Annual Review 2010

    Our annual review provides a great and global overview of all our achievements, our projects, our publications and other products, our donors and our financial situation. Conserving wetland biodiversity 2010 was the International Year of Biodiversity, which culminated in the Nagoya conference on the Convention for Biological Diversity (CBD). Thanks to the work of our team, the ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Treatment performance of a constructed wetland during storm and non-storm events in Korea

    The efficiency of a free water surface flow constructed wetland (CW) in treating agricultural discharges from stream was investigated during storm and non-storm events between April and December, 2009. Physico-chemical and water quality constituents were monitored at five sampling locations along the flow path of the CW. The greatest reduction in pollutant concentration was observed after passing ...

  • Improving the reliability of closed chamber methodologies for methane emissions measurement in treatment wetlands

    Non-homogeneous mixing of methane (NHM) within closed chambers was studied under laboratory conditions. The experimental set-up consisted of a PVC vented chamber of 5.3 litres of effective volume fitted with a power-adjustable 12 V fan. NHM within the chamber was studied according to fan position (top vs lateral), fan airflow strength (23 vs 80 cubic feet per minute) and the mixing time before ...

  • 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 ...

  • Balancing Wetland Regulation with Stormwater Management on a Watershed-Wide Basis: A Case Study.

    Maryland reconciles rapid growth, water-quality goals, and habitat protection. In response to increasing regulatory authority over its water resources, the Maryland Department of the Environment (MDE) has combined various programs and processes into a 'one-stop shop' where various issues can be addressed in a uniform and consistent manner. As part of this process, onsite conditions are assessed, ...

  • 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 ...

  • 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 ...
