  • Reed Beds

    Naturally occurring wetlands have a natural, innate ability to remediate contaminants from water. Over the decades BritishFlora have supplied many millions of reeds, Phragmites communis, for both habitat creation projects such as bird reserves to attract bittern, bearded tit and water rails, to name but a few. Common Reed is commonly planted to help with the cleaning of contaminated ...

  • DNA polymorphisms reveal geographic races of reed canarygrass

    Reed canarygrass (Phalaris arundinacea L.) is a cool-season perennial with a circumglobal distribution in the northern hemisphere, native to Europe, Asia, and North America. Repeated introductions of European germplasm into North America have created confusion over the origins of reed canarygrass germplasm found in wetlands, pastures, and breeding programs. The objectives of this study were to ...

  • Processing Wastewater through Reed Beds: BHP Steel Long Products Division

     In the semi-arid region surrounding Whyalla in South Australia, BHP is creating an artificial wetland that promises to make its effluent cleaner than its input water. The wetland is projected to cost around 40% of a conventional treatment works, with significantly less operating costs. The project will conserve one of the most precious resources in the world’s driest country - water - and ...


  • Six examples of wastewater reuse after reed bed treatment

    The U.A.E. receives infrequent and irregular rainfall, totalling less than 130 mm per year. Temperatures range from 10°C to 48°C. Both industries and the population in the U.A.E. are growing very fast and public infrastructure is struggling to keep up with the exploding volume of sewage. The aim of these projects is to demonstrate applicable wastewater reuse options for individuals, ...

  • Sewage sludge and waterworks sludge stabilization in sludge treatment reed bed systems

    In this study, results about sludge stabilization in sludge treatment reed bed (STRB) systems in two different systems, Hanningfield STRB 1 (England), treating waterworks sludge, and Stenlille STRB 2 (Denmark), treating surplus activated sludge, are presented. The study mainly focused on the effectiveness of the STRBs systems in stabilizing sludge organic matter; in fact, parameters correlated ...

  • Sludge treatment reed bed facilities – organic load and operation problems

    The dewatering of the sludge with loss on ignition between 50 and 65% will have a maximal drainage on the order of 0.008–0.020 L/s/m2. Dewatering of the sludge with loss of ignition higher than 65% of dry solids will have a maximal drainage on the order of only 0.001–0.004 L/s/m2, approximately five to 10 times lower. It can be seen that there is a tendency for the achievable dewatering result to ...

  • Reed bed systems for sludge treatment: case studies in Italy

    In recent years, reed bed systems (RBSs) have been widely considered as a valid technology for sludge treatment. In this study are presented results about sludge stabilization occurring within beds in four RBSs, situated in Tuscany (Italy). The results showed that stabilization of the sludge over time occurred in all RBSs, as shown by the low content of water-soluble carbon and dehydrogenase ...

  • Greenhouse gas emissions from sludge treatment reed beds

    Sludge treatment reed bed systems (STRBs) are considered as an alternative technology for surplus sludge treatment. Organic matter is decomposed by various microbial reactions, resulting in gases such as CO2 and CH4 emitting into the atmosphere. The aim of this study is to investigate gas emission from STRBs. The static transparent chamber was adopted to measure gas emission; it allows ...

  • Organic matter stabilization in reed bed systems: Danish and Italian examples

    In this study, results about sludge stabilization in reed bed systems (RBSs) after the entire period of operation in two different systems situated in Denmark (Helsinge 42,000 population equivalent (p.e.) – 10 years) and in Italy (La Fontina, 30,000 p.e. – 6 years) were presented. In order to evaluate the process of sludge stabilization, parameters that highlighted the biochemical ...

  • The landfill leachate evapotranspiration in soil?plant system with reed Phragmites australis

    Using of the reed – Phragmites australis – is an effective method of landfill leachate disposal. In presented two years' study the effectiveness of leachate evapotranspiration from systems with reed was investigated. Daily evapotranspiration was in the range from 1.01 mm/d to 3.15 mm/d in the first year of research and from 2.68 mm/d to 4.94 mm/d in the second year. The research showed that the ...

  • Cost saving reed bed refurbishment innovation - Case Study

    Greener Waste Technology has designed a reed bed remediation programme that avoids the need to remove media or replace reeds. The process is a hybrid scheme incorporating the modular sludge settlement chambers utilised in the Modular Reed Bed system and the existing asset which is already in place. This type of remediation saves on project timescales and reduces risk as well as cost. The ...

  • Dewatering sludge originating in water treatment works in reed bed systems

    The dewatering process of the liquid water works sludge was examined in a trial with a series of six trial beds, each 20 m2. These were monitored from April 2008 to June 2010. It is possible to get the vegetation to grow in ferric sludge (∼300,000 mg Fe/kg dry solid, pH 7,7). It has not been necessary to use fertilizer. The influence of the loading programs (15–50 kg dry solid/m2/year) was tested ...

  • Short-term performance analysis of sludge treatment reed beds

    Sludge treatment reed beds (STRBs) represent an established technology for managing sludge produced by wastewater treatment plants (WWTPs). In this study, an analysis conducted on sludge stratigraphy in a STRB serving the municipal WWTPs of Helsinge (42,000 person equivalent, Denmark) is presented. The STRB has been in operation since 1996. The analysis was conducted for four months including ...

  • Operational strategy, economic and environmental performance of sludge treatment reed bed systems – based on 28 years of experience

    Sludge treatment reed bed (STRB) systems have been used for dewatering and mineralisation of sludge in Europe since 1988. STRB systems provide substantial environmental, economic, and operational benefits compared to mechanical sludge dewatering solutions such as belt presses and centrifuges. They require less energy, no chemicals, reduce the sludge volume and produce bio solids with dry solid ...

  • Reed beds facilitate transfer of tributyltin from aquatic to terrestrial ecosystems through insect vectors in the Archipelago Sea, SW Finland

    Due to their adsorptive behavior, organotin compounds (OTCs), such as tributyltin (TBT), are accumulated in aquatic sediments. They are resistant to biodegradation and, despite a ban in 2008, a potential source for future exposure. Sediment OTCs have mostly been measured from sites of known high concentrations such as ports, shipping lanes, and marine dredging waste sites. However, the possible ...

  • Kinetics of organic matter and ammonia removal in horizontal reed beds treating wastewater in Nepal

    In Nepal, both horizontal bed and vertical bed subsurface flow constructed wetlands have been used for wastewater treatment. However, these units were designed based on the empirical findings from other countries. The rational design criteria developed so far has some limitations as the performance of the units is sensitive to the behaviour of the microorganisms, climatic conditions and other ...
