  • 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 ...

    The modular reed bed is an award winning, innovative solution for small footprint tertiary treatment. This case study follows the implementation of this technology on a small and remote sewage works which was overloaded during high rainfall. This project saved 91% in costs for the effected utility (which had a budget of £300k for the project) and provided a reduced health and safety risk ...

  • 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 ...

  • 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, ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Economic assessment of sludge handling and environmental impact of sludge treatment in a reed bed system

    The effect on the environment of the establishment and operation of a sludge treatment reed bed system (STRB) is quite limited compared to mechanical sludge dewatering, with its accompanying use of energy and chemicals. The assessment presented here of the investment, operation and maintenance costs of a typical STRB, and of the related environmental impact, is based on the experiences gained ...

  • 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 ...

  • Gas composition of sludge residue profiles in a sludge treatment reed bed between loadings

    Treatment of sludge in sludge treatment reed bed systems includes dewatering and mineralization. The mineralization process, which is driven by microorganisms, produces different gas species as by-products. The pore space composition of the gas species provides useful information on the biological processes occurring in the sludge residue. In this study, we measured the change in composition ...
