DOWNLOAD EBOOKConstructed wetlands are proving to be the best natural treatment system for landfill leachates. Most of the contaminants in landfill leachates are degraded in treatment wetlands. Potential for long-term sustainability and significant cost savings are attractive features of this eco-technology. Documentation of the experience in this use of constructed wetlands has been limited. Constructed Wetlands for the Treatment of Landfill Leachates is the first compilation of the results of research from North America and Europe. Originally presented at an international symposium, this collection of papers offers the most recent research findings from the leading researchers in this new and innovative natural treatment system. Specific issues addressed in the text include: leachate characteristics, and the potential for treatability by constructed wetlands wetland treatment, processes and transformation use of constructed wetlands in cold climatic conditions assessment of the tolerance of wetland plants to the toxicity of leachates role of plants in the treatments of leachates integrated wetland systems performance of different wetland treatment systems cost comparisons of wetland technology vs. traditional treatment technologies The potential for environmental contamination due to leachates from landfills is increasing, and there is an urgent need to find ways and means to treat leachates in a sustainable way Constructed Wetlands for the Treatment of Landfill Leachates will provide an invaluable source of information on the subject for scientists, engineers, practitioners, policy makers, and regulatory officials.

DOWNLOAD EBOOKThe increasing application of constructed wetlands for leachate treatment is an ever-growing incentive for the development of better process design tools. This book provides a study that was conducted to investigate leachate treatment performance of horizontal subsurface flow constructed wetlands (HSSFCW) installed with water dispersal system, called Safety Flow(r) to produce a defined subsurface wetting pattern along the line and length of the system. A pilot scale HSSFCW with three parallel reactors was set up with dimensions of 2.45 m length x 0.20 m width x 0.40 m depth. All reactors were dosed using pre-treatment leachate effluent from a landfill in Malaysia. Out of the three reactors, Reactors A and C were planted with Thypha angustifolia, whilst reactor B was not planted and used as a control. In addition, reactor C was installed with water dispersal system. The performance of constructed wetlands system was evaluated from the effluent quality. The main parameters were organic matters, nutrients and heavy metals. The results from this study provide an important outlook for engineers, scientists, environmentalists and researchers in this area.

DOWNLOAD EBOOKMunicipal sanitary landfills generate leachate that New York State regulations require to be collected and treated to avoid contaminating surface water and groundwater. One option for treating leachate is to haul it to municipal wastewater treatment facility. This option may be expensive, may require excessive energy for transportation, and may require pretreatment to protect the receiving facility's processes. An alternative is on-site treatment and discharge. Personnel from the Town of Fenton, New York; Hawk Engineering, P.C.; Cornell University; and Ithaca College designed, built, and operated a pilot constructed wetland for treating leachate at the Town of Fenton's municipal landfill. The system, consisting of two overland flow beds and two subsurface flow beds has been effective for 18 months in reducing levels of ammonia (averaging 85% removal by volatilization and denitrification) and total iron (averaging 95% removal by precipitation and sedimentation), two key constituents of the Fenton landfill's leachate. The system effects these reductions with zero chemical and energy inputs and minimal maintenance. A third key constituent of the leachate, manganese, apparently passes through the beds with minimal removal. Details and wetland considerations are described.
