Available in PDF, EPUB and Kindle. Book excerpt: FROM THE PREFACE Sanitary landfills are the most widely utilized method of solid waste disposal around the world. With increased use and public awareness of this method of disposal, there is much concern with respect to the pollution potential of the landfill leachate. Depending on the composition and extent of decomposition of the refuse and hydrological factors, the leachate may become highly contaminated. As leachate migrates away from a landfill, it may cause serious pollution to the groundwater aquifer as well as adjacent surface waters. There is growing concern about surface and groundwater pollution from leachate. Better understanding and prediction of leachate generation, containment, and treatment are needed. This book contains a literature review of various methodologies that have been developed for prediction, generation, characterization, containment, control, and treatment of leachate from sanitary landfills. The contents of this book are divided into nine chapters. Each chapter contains theory and definition of the important design parameters, literature review, example calculations, and references. Chapter 1 is devoted to basic facts of solid waste problems current status and future trends towards waste reduction and recycling. Chapter 2 provides a general overview of municipal solid waste generation, collection, transport, resource recovery and reuse, and disposal options. The current status of sanitary landfill design and operation, problems associated with the landfilling, and future trends are presented in Chapter 3. Methods of enhanced stabilization, recycling landfill space, methane recovery, and above grade landfilling, and closure and post closure care of completed landfills are also discussed in detail. Chapter 4 provides a general overview of Subtitle D regulations and its impact upon sanitary landfilling practices. Chapter 5 is devoted entirely to moisture routing and leachate generation mechanisms. Examples of calculation pr

This book was released on 2015-12-02 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Municipal solid waste (MSW) disposal is an ever-increasing problem in many parts of the world, especially in developing countries. To date, landfilling is still the preferred option for the disposal and management of MSW due to its low-cost operation. While this solution is advantageous from a cost perspective, it introduces a high level of potential pollutants which can be detrimental to the local environment. Control and Treatment of Landfill Leachate for Sanitary Waste Disposal presents research-based insights and solutions for the proper management and treatment of landfill leachate. Highlighting relevant topics on emerging technologies and treatment innovations for minimizing the environmental hazards of waste disposal, this innovative publication contributes to filling in many of the gaps that exist in the current literature available on leachate treatment. Waste authorities, solid waste management companies, landfill operators, legislators, environmentalists, graduate students, and researchers will find this publication beneficial to their professional and academic interests in the area of waste treatment and management.

This book was released on 1998-09-29 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Constructed 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.

This book was released on 2014-09-15 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wastewater treatment plants are large non-linear systems subject to large perturbations in wastewater flow rate, load and composition. Nevertheless these plants have to be operated continuously, meeting stricter and stricter regulations. Many control strategies have been proposed in the literature for improved and more efficient operation of wastewater treatment plants. Unfortunately, their evaluation and comparison – either practical or based on simulation – is difficult. This is partly due to the variability of the influent, to the complexity of the biological and biochemical phenomena and to the large range of time constants (from a few minutes to several days). The lack of standard evaluation criteria is also a tremendous disadvantage. To really enhance the acceptance of innovative control strategies, such an evaluation needs to be based on a rigorous methodology including a simulation model, plant layout, controllers, sensors, performance criteria and test procedures, i.e. a complete benchmarking protocol. This book is a Scientific and Technical Report produced by the IWA Task Group on Benchmarking of Control Strategies for Wastewater Treatment Plants. The goal of the Task Group includes developing models and simulation tools that encompass the most typical unit processes within a wastewater treatment system (primary treatment, activated sludge, sludge treatment, etc.), as well as tools that will enable the evaluation of long-term control strategies and monitoring tasks (i.e. automatic detection of sensor and process faults). Work on these extensions has been carried out by the Task Group during the past five years, and the main results are summarized in Benchmarking of Control Strategies for Wastewater Treatment Plants. Besides a description of the final version of the already well-known Benchmark Simulation Model no. 1 (BSM1), the book includes the Benchmark Simulation Model no. 1 Long-Term (BSM1_LT) – with focus on benchmarking of process monitoring tasks – and the plant-wide Benchmark Simulation Model no. 2 (BSM2).

Available in PDF, EPUB and Kindle. Book excerpt: In 1989, the US Geological Survey and Cornell University, in cooperation with the New York State Energy Research and Development Authority and the Tompkins County Solid Waste Department, began a three-year study at a municipal solid-waste landfill near Ithaca, New York, to test the effectiveness of leachate treatment with constructed wetlands and to examine the associated treatment processes. Specific objectives of the study were to examine: treatment efficiency as function of substrate composition and grain size, degree of plant growth, and seasonal changes in evapotranspiration rates and microbial activity; effects of leachate and plant growth on the hydraulic characteristics of the substrate; and chemical, biological, and physical processes by which nutrients, metals, and organic compounds are removed from leachate as it flows through the substrate. A parallel study at a municipal solid-waste landfill near Fenton, New York was conducted by researchers at Cornell University, Ithaca College, and Hawk Engineering (Trautmann and others, 1989). Results are described.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Sanitary landfills are the primary method currently used for municipal solid waste disposal in many countries. The landfill regulation state that the waste disposed must be previously pretreated, with a biologic or incineration treatment) and the organic content must not be more than 3% (determined as TOC) to assure a reduction of methane production. Moreover the landfill has to fulfill several requirements according the sealing (liner systems and surface system) and construction in order to guarantee a decomposition of the waste contained in it, as well as to minimize the generation of leachate. This leachate is formed as a consequence of the rainwater that infiltrates and percolates through the waste (primary leachate), as well as from the degradation of the biologic components inside the landfill (secondary leachate). There are lots of factors that interfere in the formation and composition of the leachate. The chemicals within the leachate vary over the time depending on the physical, chemical, and biological activities occurring inside the landfill. The quality and quantity of leachate vary depending on the age of the landfill, the climate, the landfill morphology, the surface conditions, the operation of it, the size of the landfill, the composition of the waste such as its compaction, as well as the moisture inside and the degree of rainwater infiltration. The result is a high concentrated leachate that must be treated before discharging it to the nature or to a common clarification plant. There are different methods that can be applied, this are mainly two, degradation methods (biological such as anaerobic or aerobic decomposition) and separating methods (like coagulation-flocculation, adsorption, flotation, chemical oxidation and advance oxidation process as well as several filtration technologies). This case study is about a municipal solid waste landfill, which contains two different parts of landfill with two kinds of waste. Neither of both parts of the landfill have surface sealing. The leachate generated is treated in a treatment plant that consists basically of three consecutive filters (a fabric filter, sand filter and fabric filter) and a further treatment consisting of a twostep reverse osmosis (RO) membranes. The concentrate expected out from the second RO is 10% concentrated respect the 100% of initial leachate that enters to the plant. But this percentage has raised to aproximately a 20%, and blocking problems have been occuring. The disposing of this output is very expensive, as well as the often cleaning and changing of the membranes due to the blocking of these ones. It has been seen they are two kinds of leachate, the black one and the brown one. When the leachate is brown, the second step of reverse osmosis is not able to operate because the membranes get blocked. The analysis of pH, conductivity, ions, organic content and suspended solids, of the black leachate were carried out and the results showed a reasonable reduction through the treatment process. Due to the observations it is believed that the brown leachate is generated because of an increase of the infiltration rainwater flow into the landfill, caused by an abrasion and elution of the ash wood from the incinerated waste. This water flow drags with it mineral matter such as inorganic compounds and salts, that probably be causing the blocking of the membranes. It is believed that the quality of the brown leachate is the one causing blocking problems in the RO membranes. It is proposed to proceed to follow the sample analysis procedure for the brown leachate than for the black leachate, adding potential redox and turbidity and color parameters. As alternatives it is recommended a new biological treatment or an additional flotation plant with chloridric acid. On the other hand, the capping of the landfill to prevent the infiltration of rainwater to avoid the generation of brown leachate.
