Which factor influences the leachate quality?
Eckenfelder and Musterman1 list landfill age, ambient air temperature, precipitation and refuse permeability, depth, temperature, and waste composition as factors that affect leachate quantity and composition. Further, they observe that as landfills age, readily degradable organics undergo anaerobic degradation.
What is the effect of leachate?
Medical Literature tells us that some general health conditions caused by consuming leachate contaminated water can range from sweating, bleeding stomach disorders, to blood disorders, congenital disabilities and even cancer.
What are the factors affecting the landfill gas and leachate generation?
What conditions affect landfill gas production? The rate and volume of landfill gas produced at a specific site depend on the characteristics of the waste (e.g., composition and age of the refuse) and a number of environmental factors (e.g., the presence of oxygen in the landfill, moisture content, and temperature).
Which of the following is factors affects the leachate generation?
Similarly, there are many factors which may affect the composition of municipal solid waste landfill leachate. Some of the factors are for e.g. waste composition, depth of waste, moisture content, available oxygen, temperature, co-disposal with inclinator ash, waste processing, age of landfill, and toxicity.
How does leachate affect the environment?
The leachate from Municipal Solid waste landfills is a highly concentrated “chemical soup”, so concentrated that small amounts of leachate can pollute large amounts of groundwater, leaving it unsuitable for domestic water use.
What are the factors that are affecting the composition and characteristics of solid wastes?
What is the composition of landfill gas?
Landfill gas is composed primarily of 50 percent methane and 50 percent carbon dioxide and other gases produced at less than 1 percent. Methane and carbon dioxide are generated through the biological decomposition of waste.
What causes the composition of leachate to change?
The composition of leachate greatly depends on the age of the landfill and also on the process occurring in that age. The landfill cannot fill at a time and therefore contains many cells and section and experiences different pressure condition, this might occur different phase simultaneously within one landfill.
What are the factors that affect the composition of landfill leachate?
Similarly, there are many factors which may affect the composition of municipal solid waste landfill leachate. Some of the factors are for e.g. waste composition, depth of waste, moisture content, available oxygen, temperature, co-disposal with inclinator ash, waste processing, age of landfill, and toxicity.
What kind of treatment is needed for landfill leachate?
Landfill leachate, especially from mature and stabilized landfills, contains high concentrations of organic and inorganic compounds that inhibit the performance of conventional biological treatment. Different types of chemical oxidation, including ozonation, have been attempted to improve the treatability of landfill leachate (Beltrán, 2003 ).
How are leachate drainage layers considered small aquifers?
See image at the Web site of Biometallurgical Pty Ltd. www.users.bigpond.com/BioMet/photos/photos1.htm. Accessed May 13, 2004. Leachate drainage layer Drainage layers are considered as small aquifers: flow characteristics defined in terms of transmissivity (or thickness and hydraulic conductivity), length, and width
