It should be designed such a way that it can collect higher volume of water, as recirculation is being practiced in bioreactor landfills i.e., the size of the pipe or the pumping capacity will be greater than in case of convectional landfills. In case of enhanced biodegradation activity, there are chances for the fine particles to clog and so the filter and operational layers should be designed around the leachate collection pipe system. <a href=\"http:\/\/www.epgco.com\/\">http:\/\/www.epgco.com\/<\/a><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li>Gas collection and control systems &#8211; The accelerated decomposition of waste in the bioreactor landfills makes it mandatory that the gas collection system should be installed from the early phase of the landfill operation. <a href=\"http:\/\/www.prm-net.com\/landfill-gas-equipment\">http:\/\/www.prm-net.com\/landfill-gas-equipment<\/a><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li>Daily Cover &#8211; Should not impede downward movement of liquids or gas capture the cover material can be mixed with agricultural wastes such as composted yard wastes, etc. These materials degrade and can be placed over the solid waste lifts. Other alternative cover materials include polymer foams, slurry sprays, sludge, reusable geosynthetics and geotextile. The geotextile has a higher advantage compared to these other materials. i.e. It can control the rate of precipitation and infiltration into the landfill. For bioreactor landfills, a final cover may not be placed until most of the settlement has occurred. Instead, a temporary cover may be placed.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><u>Bioreactor Operation Considerations: <\/u><\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<p><strong>Liquid Recirculation &#8211; <\/strong>To optimize the effectiveness of a liquids recirculation program, one operator has found that dosing the landfill rather than continuous application was more beneficial. Dosing was accomplished by intermittently injecting liquids into the landfill trenches. This is done by letting the liquids seep into the landfill and then applying additional liquids to the trenches on a periodic basis.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Daily Cover<\/strong> &#8211; Recirculated liquid must be free to move within the landfill. Highly compacted soil daily cover creates barriers within the landfill. Options for daily cover that are more compatible with recirculation include tarps, plastic sheeting, and foam. It is also possible to use a highly permeable cover such as sand or to strip the daily cover off at the beginning of each new working day. For recirculation and bioreactor sites, it may be helpful to slope the daily cover (or top of trash) surface back in towards the landfill.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Working Face<\/strong> &#8211; The working face should be pre-wetted. Pre-wetting the waste at the working face has the advantages of increasing the moisture content of the waste, improving compaction and reducing windblown litter.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Landfill Gas &#8211;<\/strong> Bioreactors generate LFG earlier in the process and at a much higher rate than the traditional landfill. Bioreactor LFG is generated over a shorter period of time because the LFG emissions begin early and decline as the accelerated decomposition process depletes the source waste.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Final Cover &#8211;<\/strong> The timing for application of final cover will have to be considered in light of operational and permit requirements. To take advantage of the airspace increase created by liquids recirculation, the cell should stay open without a final cap as long as possible.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Odor &#8211; <\/strong>An aggressive odor control plan should be developed for virtually all landfills, but it is essential for recirculation\/bioreactor operations. Some operators have experienced increased odor problems that seem to be related to the recirculation of leachate.<\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<p><strong>Compaction &#8211; <\/strong>The highly compacted (tight) layers of trash reduce the ability of moisture to evenly saturate the mass and may cause problems with leachate outbreaks. To optimize recirculation effectiveness, it may be more efficient to do an initial loose compaction and then follow at some later time with more rigorous compaction (top 40-50 feet) after moisture has been well distributed.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Winter Operations &#8211; <\/strong>Liquids recirculation can be continued in winter months, particularly in buried pipe distribution systems. It may be necessary to provide freeze protection to aboveground components of the system.<\/p>\n<p>&nbsp;<\/p>\n<p>Landfills will continue to play an important part in the management of solid waste.\u00a0 With the advent of the design and construction of Bioreactor Landfills the problems such as contaminated leachate, air pollution, reduced closure cost, and being consistent with sustainable design will further protect human health and the environment.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Abs: A bioreactor landfill is a MSWLF that operates to rapidly transform and degrade organic waste.
