LANDFILL LEACHATE AND GAS GENERATION - Coggle Diagram
LANDFILL LEACHATE AND GAS GENERATION
LEACHATE MANAGEMENT
Liquid that percolated through waste and has extracted dissolved or suspended material from it
Arises from biochemical and physical breakdown of waste
LANDFILL GAS : PRODUCT OF DEGRADATION OF BIODEGRADABLE WASTE (ORGANIC MATERIAL THAT CAN BE BREAK DOWN BY MICROORGANISM)
LEACHATE TREATMENT
On site treatment
Aerated lagoon
Wetland system
Evaporation
Reed bed
Polishing
LEACHATE FORMATION
By compacted clay cap and phytocap
Evaporation and transpiration occur
LEACHATE FROM EXTERNAL SOURCES
Runoff
Rainfall
Groundwater
Water from underground springs
LEACHATE COLLECTION
Perforated pipes run through landfill
Pipes carried leachate to collection pond
Leachate can be pump or flow by its gravity
LEACHATE MANAGEMENT OPTION
Recycling
Discharge
Evaporation
Leachate treatment
ADVANTAGES LEACHATE TREATMENT
Lowest cost
Prevent public disturbance
New habitat for wildlife
Potential for fertilizer production
LANDFILL GAS FORMATION
Using bio-window system
waste form methane and carbon dioxide gas by gravel distribution
TYPICAL CONSTITUENT FOUND IN MSW
Methane
Carbon dioxide
Nitrogen
oxygen
PARAMETER FOR RATE OF LG PRODUCTION
Waste input rate
Ambient PH
Ambient temperature
Waste density
Specific site management strategy
LANDFILL GAS COLLECTION
Passive gas collection system
Active gas selection system
LANDFILL GAS COLLECTION AND UTILIZATION SYSTEM
