incorporates
gas collection, storage and compressor system
leachate collection, storage and treatment facilities.
prevent leachate leakage into ground water
gas leakage detection p robes.
leachate monitoring well and ground water monitoring well
Design & operation SLF Several important factors must be
considered:
land area cover material cell design and construction equipment requirement personnel requirement financedrainage
spread and compaction water supply fire prevention facilities fencing - gatehouse operation time land use after completion of
landfill wheel cleaning notice board
Population protection site location rainfall temperatureSoil type windHydrological properties and water
table
compaction landfill
essential to reduce settlement
take about 2 years
prevent fire
eliminates odour, flies & vermin
for building structure – 10 – 12 years
ideally compacted fill should have density of 900 – 950 kg/m3
densities are measure by using backhoe method and auger method.
the values depend on:
Type of waste
Pretreatment
Composting of waste
Time of landfill
Moisture content
Type of landfill
Stage of compaction
Leachate
define as liquid that has percolated through solid waste and has extracted Dissolved or suspended material
average amount of leachate generated is 150L//tonne
contain organic matter, nitrogen (ammoniacal), suspended solid salts & colouring matter.
constration of eluted matters will be highest the first 3 – 8 years.
quantity of leachate produced depend on factors:
Soil type
Waste composition
Degree of composition
Rainfall
Evaporation
Landfill type and age
