MODERN SANITARY LANDFILL

1. MODERN SANITARY LANDFILL

2. Modern Sanitary Landfill • incorporates • gas collection, storage and compressor system • leachate collection, storage and treatment facilities. • prevent leachate leakage into ground water

3. gas leakage detection p robes. • leachate monitoring well and ground water monitoring well

4. Design & operation SLF • Several important factors must be considered: • land area • cover material • cell design and construction • equipment requirement • personnel requirement • finance • drainage

5. spread and compaction • water supply • fire prevention facilities • fencing - • gatehouse • operation time • land use after completion of landfill • wheel cleaning • notice board

6. Population protection • site location • rainfall • temperature • Soil type • wind • Hydrological properties and water table

7. compaction landfill • essential to reduce settlement • take about 2 years • prevent fire • eliminates odour, flies & vermin • for building structure – 10 – 12 years

8. 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:

9. Type of waste • Pretreatment • Composting of waste • Time of landfill • Moisture content • Type of landfill • Stage of compaction

11. Landfill design

12. Landfill design

15. Leachate • define as liquid that has percolated through solid waste and has extracted Dissolved or suspended material

16. 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.

17. quantity of leachate produced depend on factors: • Soil type • Waste composition • Degree of composition • Rainfall • Evaporation • Landfill type and age
