Draw the diagram of a double liner system of landfill and explain the functions of various components.

This PPT should be used as reference only. Reading books (mentionedin syllabus) is mandatory for the preparation of the examinations.Disposal of solid waste Sanitary landfill Garbage is spread out in thin layers, compacted and covered with clay/plasticfoam Bottom is covered with impermeable linings to prevent the percolation ofleachates. When the landfill is full, it is covered with clay, sand and gravels Monitoring wells are drilled near the landfill area Landfill gas (Methane) is produced. Composting It is done due to the shortage of landfill area Decomposed in oxygen-rich medium Nutrient rich manure is produced Incineration Burning of waste in very high temperature Initial cost is very high Dioxin, furan, lead, cadmium etc. can be released. So, battery or plastics should be removedbefore burning12/03/19This PPT should be used as reference only. Reading books (mentionedin syllabus) is mandatory for the preparation of the examinations.Noise Pollution Noise: Unpleasant/ unwanted sound Noise pollution: The noise propagates through the atmosphere thatleads to discomfort and health hazards is known as noise pollution. Noise measurement is expressed as Sound Pressure Level (SPL) SPL is a logarithmic ration of sound pressure to a referencepressure. International reference pressure is 2 X 10 -5 Pa. (average thresholdof hearing) Unit of SPL is decibel. Threshold of pain is 130 dB Types of noise: Continuous, Intermittent, Impact/Impulsive12/03/19
