4. Describe the working of the electrostatic precipitator.
The electronic precipitator removes 99% of particulate matter which is present in the exhaust using a thermal power plant:
The electrode wires provide a corona releasing electrons and are maintained at several thousand voltages.
These electrons get attracted towards the dust particles. They also offer a negative charge to these particles.
The plates that collect the particles are grounded and get attracted towards the dust particles.
The plates should have air with low velocity so that dust particles can fall.
5. What are the characteristics and uses of the modern landfill site?
(a) Characteristics:
To prevent waste from being blown by wind, integument and compaction is done.
To contain leachates such as plastic liners or lining clay, procedures are done.
Landfill gas extraction systems are installed for extracting gas which is used in the generation of power.
(b) Uses:
They help in the prevention of waste through recovery and recycling of waste.
To prevent the essential transport of waste, a uniform cost for the disposal of waste is created.
They help in decreasing the risk to the environment and human health that emerged from the wastes.
