Industrial Pollution - Coggle Diagram
Industrial Pollution
Air Pollution
Caused by
high proportion of unwanted gases
like
sulphur dioxide, nitrogen dioxide
Airborne particulate matter
contains
solid & liquid particles like dust, sprays and mists
Toxic gas leaks
can be very hazardous
Water Pollution
Caused by
organic and inorganic industrial wastes and affluents discharged into rivers
Paper, pulp, chemical, textile, petroleum refineries
, etc. release
detergents, acids, dyes, salts untreated
Fly ash, phospo-gypsum and iron and steel slags
are the
major solid wastes in India
Thermal Pollution
Occurs when hot water from factories and thermal plants is discharged into water bodies before cooling
Land Pollution
Dumping of wastes like
glass, harmful chemicals, industrial effluents, packaging, etc. render the soil useless
Rain water percolates to the soil carrying pollutants which pollute ground water
Wastes from nuclear power plants cause cancer, birth defects and miscarriages
Noise Pollution
Cause
irritation
,
hearing 👂 impairment
,
increased ♥ rate and 🩸 pressure
Industrial and construction activities, machinery, factory equipment, etc. make a lot of noise
Control of Pollution
Minimizing used water by reusing recycling in successive stages
Rainwater harvesting
Treating hot water and effluents before releasing them in water bodies
Fitting smoke stacks to factories with electrostatic precipitators, fabric filters, scrubbers and inertial separators
Reducing smoke in factories by using oil or gas instead of coal
Machinery and equipment can be fitted with silencers to reduce noise pollution
NTPC
Optimum utilization of latest equipment
and
upgrading existing equipment
Minimizing waste generation
by
maximizing the use of ash
Providing green belts for nurturing ecological balance
; using
special vehicles for afforestation
Reducing pollution
through
ash pond management
&
ash water recycling
&
managing liquid waste
Ecological monitoring and reviews
