Chapter 6 · Question 5
Suggest measures to control industrial pollution.
Answer
Direct Answer
Industrial pollution can be controlled by treating wastewater before discharge, using cleaner fuels, fitting smoke filters and electrostatic precipitators, recycling water, reducing noise, managing hazardous waste safely, and following environmental standards strictly.
Simple Explanation
Control pollution by treating wastewater, using cleaner fuels, installing filters, recycling water, reducing noise, safely handling hazardous waste, and enforcing environmental standards.
Exam-Ready Structure
Industrial pollution can be controlled through a combination of technology, regulation, and management practices:
Water pollution control:
• Treating effluents in treatment plants before discharging into rivers or lakes.
• Recycling and reusing water within the factory to minimise fresh water intake and waste discharge.
• Properly disposing of toxic chemicals and heavy metals rather than dumping them.
Air pollution control:
• Installing smoke filters, scrubbers, and electrostatic precipitators in chimneys to capture particulate matter before it enters the atmosphere.
• Switching to cleaner fuels such as natural gas instead of coal and furnace oil.
• Maintaining machinery properly to ensure efficient combustion and lower emissions.
Noise pollution control:
• Enclosing noisy machinery and using sound-absorbing materials.
• Locating industries away from residential areas.
• Providing workers with hearing protection equipment.
Land pollution control:
• Treating and safely disposing of solid and hazardous waste rather than dumping on open land.
• Encouraging recycling of scrap metal, paper, and other industrial waste.
Policy measures:
• Strict enforcement of environmental laws and standards by pollution control boards.
• Encouraging industries to adopt cleaner production techniques through incentives and awareness.
• Regular monitoring of emissions and effluents from industries.
Key Points
- Industrial pollution can be controlled by treating wastewater before discharge, using cleaner fuels, fitting smoke filters and electrostatic precipitators, recycling water, reducing noise, managing hazardous waste safely, and following environmental standards strictly.
