Thermal pollution. Wastes from nuclear power plants, nuclear and weapon production facilities cause cancer and birth defects. Measures to control air pollution: Particulate matter in the air can be reduced by fitting smoke stacks to factories with fabric filters, electrostatic precipitators etc.
Smoke can be reduced by using oil or gas instead of coal in factories. Water pollution caused by industries can be controlled by: Minimizing the use of water for processing by reusing and recycling. Harvesting of rain-water to meet water requirements of industries and other domestic purposes. Treating hot water and effluents before releasing them in rivers and ponds in the following ways: Primary treatment by mechanical means such as screening, grinding, flocculation and sedimentation.
Secondary treatment by biological process. Tertiary treatment by biological, chemical and physical processes. This involves recycling of waste water. Optimum utilization and up-gradation of equipment by adopting latest techniques. Minimizing waste generation by maximizing ash utilization.
Providing green belts for nurturing ecological balance. Reducing environmental pollution through ash pond management, ash water recycling system and liquid waste management. Ecological monitoring, reviews and online data base management for all its power stations. Steps to minimize the environmental degradation caused by industrial development: Minimizing use of water for processing by reusing and recycling in two or more successive stages.
Harvesting of rain water to meet domestic and industrial water requirements. Tea bushes require warm and moist frost-free climate all through the year with frequent showers that ensures continuous growth of the tender leaves. It is majorly grown in the following regions:.
