List and various plans taken for controlling air and water pollution also given details and plan
Answers
Pollution control is an essential task. There are four types of control: legal, social, economical, and technological measures, which help to prevent the pollution by various methods of operations. Waste products enter the environment in various forms and threaten the quality of the air, land, and water. The presence of waste products in water is especially serious, as many of these products can enter the food chain, where the biochemical processes can rapidly increase their concentration to toxic level. Hence, it is extremely important to study the methods of treating waste products and eliminating them from aqueous system. The US Environmental Protection Agency has listed copper as a priority pollutant.
Pollution control has almost become an integral part of the process of industrialization. Appropriate laws have been passed that restrict and regulate the growth of pollution intensive industries, especially in metropolitan cities. It has been made obligatory for industrial units to adopt measures to control pollution.
The pollution powers of plating wastes are reduced within the plant by several means. Many recommendations for modifications in design and operation to reduce wastes have been suggested. The Ohio River Valley Water Sanitation Commission has published a guide for these practices. Additional modifications include the following:
(1)
Installing a gravity-fed, nonoverflowing emergency holding tank for toxic metals and their salts
(2)
Eliminating breakable containers for concentrated materials
(3)
Designing special drip pans, spraying rinses, and shaking mechanism
(4)
Reducing spillages, drag-out, and leakage to the floor or other losses by curbing the area and discharging these losses to a holding tanks
(5)
Using high-pressure fog rinses rather than higher volume water washes
(6)
Reclaiming valuable metals from concentrated plating bath wastes
(7)
Evaporating reclaimed wastes to desired volume and returning to plating bath at rate equals to loss from bath
(8)
Recirculating wet washer wastes from fine scrubbers
