Waste products from manufacturing plants are the common sources of pollution nowadays. Factory pollution accounts for almost 50 percents of all water pollution. There are many manufacturing factories that consume high volumes of water to convey waste products to different areas. The waste water from these factories ends up into seas, oceans and lakes.
We have construction related factories which emit poisonous substances such as gypsum, cement, metals and poisonous solvents. All these substances are deposited in fresh water and are likely to affect life of aquatic animals.
Power plants also lead thermal pollution. They tend to increase the water temperature, which disrupts the level of oxygen in the water. This is likely to kill animals and animal species found in water.
Most of the manufacturing plants emit poisonous gases such as carbon monoxide. This is produced during combustion and is actually dangerous to human beings. There are also other factories that emit sulphur oxides that cause the acid rain. This occurs after the fuel that contains sulphur is burned. These sulphur oxides are commonly produced by those power plants that are driven through combustion.
The common waste products from factories that can cause water pollution include; asbestos, mercury, nitrates, caustic soda and many more. In order to control factory emissions and prevent pollution, the governments should take legal action to those manufacturing plants emitting poisonous substances.
