Industrial Pollution and Its Control

Article excerpt

Industrial waste waters when discharged untreated into water bodies results in serious water pollution. Such wastes vary widely in composition and may contain plant or animal wastes, acids, alkalis, oils, and other organic or inorganic chemicals some of which may be toxic, synthetic detergents or radioactive substances. The industrial waste laden bodies of water are put to subsequent uses for many other purposes which include water supplies for municipal and industrial purposes, water contact or non-water or non-water contact recreation, commercial fishing and agricultural irrigation. This multiple usage of natural waters and their importance for wide-ranging human activities emphasize the needs for a serious attention to the water pollution problem.

For the economic development of a country industrialization plays a vital role. Industrialization revolution in many countries has brought about environmental degradation and deterioration of great magnitude. Pakistan is no exception to it. The present scenario of rapid industrialization in Pakistan although would prove to be economically useful but it would also pose a much more serious threat of unprecedented magnitude to the environment. To meet the objectives of such industrial development programmes without posing pollution threat industrial pollution aspect should be given due consideration. It is important because if the industry is developed with a very specific objective of producing a useful material without taking into account the proper disposal of wastes and emissions produced as a result of its production, it is going to have a detrimental impact on the environment.

Most of the industries developed in this country have unfortunately given little attention to the control and management of their industrial waste water and gaseous emissions because of lack of proper guidance from knowledgeable authorities and due to severe personal costs that control would bring. At present the liquid industrial wastes are either discharged into natural bodies of water without proper treatment or applied to land without scientific and technical considerations. Similarly, no control measures have been adopted in most cases on the emissions of harmful gases from the industries. This practice is resulting in the deterioration of the environment in Pakistan. This deterioration is further aggravated by the fact that even municipal wastewater are also being discharged to natural bodies of water either untreated or partially treated. In Pakistan, the fact remains that sewage treatment plants lag behind the provision of sewerage systems development.
