Industrial Waste Water Pros And Cons

This review shows the pros and cons of using the combination of various technologies for industrial waste water treatment plant. Rapid industrialization, intensive agriculture and other human activities cause soil degradation, pollution and lowers the productivity and sustainability of the crops that further increase the pressure on natural resources and contribute to their degradation. Environmental bio remediation is an effective management tool for managing the polluted environment and in restoring the contaminated soil. The use of microbial sources, coupled with advanced technology is one of the most promising and economic strategies for the removal of environmental pollutants. There is a strong scientific growth with both the in situ

Pollution is a global intimidation to the environment and it becomes an alarm word of today’s world. The swift growth of human populations fulled by scientific developments in health and agriculture has led to a speedy increase in the environmental pollution. Water has a major impact on all aspects of human life, including but not limited to health, food, energy and the economy. The unprecedented inhabitants’ multiplies and the industrial development during the 20th century has not only increased the conventional solid and liquid waste pollutants to critical levels but also produced a range of previously unknown pollution problems for which the society was unprepared. Of the total 220 million deaths per year it was estimated that the causes of death in 12-20 million are due to water and non-fatal infections which is very high(2). The run- off flow is considered to be the freshwater source on which the people depend. The steady flow of fresh water was estimated at 12.700 to 16.000 km3 year which is 4200 km3 per year. It is used for freshwater irrigation, industrial and domestic purposes, and that is estimated to increase by a number of 4350-5200km3 per year . Alternatively, the available fresh water is only 0.5% of the worlds 1.4 billion km3 water, which is also poorly distributed throughout the world (3). There is a limited ability to increase the supply of drinking water due to the competing demands of the growing populations worldwide and, the problems related to water. It is expected to further increase due to climatic changes and population growth over the next two decades. The most common method of wastewater treatment in the developed countries is centralized aerobic wastewater treatment plants and lagoons for both domestic and industrial waste water. It is estimated that the world 's population increases roughly by 2.9 billion people between now and 2050. The lack of
