Diverse industrial wastes have aggravated the problem of water pollution. This problem becomes complex because of the non-degradability of inorganic pollutants like heavy metals. Metals have received particular attention among other non-degradable toxic chemicals because of their adverse effects on aquatic life forms. To control water pollution, the immediate problems have to be solved by adopt...

Over the last decades with the rapid growth of industrial zones, manufacturing plants and the substantial urbanization, environmental pollution has become a crucial health, environmental and safety concern. In particular, due to the increased emissions of various pollutants caused mainly by human sources, the air pollution problem is elevated in such extent where significant measures need to be...

OBJECTIVE To evaluate the environmental and technical efficiencies of China's industrial sectors and provide appropriate advice for policy makers in the context of rapid economic growth and concurrent serious environmental damages caused by industrial pollutants. METHODS A data of envelopment analysis (DEA) framework crediting both reduction of pollution outputs and expansion of good outputs ...

Mathematical air pollution modeling represents an essential tool to control and predict atmospheric pollution. In this paper, a multiple cell model for the three-dimensional simulation of pollutants (SO2, CO, NOx, and TH) dispersion from a network of industrial stacks is presented. The model verification was conducted by checking the simulation results for a single stack against experimental da...

Most current pollution management in cities is based on treating pollution at the end-of-the pipe, after pollution is generated. This paradigm worked well for treating municipal sewage and industrial effluents – point sources of pollutants. Pollution from these sources has been greatly reduced since passage of the Clean Water Act in 1972. However, the remaining pollution problem in post-industr...

BACKGROUND One of Europe's most well-developed industrial regions is found in the Republic of Bulgaria. The industrialization of the region has a big impact on air pollution. Thermal power plant "Maritza East" (the largest of its kind in southeastern Europe), the army training range, machine manufacturers, household heating and high volume of automobile traffic are all major sources of pollutio...

Environmental pollution in India has increased from uncontrolled emission of chemical pollutants from the Industries, automobiles and non-point sources where modern agricultural practices are used. These chemicals have contaminated the air, water, soil and their residues have been detected in drinking water, food and consumer products. Some of these are very persistent in the environment and ha...

Water pollution is one of the major threats to public health in Pakistan. Drinking water quality is poorly managed and monitored. Pakistan ranks at number 80 among 122 nations regarding drinking water quality. Drinking water sources, both surface and groundwater are contaminated with coliforms, toxic metals and pesticides throughout the country. Various drinking water quality parameters set by ...

The exponential growth of Industrialization with the increase in human population has led to a heavy metal pollution problem, which has become ubiquitous from air to soil. Heavy metal pollution has become a more serious environmental problem in the last several decades as a result of its toxicity and insusceptibility to the environment. There are many bioremediation technologies including bioso...

the membrane separation technology by relying on microfiltration ultrafiltration, and reverse osmosis methods are becoming more important among consulting engineers, designers of environmental pollution control system, and industrial factories. the advantages of this technology together with its emphasis on recycling the fluid to the system and reusing the membranes have caused the membranes to...
