Environmental engineering is a professional engineering discipline that focuses on improving the quality of the environment and protecting the health of living organisms through the application of scientific and engineering principles. It falls under the domain of civil engineering and chemical engineering. An understanding of how technological advances affect the environment, and the local and global environmental effects of global warming, water and air pollution, and acid rain is vital to environmental engineering. This field enables solutions for water and air pollution control, waste disposal, wastewater management, recycling and public health. It also focuses on the evaluation of hazardous waste management systems, design of industrial wastewater treatment plants and municipal water supply systems, as well as the improvement of sanitation in rural, urban and recreational areas. This book brings forth some of the most innovative concepts and elucidates the unexplored aspects of environmental engineering. While understanding the long-term perspectives of the topics, the book makes an effort in highlighting their impacts as a modern tool for the growth of the discipline. The readers would gain knowledge that would broaden their perspective about environmental engineering.
