Environmental Engineering :: essays research papers

Engineering is defined as the science based profession by which the physical forces of nature and the properties of matter be do useful to mankind in the form of structures, machines, and other products or processes at a reasonable cost of money and time. An engineer is a person skilled or skilled in designing and planning the performance of such equipment as machines and structures and in supervising their performance. An Environmental (or sanitary) Engineer is concerned with the water and cloaca treatment as well as the resi-dential and industrial wastes. Environmental engineers are trained in preventing, evaluating, and solving environmental problems. To be successful, environmental engineers moldiness blend technical knowledge with effective communication skills in day-to-day work and be able to communicate effictively with people of all types if they are to succeed in solving all of the problems facing them. The protection of rivers and lakes is part of their responsibilit y. In this profession, a know-ledge of chemistry and biology must be added to the engineering base. There are many different jobs that the enviorn-mental engineers have to do. First, there is Water Quality. Protecting the feeling of water required for human use andenvironmental protection is an crucial role for environmental engineers. Increasingly severe quality standards for drink-ing water, wastewater, pollutant, and groundwater require engineers and scientists trained in the theory and practice of water and wastewater treatment. In addition, environmental engineers must be able to predict the fate of contaminants in multimedia enironments in order to measure the effects of pollution on humans and ecosystems. Water quality engineering involves the application of environmental chemistry, microbiology and physics together with modeling and process engin-eering to address these areas.Second, there is Hazardous Waste Managment. Many industrial societies produce and shun of signifi cant amounts of hazardous materials. In sufficient treatment, storage and disposal have resulted in many uncontrolled contami- nant releases to the environment. Innovative engineering solutions are needed for liquid, gassy and solid hazardous wastestreams as well as for contaminated site remediation. It is the job of environmental engineers to understand and solvethese waste problems. Third, there is cinch Quality. Air pollution is a big problem in society today. Environmental engineers solve air pol-lution problems across a range of scales, with particular digest on indoor environments and urban air basins. They also haveto understand the physical and chemical processes that determine the concentrations, fates, and effects of air pollutants they
