B.Tech Environmental Engineering

About the Course :

* We humans have a long history of polluting our air, water, and soil. This contamination not only hurts nature, but is dangerous to people. Luckily, environmental engineers are on the job.
* Students in Environmental Engineering learn to design, develop, and evaluate structures, equipment, and systems that protect the environment from the effects of human activity and that improve public health and well-being.
* Overall objective of Environmental Engineering is to reduce the impact of human activities on the natural environment, and to create a more sustainable eco-system for future generations to live in.
* Presence of some of the best known pollution emitting industries and Government regulating bodies have made possible transfer of environmental technology in the country.
* The Six main sectors in this field are:-



o Pollutant Transport:
+ Environmental problems are essentially multi-physics problems and often involve transport of some substance.
+ Transport of contaminants and other substances may occur in the atmosphere, water bodies such as rivers, lakes or ocean. Sources of pollutants may be industrial and urban waste, agricultural pollution or saltwater intrusion in coastal aquifers

o Water Purefication:
+ This includes design or analysis of water treatment plants which are categorized as
# Sanitary Waste Treatment,
# Industrial Waste Treatment,
# Drinking Water Treatment.
+ It covers treatment of chemical, biological, and/or thermal waste, the purification of water and air.
o Wastewater Treatment:
+ This is the process of removing contaminants from wastewater and household sewage, both runoff (effluents) and domestic.
+ It includes physical, chemical, and biological processes to remove physical, chemical and biological contaminants. Its objective is to produce a waste stream (or treated effluent) and a solid waste or sludge suitable for discharge or reuse back into the environment. o Treatment removes unwanted constituents without affecting or altering the water molecules themselves, so that wastewater containing contaminants can be converted to safe drinking water.
+ Most treatment plants have primary treatment (physical removal of floatable and settle able solids) and secondary treatment (the biological removal of dissolved solids).
o Air Pollution:
+ This involves protecting environment from air pollution. Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or damages the natural environment, into the atmosphere.
+ The atmosphere is a complex, dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth's ecosystems.
o Solid Waste Treatment:
+ This offer technologies and consultancy services in Solid Water Treatment and management. The solid waste from Industrial kitchens, butchery house, segregated bio-degradable waste of Housing colonies can be treated to get valuable bi-products such as Bio methane gas for heating and rich fertilizer. The large quantity of Biogas can be converted in to Electricity for garden lighting.
o Hazardous Waste Management:
+ The Hazardous Substances Management Division (HSMD) is the nodal point within the Ministry for management of chemical emergencies and hazardous substances.
+ The main objective of the Division is to promote safe management and use of hazardous substances including hazardous chemicals and hazardous wastes, in order to avoid damage to health and environment.
