Environmental Engineering Practice Test: Other Treatment Methods — Flashcards

Environmental engineers use a variety of methods to treat environmental issues, including:
 

Water treatment: Environmental engineers assess the movement of water and the systems that store and treat it. This includes treating water to prevent illnesses and make it palatable.
Recycling: Recycling is a basic method of reducing pollution. It involves transforming waste resources into new materials and commodities.
Wastewater treatment: Environmental engineers design wastewater treatment plants to clean water before it's discharged into bodies of water. They use biological and mechanical processes to remove solids and contaminants from wastewater.
Site remediation: Also known as site rehabilitation, site remediation is a systematic process to detect, assess, and eliminate contamination from polluted sites.
Disinfectant: Drinking water purification is typically achieved by adding a disinfectant. Chlorine is the most common disinfectant used because it's inexpensive and destroys a large number of pathogens.
Filtration: Environmental engineers develop methods of filtration of effluents before discharging them into water or air.
Aeration: Aeration is a technique for the maintenance and rejuvenation of ponds and lakes. It helps mitigate algal blooms, organic sediment accumulation, noxious odors, reduced water clarity, and fish kills.
Biological treatment: Biological treatment purifies municipal and industry wastewaters by using common bacteria and other microbes.
Geotechnical aspects of solid waste: Geotechnical engineers study soil and groundwater contamination, waste disposal, and other environmental issues related to the earth's subsurface.

Topics include: Removal of Iron, Manganese, Colour, Odour and Taste, Activated Carbon Treatment, Fluoridation and Defluoridation, & Desalination.
