In chapter 7 the author goes into the wastewater process very deeply. In 300 words, describe your understanding of the entire process and the way you think the process will be changed in the future. Chapter 7 Water Process (Hazardous Waste Management: An Introduction By Clifton VanGuilder (2012) 7.5 WASTEWATER TREATMENT “The principle objective of wastewater treatment is generally to allow sewage and industrial effluents to be disposed without any danger to human health or damage to the environment. Conventional wastewater treatment consists of a combination of physical, chemical, and biological processes and operations to remove solids, organic matter, chemicals, and sometimes nutrients from wastewater. Wastewater treatment methods can be broadly classified as: • Physical unit operation: The removal of pollutants by physical forces. • Chemical unit operations: The removal of pollutants by addition of chemicals or by chemical reactions • Biological unit operation: The removal of pollutants by biological activities. These treatment methods occur in a variety of combinations in wastewater treatment systems, to provide various levels of wastewater treatment” [Raj 08]. The typical flow diagram for wastewater treatment is shown in Figure 7.1.
