Industrial And Hazardous Waste Management
Consider that in your process design work for this unit you are still attempting to reduce the constituents of concern (analytes on the lab report of your course project) to meet the local limits as an influent for the municipal wastewater treatment plant (WWTP). You have effectively engineered both a physical and chemical treatment into your system design during Unit II and Unit III. In this unit, you are considering the difficult process of engineering a biological treatment (secondary treatment) process into your treatment design. Two of the most relevant aspects of secondary treatment are aerobic treatment and anaerobic treatment. Consider Bahadori’s (2014, pp. 104-107) comments regarding the need for these two different treatment processes to be operated in tandem within a system.
Compare and contrast the benefits and limitations of a conventional API oil-water separator against a rotary drum oil skimmer.
Discuss application techniques and volume requirements as they relate to flow equalization basin design.
Discuss the importance of particle size and water temperature as they relate to sedimentation theory.
Describe a dissolved air flotation (DAF) unit and discuss the benefits, limitations, and applications for DAF unit use.
Using Bahadori’s (2014, pp. 105-106, 108) Table 4.3 and Table 4.4 as guides, what are the significant benefits and limitations of both aerobic and anaerobic treatment strategies?
