Unformatted text preview: b. Briefly explain how each impacts treatment decisions. c. Briefly define any impacts the sludge treatment system can have on the "source" system generating the sludge being treated. d. Briefly describe one example of how the daily operations and problems of the "source" system generating sludge to be treated can have an adverse impact the sludge treatment system performance. (25%) 4. Sludges from three processes is to be blended prior to treatment. The following table lists the characteristics of each of these sludge streams. Characteristic Waste Stream 1 2 3 Flow (gal/day) 2500 500 6000 Solids Concentration (%) 0.9 4.0 1.4 Sludge Specific Gravity 1.020 1.105 1.075 Estimate: a. the mass of solids to be treated (pounds dry weight per day), b. the volume of sludge to be treated (gallons per day), and c. the specific gravity of the solids....
