1. Three separation unit operations (trommel screen, magnet, air classifier) are used to separate paper, ferrous, and glass. The fraction of each material being rejected is:
| Material | Feed (tons/hour) |
Trommel Screen Rejection Fraction |
Magnet Rejection Fraction |
Air Classifier Rejection Fraction |
| Paper | 40 | 0.9 | 0.9 | 0.1 |
| Ferrous | 10 | 0.5 | 0.05 | 0.95 |
| Glass | 10 | 0.1 | 1 | 0.5 |
Determine the appropriate order and combination of the units to achieve the highest recovery (you may use one, two, or three of the unit operations)

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
