1 ADVANCED TECHNOLOGIES FOR THE TREATMENT OF CONTAMINATED WATERS: Rotating Biological Contactors and Fluidized Beds Academic Agreement UNALMED-RYERSON UNIVERSITY Manuel Alvarez Cuenca, Ph.D., P. Eng., Professor Director of the Laboratory of Water Treatment Technologies Department of Chemical Engineering, Ryerson University, Toronto, Canada Universidad Nacional de Colombia, Medellin Facultad de Minas, Medellin, Colombia September 23-25,

2 Professor, Manuel Alvarez Cuenca, Ph.D., P.Eng. Dr. Cuenca is a professor of Chemical Engineering and Director of the Laboratory of Water Treatment Technologies of Ryerson University (Toronto) since He has over 20 years of industrial experience with large corporations (ENDESA, ESSO Ontario Hydro). He is an environmental consultant with Ecotechnos Inc. in Toronto. Manuel is the author of numerous publications, three US patents (one pending), two Canadian patents and a book on Fluidized Bed Technology. He is an international speaker and organizer of many conferences on water/wastewater treatment. He is an adjunct professor with the University of Waterloo, the University of Guelph, and the Universidad Nacional de Colombia. His areas of expertise include design and performance evaluation of advanced reactors including Rotating Biological Contactors, Fluidized Bed Bioreactors, and Nutrient Removal (Nitrogen and Phosphorous removal) from industrial and municipal wastewater. He has won international awards in the area of design of wastewater treatment plants. Page1

3 TABLE OF CONTENTS September 23, DAY 1, (9:00AM-12:00 PM) The Seminar is to be verbally delivered in Spanish with slides in English. However it could be delivered entirely in English if the audience feels more comfortable in English. 1. Objective of this Seminar a. To offer a perspective of the two most effectives technologies in Secondary Wastewater Treatment. b. To explain the Academic Agreement Unalmed-Ryerson University (Toronto, Canada) : Opportunities for Graduate Studies in Water Engineering c. The Water Treatment Technologies in Ryerson University 2. The Global Water Crisis: Demographics, Mismanagement, and Greed. The new pollutants; nutrients, endocrine disruptors, other pharmaceutical and complex chemicals. New opportunities in water treatment: Power generation(fuel cells), metals recovery (Phosphorous) 3. Trends in Water Engineering. The next decades. This course is not about cement and concrete but about effective processes and reactors!! 4. "Contaminated Water" or "Wastewater"? Domestic and Industrial Contaminated Water 5. Equalization, Pre-treatment, Primary Treatment, Secondary Treatment, Tertiary Treatment, Energy Recovery. 6. Effective Technologies in Secondary Treatment: RBC, Fluidized Beds, Activated Sludge 7. Rudimentary Technologies in Secondary Treatment: Trickling Filters, Septic tanks, and Lagoons. (I) Rotating Biological Contactors (RBCs) are probably the most effective of the commercial wastewater treatment technologies,especially for medium and small flowrates. Unfortunately, commercial success does not always reflect technological success as marketing plays a central role in commercial activity and dissemination of

4 information is expensive. Furthermore, universities or colleges seldom provide an introductory course on this discipline. Thus, environmental engineers and consultants are not familiar with RBC processes and technologies. This brief seminar introduces the participants to RBC technology. For the sake of a better understanding, examples are drawn from all prototypes of RBCs. 1. Historical glance. 2. Fixed film technologies are more effective 3. Example of large and small RBC Plants 4. Typical RBC Plant: Treatment Phases a. Equalization b. FOG and SS Removal 5. Design Basis of RBCs: The media (discs) is critical for a successful performance 6. RBC Plant Performance: How to select the technology to design a Contaminated Water Treatment Plant (CWTP). The MAC diagram September 24, DAY 2, (9:00 AM-12 PM) (II) 7.Components of an RBC a. The Shaft b. The Media c. The Load Cell d. Air Diffusers e. What about a membrane unit? (III) 8. Factors affecting RBC Performance 9. Flow Distribution and Distribution of Stages in RBCs 10. BOD 5 and NH 3 Removal 11. Conclusions Page1

5 September 25 (DAY 3, 9:00 AM) (I) FLUIDIZED BEDS Fluidization, in any of its multiple forms, is responsible for a vast industrial activity whose worldwide applications and economic impact can be expressed in hundred of billions of dollars. The application of this technology extends to the manufacturing of essential commodities like liquid fuels, and electric power, to the production of pharmaceuticals and foods, and the treatment of solid and liquid wastes in environmental engineering. 1. The Phenomenon of Fluidization 2. Selected Industrial Applications 3. Fundamentals 4. Introduction to Pneumatic Conveying 5. Heat and Mass Transfer in Fluid Beds 6. Chemical Reactions in Fluidized Beds (II) FLUIDIZED BEDS 7. Type of Fluid Bed Reactors: Atmospheric, Pressurized and Circulating 8. Particle Collection Equipment 9. Design Parameter in Fluidized Beds 10. Applications in the Chemical Process Industries, Electric Power Generation, Oil Refining, Coal Gasification, Fermentation, and Wastewater Treatment CONCLUSION OF THE SEMINAR Page2
