E-raamat: Biological Wastewater Treatment Processes: Mass and Heat Balances

"The book describes how to use kinetic models based on the concept of biomass growth and growth stoichiometry to simulate, design and optimize biological wastewater treatment processes. The general approach used in the book is to write rate equations forthe various processes occurring and coupling them with mass balances specific for each process. The resulting system of non linear equations or of differential equation is then solved using Microsoft Excel. By varying the values of the design variables, the process is designed, simulated and optimized. In addition to the traditional design variables such as reactor volume, substrate removal, excess sludge production, particular focus is given in the book to pH calculation, which is particularly importantfor nitrogen removal and anaerobic processes. The book also shows how this modeling methodology can be applied to specific case studies reported in the literature."--

In our environmentally-conscious present, effective wastewater treatment processes consistently play a major role in determining the continued health and prosperity of global communities, affecting larger matters of environmental reform, governmental administration, and models of public safety. To the ever-expanding field of wastewater treatment theory, Dr. Davide Dionisi contributes this insightful guide examining the use of mass and heat balances to simulate and design biological wastewater treatment processes. All these processes and more are covered in Dr. Dionisi’s Biological Wastewater Treatment Processes: Mass and Heat Balances, which carefully examines modern methods of wastewater cleaning through activated sludge processes for carbon and nitrogen removal, anaerobic digestion, sequencing batch reactors and attached growth processes. Dr. Dionisi provides concise models and meticulously detailed case studies that effectively describe the principles of stoichiometry and the kinetics of biological and non-biological processes occurring in biological wastewater treatment processes. This detailed resource acts as a step-by-step guide to writing the mass and heat balances appropriate for any process configurations and showing their use to calculate the reactor volume, the flow rates of all streams, aeration requirements, sludge production, the size of the settling tank, and the pH. In addition, this book provides:

- Detailed procedures to write the stoichiometry and kinetics of biological processes;

- Detailed guide to pH calculations in biological processes;

- Design and simulation of aerobic, anoxic and anaerobic processes;

- Numerous worked examples and problems, all solved using Microsoft Excel.
