Process Designs in Environmental Pollution Control

Environmental pollution occurs as a result of uncontrolled discharge of waste materials, which are released as a result of human activities and which are not evaluated, to the receiving environment such as air, water and soil, and causes significant changes in the ecological balance of nature. The resulting global environmental problems such as climate change, desertification, loss of biodiversity, deforestation, destruction of the ozone layer endanger the sustainability of the environment, and pose significant threats to the health, survival, food and water resources of humans and other living species.
Maintaining a healthy life is only possible with a healthy environment. For a healthy environment, the natural balance, that is, the protection of the ecosystem, is only possible with the control of environmental pollution.
This book has been prepared in order to give the necessary processes and design principles for the treatment of wastes that cause air, water and soil pollution as a result of production and consumption activities, and solutions of problems and design examples are given for a better understanding of treatment/disposal process designs.
In the first part of the book, environmental problems are briefly introduced; In the second part, as air pollution control processes, the designs of cyclones, wet scrubbers, bag filters and electrostatic filters in the retention of solid particles, physical processes such as filled absorber, adsorption, membrane in the treatment of dangerous substances in flue gases and the processes involving reactions are examined, sulfur dioxide; Examples of the design of control processes for gases that cause important environmental problems such as nitrogen oxides and carbon dioxide are given.
In the third chapter, water pollution and control processes are discussed and the physical; chemical and biological treatment processes were investigated. In this section, exemplary designs have been made by adsorption, air stripping and water purification with ion exchangers; in chemical treatment processes, precipitation, electrochemical treatment, wet air oxidation, advanced oxidation processes are examined and sample problems are given.
The processes applied in the biological treatment of wastewater are given and the design of the activated sludge treatment system is made.
In the fourth chapter, which deals with soil pollution, physical bioremediation and chemical treatment processes are examined and sample problems are included.
In the last part of the book, solid wastes and their management are examined and re-evaluation of solid wastes; their regular storage; composting; biogas production; burning (incineration); Information about pyrolysis and gasification processes are presented and sample designs are given.
In conclusion, this book has been prepared as a useful resource for undergraduate and graduate students and engineers interested in environmental pollution control.
