Physicochemical Treatment Processes

Edited by Lawrence K. Wang, Yung-Tse Hung, and Nazih K. Shamma

This book is intended to be a critical survey of both the principles and practices involved in water pollution control, potable water treatment, water reuse, and sludge treatment. The author or authors of each chapter discuss the performance, potential, and limitations of each major physicochemical treatment process in detail-including physical and chemical theory, the applications, the design procedures, examples, references and cost data-as a basis for intelligent planning and realization of treatment systems.

This book has been designed to serve as a basic physicochemical treatment text as well as a comprehensive reference book to be used by students, engineers designing water and wastewater treatment systems, and those conducting research.

The following list of the book’s chapter titles also includes some of the topics covered in each section:

* Screening and Comminution-the function of screens and comminutors, cleaning methods, engineering specifications, engineering design, and design samples.

* Flow Equalization and Neutralization-mixing and aeration requirements, pH, buffer capacity, hardness, acidity and alkalinity, common neutralization treatments, pH neutralization practices, and designing a neutralization system.

* Mixing-mixing efficiency, fluid shear, mixing processes and equipment, and design of mixing facilities.

* Coagulation and Flocculation-applications of coagulation, properties of colloidal systems, colloidal structure and stability, influencing factors, coagulants, coagulation control, chemical feeding, mixing, rapid mix, flocculation, and design examples.

* Chemical Precipitation-process types, chemical precipitation principles and kinetics, design considerations, process applications, and process evaluation.

* Recarbonation and Softening-softening and recarbonation process chemistry, lime/soda ash softening process, water stabilization, and process design.

* Chemical Oxidation-dissolved oxygen and the concept of oxidation, oxygenated reagent systems, transition-metal ion oxidation systems, and recent developments in chemical oxidation.

* Halogenation and Disinfection-the chemistry of halogenation, disinfection with halogens, recent developments in halogenation technology, and design and application examples.

* Ozonation-applications of ozone, process and design considerations, and costs of ozonation systems.

* Electrolysis-organics and suspended solids removal, disinfection, and removal of phosphate, ammonium, cyanide, and metals.

* Sedimentation-sedimentation tanks in water and wastewater treatment, grit chambers, gravity thickening in sludge treatment, and costs.

* Dissolved Air Flotation-theory and design, chemical treatment, sampling and monitoring, emergency operating procedures, and recent developments.

* Gravity Filtration-mathematical models, design considerations, and applications.

* Polymeric Adsorption and Regenerant Distillation-applications and evaluation, adsorbents, design considerations, and distillation.

* Granular Activated Carbon Adsorption-adsorption column models, regeneration, economics, design examples, and recent developments.

* Physicochemical Treatment Processes for Water Reuse- conventional physicochemical treatment processes, applications in wastewater treatment and reuse, and applications of membrane processes.

* Introduction to Sludge Treatmentconditioning processes, dewatering processes, stabilization processes, and thermal processes.
