This textbook introduces the elementary basics of hydrochemistry with special focus on reaction equilibria in aquatic systems and their mathematical description. Topics discussed in this textbook include: structure and properties of water, concentration measures and activities, colligative properties, basics of chemical equilibria, gas-water partitioning, acid/base reactions, precipitation/dissolution, calco-carbonic equilibrium, redox reactions, complex formation, and sorption. Examples within the text as well as problems to be solved by the reader support the acquisition of knowledge. Complete and detailed solutions to the problems are given in a separate chapter.

This book treats the theoretical fundamentals of adsorption technology for water treatment from a practical perspective. It presents all the basics needed for experimental adsorption studies as well as for process modeling and adsorber design. According to the increasing importance of micropollutants in the water cycle, particular attention is paid to their competitive adsorption in the presence of background organic matter. The current edition considers recent developments in adsorption theory and practice.

This publication provides the scientific fundamentals for understanding chemical, physical and biological processes that are used in drinking water treatment, such as filtration, coagulation, softening, deironing, demanganization and others. Written in a compact and easily accessible form, the book is focused on the objectives, the theoretical basics and the practical implementation of the treatment processes.
