Description

This volume gives an overview of the wide spectrum of nitrogen removal processes available today. Part A gives a brief outline of nitrogen pollution sources, the global nitrogen cycle and the treatment methods; part B presents details of all biological methods for nitrogen removal; and part C describes the physico-chemical nitrogen removal methods. Design examples relating to parts B and C are given in appendices.

Design equations are given in the text, but more emphasis has been placed on the profound understanding of the biological and chemical processes and the basic factors that influence these. Parameters and regression equations for a quantitive description of these factors and their influence on the key processes are presented in several tables. This feature makes the volume a very useful handbook; it will be of great value to those environmentalists who require a record of the available nitrogen removal methods from both biological and chemical viewpoints.
