Opis

A guide to the microbiological and technical aspects of bulking and foaming control. It stresses practical control measures based on kinetic and metabolic selection theories and supported by case histories. It includes topics such as: biochemical processes in wastewater treatment, evaluation of separation problems, and system design.
