Summary: This professional textbook describes the main reasons for the growth of the different filamentous microorganisms in activated sludge solids. It presents methods for diagnosing and rectifying such problems emphasising practical control measures based upon kinetic and metabolic selection theories and practice.Continues: Manual on the causes and control of activated sludge bulking and foaming.
