Abstract: Particle size distributions in wastewater can be used to monitor and model the transformations that occur during wastewater treatment processes. Typical size distributions of organic contaminants in wastewater are presented and the importance of particle size for wastewater treatment is discussed. Experimental evidence for the significance of kinetic limitations for biological degradation of particulate matter is presented and discussed. Concepts of particle size management are introduced and some applications for biological wastewater treatment are presented. The ultimate benefit of particle size management is the development of an improved rationale for the selection, design and evaluation of wastewater treatment systems. (Author abstract. )
