Abstract: The premise that the morphology of deposits formed from colloids, aerosols, and other particulate materials can be predicted from their transport properties and surface chemistries is explored. Universality classes that group the conditions of particles in suspension to the structure of a deposit composed of a large number of particles are considered in the context of their importance in natural and engineered systems encountered in environmental engineering. Evidence for one such “transport-morphology link” is presented, and the implications of this linkage in filter modeling, prediction of sediment characteristics, and membrane fouling are presented.
