Environmental effects associated with various ocean disposal practices are determined to a large extent by the fate of waste particles. The importance of coagulation on particle deposition rates has previously been reported in the literature. Additional study, however, is needed in developing a simple analytical framework for predicting particle removal for field applications. The objective of this is twofold: first, to present a simplified kinetic expression for the coagulation/settling of particles that is applicable to field conditions; and second, to show preliminary calculations for the case of sewage discharge.
