In the water industry, particles and colloids (P&Cs) are everywhere: a resource to be recovered at preliminary/primary stage (front), a driver of reaction rates for the secondary treatment (middle), and a liability to be removed in the final effluent for high-end water reuse (end). The real science and engineering of P&Cs is often oversimplified and, in most cases, poorly understood. Kinetic modeling parameters to account for particle behavior like P&C surface chemistries, size, density and composition are mostly neglected, and current methods for characterizing P&C are rudimentary at best.
The WEF Forum seeks to advance our understanding of how best to apply modern P&C science to engineered water systems as well as identify new areas for exploration. This forum will consider the broad problems and opportunities of P&Cs ranging from physical and chemical to biological reactions associated with P&C. In addition, the program will be focused on the most interesting and exciting P&C science and research innovation opportunities for treatment process design, operation and intensification.
