The WEF Forums are unique in that they bring a small group of about 150 water professionals together under circumstances that foster far-reaching and in-depth discussions on a specific topic of interest.  It is a single track, two and a half day experience including group meals and evening activities where technical discussions continue. This results in a 14-hour per day experience unlike any other.   Industry experts develop a program of key areas of interest and issues and then speakers are identified to ensure the highest quality discussion possible. Formal presentations are limited with the majority of the time dedicated to facilitated discussions with prepared topic instigators. These conversations clarify the schools of thought and thus advance the overall knowledge of the industry. This format leads to impactful conclusions and developments.

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.
