WEF is moving the Forum on Particles and Colloids, initially scheduled for July 2021, to January 2022.  This event brings together a small group of water professionals worldwide to foster far-reaching and in-depth discussions on a specific topic of interest in an in-person format. 



WEF Forum 2022: Particles and Colloids

The Next Frontier in Intensifying Water Resource Recovery

January 10-12, 2022

Fort Lauderdale, Florida


The WEF Forum brings a small group of about 150 water professionals together to foster far-reaching and in-depth discussions on a specific topic of interest.  It is a single track, two and a half-day experience that includes group meals and evening activities where discussions around the event topic continue, leading to impactful conclusions and developments.

Attendees of the Forum 2022 will take a deep dive into the world of particles and colloids (P&Cs) to understand how best to apply modern P&C science to engineered water systems, identifying new areas for exploration. This Forum will feature short and highly technical presentations providing context on the following session topics:

  • Session 1: P&Cs Beyond the Standard Turbidity and TSS
  • Session 2: Particle Type and Particle Properties
  • Session 3: P&C Processes
  • Session 4: Methods for Characterization and Monitoring P&Cs

Facilitated discussions around these topics will advance the overall knowledge of the P&C industry, leading to impactful new innovative ideas and developments.

The official Forum hashtag is #WEFForum. Be sure to use it in your social media posts, and RSVP to the Facebook event!

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.
