W-6: Biological Wastewater Treatment – A Chemical Engineering Perspective on Biological Processes
Kyle Stern, Kiewit Engineering Inc., Lenexa, KS

Objective is for attendees to get an introduction and foundational understanding of biological processes for treating carbonaceous waste, as well as macronutrients such as nitrogen and phosphorus. As a chemical engineer primarily, this workshop will come from the perspective of the underlying foundational reactions and kinetics to gain process understanding.
We build this understanding by looking at different industrial applications for biological treatment and how these type of systems can tie into process objectives.


W-7: The Wonderful World of Reverse Osmosis – 2023
Jane Kucera Nalco Water, an Ecolab Company, Plainfield, IL and Lyndsey Wiles, ZwitterCo, Inc., Los Osos, CA

Reverse osmosis (RO) has become a very popular and useful water demineralization tool, for both water and wastewater applications. Understanding the fundamentals of RO, particularly as applications become more challenging in the environment of reduce, reuse, and recycle, is critical to optimal operations.
However, during the growth or RO applications, some of the basics have been lost in shuffle. And many times professionals and operators familiar with other demineralization technologies are now faced with operating RO systems with little or no training. Hence, this Workshop covers the basics and best practices of RO technology, from sound design to proper operating techniques. Fouling and concentration polarization, data collection and normalization, pretreatment (including membrane filtration), cleaning, and storage are just some of the topics included in this Workshop. This Workshop is intended for all who need to understand the essentials of RO to help obtain optimal performance of this technology.


W-8: PFAS 101 – Practical Considerations
John Peichel, Veolia Water Technologies & Solutions, Minnetonka, MN

Attendees will get an introduction to PFAS, chemistry regulations, treatment solutions, and disposal both current technology and new developments. Hands on exercises will assist in learning the practical considerations when dealing with PFAS in industrial water treatment.


W-9: Design Optimization for Industrial Water and Wastewater Systems
TBD, DuPont Water Solutions and Erik Desormeaux, Energy Recovery, Inc.

The objective of the workshop is to provide an in-depth understanding of the key principles and practices involved in optimizing the design of membrane based industrial water and wastewater treatment systems. This will include example applications and case studies for lithium, water reuse, green hydrogen and high recovery applications.

The workshop will begin with an overview of the key components of industrial treatment systems, including membranes and energy recovery devices (ERDs), different membrane and ERD configurations, and available products. Participants will learn how to select the right technology for a given application and the key design principles involved to optimize performance.

In addition, the workshop will provide an overview of the various modeling and simulation tools available for optimizing the design of reverse osmosis systems and how to use these tools to model system performance under different operating conditions. By the end of the workshop, participants will have a comprehensive understanding of the key principles and practices involved in optimizing the design of membrane industrial water and wastewater reverse osmosis treatment systems.

After the presentations, participants will have the opportunity to engage in hands-on learning and knowledge sharing during our complementary networking drinks reception.


W-10: Industrial Water Reuse – Lessons Learned & New Technologies
Ed Greenwood, P.Eng. BCEE, WSP, Barrie, Ontario, Canada

The primary objective of this workshop is knowledge transfer. It is aimed at those vested in developing the next generation industrial water reuse plant. Several workshop facilitators will objectively compare competing strategies to treat and recover industrial wastewater for reuse.

With many reuse plants approaching 10 or 15 years of operation, the field of Industrial Water Reuse is maturing.  Some reuse strategies have proven to be reliable and cost-effective but some have not. This workshop will explore the reasons why and address the common issues facing water reuse.

Topics will include:

  • Navigating the challenging and changing water treatment technology landscape – an unbiased comparison of popular treatment technologies (i.e. Clarifiers, MMF, MF, UF, NF, GAC, RO, CCRO, CFRO, HPRO, ED, Chlorine, Ozone, AOP, UV)
  • Common problems (design issues and performance issues)
  • Emerging membrane technologies and opportunities
  • Comparing new technologies for brine concentration/minimization
  • Optimizing cost and reliability
  • Case Studies (success stories and cautionary tales)

Four workshop facilitators will encourage interactive discussions on case studies to unravel lessons learned. Participants will leave the workshop with a broad understanding of the industrial water reuse landscape and how they might apply some of the more popular reuse strategies to develop the next generation water reuse plant.
