W2A: Ion Exchange Technology and Practical Operating Practices (repeat from Sunday)
Wayne Bernahl, W. Bernahl Enterprises, Elmhurst, IL

Ion exchange technology is not new yet most industrial ion exchange systems do not operate at top efficiency. Ion exchange technology is often not well understood by operating personnel.


W7A: The Wonderful World of Reverse Osmosis – 2023 (repeat from Wednesday)
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.


W18: Wet FGD Chemistry and Operational Impacts on Wastewater Quality Discharge
Bryan Hansen, P.E., Burns & McDonnell, Centennial, CO

This workshop will provide an overview of wet FGD chemistry and operating factors that will affect the wastewater quality. The various subsystems of the wet FGD system will be discussed including reagent handling, reagent preparation, absorber internals, recycle slurry, slurry spray headers, mist eliminators, primary dewatering, secondary dewatering, and wastewater treatment. The workshop will discuss the operational chemistry involved in removal of SO2 from the flue gas and highlight how operating parameters like pH, conductivity, ORP, and other issues affect the overall process. The workshop will address how operation of the wet FGD system can affect the quality of the wastewater being discharged. The workshop will provide troubleshooting tips for the operation of the wet FGD system.


W19: Biological Unit Processes: Carbon, Nitrogen, and Metal(oid) Treatment
Daniel Carey, Worley, Charlotte, NC

Biological treatment is the core unit process for wastewater treatment for many industries including mining, power, chemical production, pharmaceutical production, refining, and others. In this workshop, wastewater treatment concepts will be distilled to core first principals of chemistry, microbiology, and bioprocess engineering.

The course will cover fundamentals, design criteria, and operating philosophies of biological systems. Attendees will learn this complex topic through a focus on target constituents for removal. The workshop will be organized into three modules. The first module with focus on carbon (COD) removal and aerobic biological treatment. The second module will focus on nitrogen removal with an additional focus on anoxic biological treatment. The final module will present other relevant applications such as selenium removal.

By the end of the workshop, participants will have an understanding of the biological aspects of wastewater treatment, including, the advantages and limitations of biological processes, the operational challenges associated with maintaining and optimizing biological treatment, and the emerging trends and technologies in biological wastewater treatment.

W20: Water Treatment for Industrial Boiler Systems
Ray Titsing, Veolia Water Technologies & Solutions, Horsham, PA

The objective of the workshop is to provide a broad understanding of the water related problems that can be encountered in industrial boiler steam systems and the monitoring and treatment options that can be used to maintain reliable, efficient operation.

Participants will learn:

  • How deaerators work and common errors that cause boiler feedline corrosion problems.
  • Causes of downtime corrosion and steps to control it.
  • The causes of flow accelerated corrosion and its control.
  • The causes and control of boiler deposits and corrosion.
  • The problems caused by steam contamination and steps to avoid these problems.
  • The causes of condensate system corrosion and  treatment technologies to control corrosion.
