Time: 1:00-5:00 PM

W-06: Ion Exchange Technology and Practical Operating Practices
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.
 

W-07: 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 hours as described below.
By the end of the workshop, participants will understand the biological aspects of wastewater treatment, including, the advantages/limitations of biological processes, the operational challenges associated with maintaining/optimizing biological treatment, the emerging trends in biological wastewater treatment, and methods for preliminary sizing of biological treatment systems.
 

W-08: Holistic Approach to Water Treatment
Jasbir Gill, Ph.D., Water Energy Solutions Inc., Naperville, IL

Teaching the Art and Science of water treatment in light of balancing water saving, energy consumption , and its impact on environment.
Some commercial water treaters focus on just water savings, either recovering water (sometimes using very intensive energy use technologies to recover waste-water) or lowering pH. How much is the actual cost in terms of dollars and environmental.
 

W-09: Wet FGD Chemistry and Operational Impacts on Wastewater Quality Discharge
Bryan Hansen, P.E., Burns & McDonnell, Kansas City, MO

This workshop will provide an overview of wet FGD chemistry and operating factors that will affect the wastewater quality.
