Workshops
Thursday, November 7; 8:00 AM – 12:00 PM
W-01A: Water Treatment 101 (repeat from Sunday)
Dennis McBride, Burns & McDonnell, Kansas City, MO
This workshop is a great introductory course covering many of the basic concepts of industrial water treatment. It will address unit operations (clarification, filtration, lime/soda ash softening, iron and manganese removal, membrane filters, and roughing demineralizers) used in water preparation for industry with emphasis on power, chemical industry, and refineries. It includes treatment of cooling water systems as well as boiler water makeup. Wastewater generated by these unit operations and their treatment and disposal will be discussed. Basic water chemistry requirements for low, medium, and high pressure boilers will also be discussed.
W-12: Concentrate Management for Industrial Desalination
John Korpiel, P.E., Veolia Water Technologies, Wexford, PA
This workshop will provide an overview of the options for managing the concentrate generated from industrial desalination processes and their associated challenges. The workshop is intended for engineers, technologists, managers, and operators who want to gain a better understanding of concentrate management, but will also serve as a refresher for those who already have experience in this area.
As fresh water sources become increasingly scarce throughout the world, industries are becoming more reliant on desalination technologies to operate in a reliable and sustainable manner. Desalination technologies are essential in industrial applications for treating challenging water and wastewater sources to generate a quality of water that is suitable for process needs and for meeting regulatory discharge water quality requirements. However, all desalination technologies generate a brine byproduct, also referred to as the concentrate or reject stream. Typically, brine has undesirable characteristics such as high salinity, high scaling and fouling potential, is corrosive, and contains concentrated contaminants and/or residual chemicals. As a result, brine is challenging and costly to concentrate, handle, treat, and dispose, and can be harmful to the environment, if not managed properly. A major challenge of applying any desalination technology in a cost-effective and sustainable manner is implementing an appropriate concentrate management strategy.
The following topics will be discussed in the workshop:
• Overview of brine management options available for disposal and beneficial reuse, including surface water discharge, deep well injection, evaporation ponds, land application, and zero liquid discharge (ZLD)
• Strategies for brine minimization using conventional and proprietary membrane-based technologies for minimum liquid discharge (MLD) applications
• Thermal technologies for reduced liquid discharge (RLD) or ZLD applications; the latter of which eliminates the brine stream, generating a solid byproduct that is suitable for disposal in a landfill or for beneficial reuse.
• The benefits, issues, and limitations of each of the brine management options and technologies
• Examples of integrated MLD and ZLD systems will be presented
• Emerging technologies for brine minimization
• Factors to consider for evaluating the options and selecting the appropriate concentrate management approach for a given application.
W-13: Concentrate Management for Industrial Desalination
John Korpiel, P.E., Veolia Water Technologies, Wexford, PA
This workshop will provide an overview of wet FGD chemistry and operating factors that will affect the wastewater quality.
W-14: 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.
W-15: Trouble Shooting IEX Equipment
Donald Downey, Purolite, an Ecolab Company, Paris, ON, Canada
I plan to impart trouble shooting skills to aid demineralizer plant operators and engineer skills necessary to trouble shoot and solve equipment or media problems.
