Electrodeionization (EDI) is a hybrid of two well-known processes, ion-exchange deionization (IX) and electrodialysis (ED). It was developed to allow the production of deionized water without the use of the hazardous acid and caustic that is required to regenerate ion exchange resins. EDI is now over 30 years old and is used extensively in many industries, especially in the production of deionized water for pharmaceutical formulations, power generation and manufacture of microelectronics/semiconductor devices. It is usually employed as a polishing demineralization step with reverse osmosis (RO) upstream as the roughing demineralizer.
This workshop will start by reviewing the principles of the EDI process, how it differs from IX, how EDI modules are constructed, and EDI feed water requirements. It will then focus on practical aspects of EDI system design, operation, maintenance and troubleshooting. This is an introductory course that requires no prior exposure to electrodeionization or electrodialysis. Some prior knowledge of basic water chemistry will be helpful.
W-13: Concentrate Management for Industrial Desalination
John Korpiel, 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
W-14: Industrial Sedimentation Principles, Practices and Hands-on Experience
Harley Schreiber, WesTech Engineering, Salt Lake City, UT
For many people, sedimentation including clarification and thickening is somewhat of a black-box process. Because of the wide array of process variables; sizing, troubleshooting and optimization of sedimentation equipment can be difficult. This workshop is designed for owners, consulting engineers, plant process engineers and plant operators who could benefit from a deeper understanding and application of sedimentation principles. In this course, fundamental principles of sedimentation are discussed and demonstrated in both live and simulated scenarios. This hands-on experience will solidify understanding of the principles and facilitate their application in specifying and operating clarifiers, thickeners, solids contact clarifiers, settlers, ballasted floc units and many other types of sedimentation equipment. At the end of this course the participant will have a better understanding of settling types, coagulation, flocculation, solids contacting, testing, and troubleshooting. There will be opportunities to discuss specific challenges you might have with a panel of experienced engineers and educators who can help you better understand your sedimentation process needs.

W-17: Arsenic & Selenium Removal
John Schubert, HDR Inc., Sarasota, FL
Changes in regulations in the coal-fired power industry and existing standards in the mining industry are but two examples of increased regulatory attention on arsenic and selenium. These ions have not been the focus of wastewater treatment historically. Many new technologies are being promoted for use in arsenic and selenium treatment. However, it is difficult to assess the real potential of treatment technologies to cost-effectively achieve the desired goals without substantial background in this area.
This course provides a sound basis for those concerned with arsenic, selenium or both to make sound decisions about treatment options. The course reviews the chemistry, sources and regulatory basis for these elements. The various treatment approaches currently available, included physical/chemical, biological, membrane, and adsorption processes, are thoroughly discussed. The attendee can expect to gain a better understanding of the sources of arsenic and selenium in the environment, their chemistry and the approaches available to them for treatment of contaminated water.
Time: 1:00 – 5:00 PM
