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-16: Leadership & Career Skills for Tomorrow’s Water Professionals
(FREE to Attend)
Jonathan Shimko, McKim & Creed, Pittsburgh, PA
This workshop will be interactive and will provide opportunities for participants to engage in useful dialogue to gain understanding and familiarity with the concepts presented. In addition to short presentations on each topic, participants will be asked to collaborate with each other on activities that provide simulations into real life situations. The goal of this workshop is to energize and equip each participant with skills and tools that can provide a lifetime of support and help change their career trajectory for the better. Additionally, participants will have the opportunity to interact with water industry experts and hear their stories and get their advice.
- Overview of the Water Industry
- Ten “Soft Skills” that can Lead to Success in Life and Your Career
- Essential Communication Skills
- How to Interact with a “Customer”
- Diversity & Inclusion in the Water Industry
- How to Stand out Amongst our Peers
- Maintaining a Work-Life Balance
- Industry Panel Discussion and Q/A
Time: 1:00 – 5:00 PM
W-03A: Ion Exchange Technology and Practical Operating Practices
Wayne Bernahl, W. Bernahl Enterprises, Elmhurst, IL – (repeated from Sunday)
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.
The participant of this workshop will:
- Better understand basic ion exchange equipment, operations, and resins used for water treatment operations
- Better understand what can go wrong with ion exchange systems
- Develop a logical troubleshooting approach to discover and correct operating problems.
W-18: Coagulation and Flocculation: Theory, Practice, and Examples
Ken Martins, Stantec, Reno, NV
The workshop has four major objectives; (1) Provide a sound basis of theoretical understanding – The discussion will be suitable for both engineers and operating staff and will provide a solid basis of understanding applicable to virtually any industry. Students will be introduced the concept of colloids and colloidal stability, the double layer theory, the concept of zeta potential and energy barriers and various molecular forces, such as van der Waals and Brownian motion, (2) Provide a clear summary of typical industry practices – The students will understand the differences between inorganic and organic coagulants and flocculants (i.e., charge type, molecular weight, percent charge, physical form), typical industry practices for makedown and application of coagulants and flocculants, and design features for coagulation and flocculation systems (i.e., tank features, mixer energy, shear, and tip speed, etc.), (3) Illustrate Common Industrial Applications – Students will be introduced to a broad spectrum of water and wastewater applications across the major heavy industries. The course will discuss applications such as common clarification and filtration, lime soda softening, biofloc, biopolymers and augmentation with flocculants, oily water treatment, and dewatering applications. The students will understand realistic expectations for the performance impacts of coagulants and flocculants as applied for varied applications and industries.
