“Best of IWC”

Webinar Series

The Best of IWC Webinar Series is a great way to preview the high quality technical content presented at the International Water Conference®.

  • Attendees can earn 1 PDH credit from the comfort of their own computer.
  • It is FREE to attend, but registration is required for pdh certification.  Multiple viewers on one computer will be required to sign in on the required form distributed at the webinar.

Note: Individual NY P.E.’s requesting the 1 PDH must sign into the webinar via the link provided when registered and are also required to sign a login sheet after completion of the webinar. NY P.E.’s attending the webinar as a group require only one person to register for the webinar. That person is the room moderator for the group and must sign into the webinar via the link provided when registered. Each attendee in the group will be required to sign in and out on the login sheet. The times and signatures are verified by the room moderator.

New Webinars coming soon……


Past Webinars

Topic: Mining
September, 2018

Shannon Brown, John Pugh, and Jason Maughan, Monsanto, Creve Coeur, MO; Karen Budgell, Golder Associates, Lakewood, CO
Title: “Review and Evaluation of Water Treatment Technologies for Removal of Selenium and Other Constituents of Concern in an Industrial Application”

Increasingly stringent water quality regulations lead industry to seek cost effective, reliable, and robust water treatment technologies to achieve specific needs of each manufacturing site. A technology screening was conducted based on available technologies and water quality requirements for one industrial site. Bioreactor and reverse osmosis pilot testing is underway targeting removal of selenium and other constituents of concern. Characterization, technology screening, and pilot testing results from one industrial process water are discussed herein.

 Joseph Tamburini, P.E. and Lauren Lundquist, Tetra Tech, Inc., Denver, CO
Title: “Considerations for Selenium Treatment of Mine-Impacted Waters”

Mine-impacted water occurs as surface run-off and ground water seepage contacts waste rock from previous mining operations, and may contain selenium from waste rock and nitrate from residual blasting residue. These dissolved constituents are difficult to remove from mine-impacted water via conventional chemical treatment approaches. This paper will discuss important criteria to consider selecting the best technology for treatment, and strengths and weaknesses of different technologies.


Topic: Wastewater Membranes
August, 2018

Ed Greenwood, P.Eng., Wood, Cambridge, ON, Canada; John Christiansen, P.E., Wood, Houston, TX; Dan Kwiecinski, P.E., Wood, Albuquerque, NM; Scott Denton, The HollyFrontier Companies, Artesia, NM; Robert Kimball, Wood, Denver, CO
Title: “A Unique High Recovery Secondary RO to Resolve Refinery Source Water and Brine Disposal Issues”

Amec Foster Wheeler designed and constructed a unique high recovery Secondary RO system at a Refinery in New Mexico to resolve source water and wastewater disposal limitations. The new system is directly coupled to the Primary RO System and operates beyond the solubility limits for Silica and Calcium Sulfate by using a unique high recovery three stage arrays with both permeate and concentrate recycle loops to optimize performance.

James Peters, PPG Industries, Monroeville, PA
Title: “Use of a Novel Membrane Technology to Treat Industrial Process and Waste Waters”

This paper will review a novel composite single layer membrane that provides high flux, excellent separation capabilities and durability. The presentation will review intrinsic membrane properties that create a durable, fouling resistant and high flux membrane. Lab scale and pilot field tests will be reviewed in a variety of industries. The case studies will focus on how the new filtration technology met real world customer needs allowing scale-up to larger field tests or commercial units.


Topic: Industrial Water Reuse
June, 2018

Thomas Orth, Technoform Kunststoffprofile GmbH, Lohfelden, Germany
Title: “Conductive Plastic Evaporator Tubes – New Chances for the Water Business”

Evaporator tubes are one of the basic components in thermal water treatment applications. Until today, these tubes are made of metal. But now plastics become more and more attractive as heat exchanger materials, especially in harsh chemical environments. Unfortunately, their field of application is limited due to their thermal and mechanical properties. New polymer composites overcome these drawbacks and show good mechanical properties together with excellent thermal performance and outstanding fouling resistance.

Yakup Nurdogan, Ph.D., P.E., Bechtel, Pueblo, CO
Title: “Start-up of Zero Liquid Discharge System to Recycle and Reuse Biotreated Effluent”

The Pueblo Chemical Agent-Destruction Pilot Plant is constructed to destroy mustard agent by hot water hydrolysis followed by caustic neutralization. A zero-liquid discharge (ZLD) system was constructed to recover the water from the biotreated hydrolysate. The ZLD system includes an evaporator, crystallizer, and dewatering system to remove dissolved and suspended solids from biotreated effluent. The ZLD system was started in July 2016. More than 80% of the water is recovered and recycled to be reused by the agent hydrolysers, cooling towers, reverse osmosis units, biotreatment system, and offgas treatment system scrubber.


Topic: CCR
When: Wednesday, July, 2018

Chloe Grabowski, HDR, Missoula, MT
Title: “ELG and CCR Rule Implementation: Treatment and Handling of General Plant Wastewater Flows”

This paper will focus on a planning study conducted at a large coal fired power generating facility in North America for the purpose of developing design requirements for the treatment and handling of general plant wastewater (GPWW) flows through the use of settling basins. Following implementation of the CCR rule and revised ELGs it will be necessary to handle and treat GPWW flows separately.

Jason Eichenberger and Samantha Tewell, Burns & McDonnell, Kansas City, MO
Title: “What Happens to My non-CCR Streams?”

Many existing surface impoundments receive non-CCR streams; however, new process ponds or other treatment methods may be required at many power plants for future CCR compliance. After removal of CCR flows, the remaining flows will make a large impact on constituent levels, potentially causing them to exceed the anticipated future permit limits. This paper highlights several factors for process pond and tank-based treatment designs at confidential plant sites and presents lessons learned and sampling recommendations.
