Cooling Water Chemistry Innovations Support Environmental Needs: New Green Chemicals, New Non-P Treatment, and Innovative Yellow Metal Treatment Technology in Contaminated Water Reuse

IWC Rep: Michele Funk, Bechtel Corporation, Reston, VA
Session Chair: Charles Kuhfeldt, CauseWay Water Consulting and Services, LLC, Taylor Lake Village, TX
Discussion Leader: Chris Baron, ChemTreat, Newark, DE

Three presentations aid the sustainability of water use, water reuse and protection of natural resources through chemical innovation. Research continues toward the availability of naturally occurring antiscalant molecules. The first paper examines the newest developments in green (natural) antiscalants including plant extracts, biological molecules and modified natural industrial by-products. Strategies to discover these new green inhibitors, the methods to quantify their effectiveness and potential uses are discussed. In some cooling water chemistry applications interest in the removal of phosphate corrosion inhibitors is driven by discharge restrictions or concerns, as well as the potential of higher cycles and enhanced system protection through the elimination of calcium phosphate precipitation threats. The second paper introduces a new non-P corrosion inhibitor, comparing its performance in challenging applications, including sea water, to many inhibitors currently in use. The third presentation examines the problem of contaminated reuse water, microbiological control, and yellow metal corrosion control in a corrosive environment including the complication of mixed chlorine species and ammonia. Driven by a manufacturing facility cooling water application with a highly contaminated reuse water makeup source, laboratory potentiometry studies of yellow metal corrosion protection from azoles including combinations of azoles, contaminated reuse water, chlorine, monochloramine, and ammonia were used to determine the effective treatment choice.

Water Projects: Delivering a Success

IWC Rep: Brad Wolf, Berkeley Research Group, LLC, Pittsburgh, PA
Session Chair: Derek Henderson, Duke Energy, Raleigh, NC
Discussion Leader: Mike Kochevar, OLI Systems, Inc., Cedar Knolls, NJ

When implementing a water or wastewater treatment project, there are quite a few challenges that arise from design through construction. These challenges can pertain to design, schedule, cost, etc. In this session, we will review these project challenges and provide options and case studies on how to address them so that a successful project can occur.

Reverse Osmosis: The Application of a Very Important Tool

IWC Rep: Dennis McBride, Burns & McDonnell, Kansas City, MO
Session Chair: Steve McSherry, Wigen Water Technologies, Chaska, MN
Discussion Leader: David Weakley, GAI Consultants, Inc., Homestead, PA

Reverse osmosis technology is a versatile tool in the world of water treatment. It is a pre-treatment technology when used on high purity water treatment applications; a primary technology for general manufacturing applications and a post-treatment technology in waste water re-use applications. This session will examine the practical application of the technology with papers discussing membrane selection, predictive modeling software and a case study with 4 years of operating data on a waste water re-use and ZLD application.

Nitty Gritty Details of FGD Wastewater Treatment

IWC Rep: Patricia M. Scroggin, P.E., Burns & McDonnell, Chicago, IL
Session Chair: Michael Preston, Black & Veatch, Overland Park, KS
Discussion Leader: Thomas Higgins, P.E., Ph.D., Jacobs, St. Augustine, FL

The ability to predict FGD wastewater quality based on coal power plant inputs has been a type of Holy Grail since the ELG rules have been considered. Our first paper will look at the results of modelling studies attempting to predict FGD wastewater quality and the fate of particular constituents as a function of fuel and other plant inputs. Our final two papers discuss some unanticipated issues and challenges that have arisen with common FGD wastewater treatment processes as they attempt to deal with very concentrated wastewater and meet extremely low discharge requirements.
