DANIEL M. CICERO - NALCO COMPANY

BIO: Dan Cicero is a Senior Industry Development Manager at Nalco Company (Naperville, IL).  He is currently responsible for the fossil generation market segment in Nalco’s Power Group. Over the past 19 years, Dan has worked in a variety of sales, product marketing and new product development roles.

ABSTRACT: In 1994, EPRI published chemistry guidelines recognizing the benefits of feedwater chemistry control based on ORP.   3D TRASAR Boiler Technology controls feedwater chemistry based on ORP measured at temperature and at pressures up to 2800 psig.  This presentation will explain the benefits of using this technology in a power plant boiler system.

GREGG POPPE - DOW WATER & PROCESS SOLUTIONS

BIO: Gregg Poppe is a global application development specialist for Dow Water and Process Solutions. In this role, he is responsible for identifying new or improved products and techniques to solve water treatment problems in the industrial water and power generation markets.

Poppe joined The Dow Chemical Company in 1991, and has spent most of his career in R&D or technical service, working with technologies including reverse osmosis and nanofiltration, ion exchange, and ultrafiltration—all used in the purification of water or other aqueous streams. His experience has ranged from testing new applications for hollow-fiber microfiltration in various food processing waste streams to scaling up a new nanofiltration membrane with special rejection properties from the pilot plant to the manufacturing line. Poppe also served on special assignment to a sister plant in Denmark in 1996, and spent more than five years providing technical service to users of ion exchange resins in sweetener plants.

Until recently, Poppe was the project manager for Dow’s water treatment system design software tool, ROSA. During his six years with the program, Poppe upgraded the application making it more global to address the growing number of users in China and introduced new capabilities that allowed a designer to incorporate unique concepts such as permeate split stream and internally-staged design.

Poppe holds a degree in chemical engineering, graduating with distinction from the University of Nebraska-Lincoln, and was one of the very first Dow employees to achieve Six Sigma Black Belt certification. He is originally from Cook, Nebraska, but now resides in Prior Lake, Minnesota with his family.

Dow Water & Process Solutions has a 50 year legacy of providing innovative water and process solutions to both communities and industries alike. A differentiated business unit of The Dow Chemical Company, Dow Water & Process Solutions offers a broad portfolio of ion exchange resins, reverse osmosis membranes, ultrafiltration membranes and electrodeionization products, with strong positions in a number of major application areas, including industrial and municipal water, industrial processes, pharmaceuticals, power, residential water and wastewater and water reuse.

ABSTRACT: Achieving Lower Operating Costs and Better Water Quality with More Advanced Ion Exchange System Designs
While reverse osmosis has displaced ion exchange in the bulk demineralization step in many steam generation plants, ion exchange is still a very competitive technology choice for facilities where lower-TDS feed streams are used.  To reduce the consumption of chemicals and water during regeneration and to achieve better water quality, optimized IX system design can be used.  Chemical usage, water usage, and typical water quality that can be achieved will be compared for basic co-flow systems vs. counter-flow and packed bed systems.
