Orlando to Host Power-Gen Conference

Serving the power industry for more than 20 years, Power-Gen International is the largest power industry conference and exhibition in North America, providing comprehensive coverage of trends, technologies and issues facing the generation sector. The event will be held Dec. 11-13 in Orlando, FL.

More than 1,200 companies from all sectors of the industry exhibit each year and more than 19,000 attendees come together at Power-Gen International for a horizontal look at the industry with key emphasis on new solutions and innovations for the future.

This year a half-day workshop and two conference sessions will be devoted to water topics. The workshop, entitled Power Plant Wastewater Treatment to Meet the Effluent Limitation Guidelines, is a four-hour course presented by engineers at CH2M Hill.

The course will focus on the key water management issues facing the power industry today and those that will present challenges in the near future. It will include an overview of the development of new and pending Environmental Protection Agency effluent limit guidelines and other regulations, providing an explanation of why each new regulation may be enacted, how each may affect the power industry, and a timeline of when the new legislation will go into effect.

The presentation also addresses how coal fired power plant utilities may expect to prepare for new regulation. Specific topics to be covered include dry fly ash handling, dry bottom ash handling, hydrobins for bottom ash and blowdown treatment, tank-based treatment for bottom ash and miscellaneous waters, FGD wastewater treatment, and modifying intake or outfall designs to meet permit requirements.

Proceeds from this workshop will be donated to the non-profit Water for People program, www.waterforpeople.org.

A session on Water Regulatory Compliance and Operations will offer papers that discuss various issues and related projects with respect to water/wastewater treatment and technology. Paper topics include Mercury and Trace Metals Removal Using Wet Scrubber and Wastewater Treatment; The Current and Future Use of Deep Injection Well Technology in the Power Generation Industry; and Advanced Technology for Grey and Reuse Water Treatment.

Another session will focus on complying with the Clean Water Act 316(b). Proposed 316(b) regulations will have long term impacts on the power industry. More than 670 plants will be affected. The requirements could result in facilities modifying cooling water intake structures or adding cooling towers, new screens or changing operating procedures for screens. The session will review the proposed rules and potential compliance options.

Papers to be presented include Implications of EPA's Proposed Clean Water Act 316(b) Regulations on the Power Industry; Compliance Challenges for Implementing New Cooling Water Intake Structure Regulations; Understanding the Clean Water Act §316(b) Rule for Existing Facilities; and Safe Screens: Technology-Based Fish Protection Solutions for Water Intake Structures.

In addition to the conference sessions, a variety of companies offering water treatment and management systems will be exhibiting on the show floor at Power-Gen. For more information, visit www.power-gen.com.

Condensate polishing

Graver's patented Powdex® condensate polishing system is a precoat filter demineralizer providing both suspended solids removal and ion exchange capability in a single vessel. The process uses fine particle size ion exchange resin in combination with fiber materials to form a precoat on specially designed filter septa. This precoat of ion exchange resin and fiber provides excellent filtration performance and rapid ion exchange kinetics to produce the effluent quality required to satisfy the high demands of today's utility and industrial applications.

Resin regeneration

Ovivo's Conesep® is a fully automated process for external regeneration of ion exchange resin, used in deep bed ion exchange condensate polishing. The system is designed to eliminate the problems associated with internal regeneration by transferring the ion exchange resins from the service polishing unit to separate vessels specifically designed for regeneration. When the resins are fully regenerated, they are transferred back into the service unit. The process achieves resin separation superior to conventional external regeneration systems without operator intervention, which is the key to the highest quality condensate and allows for extended runs beyond the ammonia point breakthrough.

Zero liquid discharge

Degrémont Technologies is the water treatment specialist within Suez Environment. The company's Zero Liquid Discharge system completely removes dissolved solids from wastewater and returns clean water to the process. Reverse osmosis may be used to concentrate the waste stream and return the permeate to the process. In this case, a much smaller volume (the reject) will require evaporation. In many cases, falling film evaporation is used to further concentrate the brine prior to crystallization.
