Northeast coal fired power plant uses Evoqua ion exchange resins to remove vanadium from wastewater
When a coal-fired power plant in the Northeast discovered that the runoff from its ash pile contained vanadium levels exceeding discharge limits, it contacted Evoqua Water Technologies, for assistance. Test results showed ion exchange (IX) resin would remove roughly two pounds of metal for every cubic foot of resin. Calculations indicated the entire pond could be treated with less than 60 cubic feet of ion exchange media. The Evoqua’s solution featured two (2) 36” x 72” steel vessels, each containing roughly 30 cubic feet of resin. The tanks were installed in series with sampling ports after each vessel. The final effluent is sent to a holding tank for testing by a statecertified laboratory prior to discharge, to confirm that the vanadium level is within limits. When the resin in the vessels reaches capacity, the local Evoqua service branch is notified and delivers fresh tanks containing new resin to the site. Exhausted tanks are shipped to Evoqua’s RCRA-permitted treatment facility where the contaminants are removed from the resin and recycled into a raw material.

Audit by Evoqua results in power plant savings for power, chemicals and labor costs
An uninterrupted supply of high-quality water is vital to power plant operations. When making outage plans that include preventative maintenance on key plant systems, plant personnel should address the plant’s water treatment equipment, ensuring it receives the same high level of attention as its boiler, condensers, turbines and process equipment. So, how does a maintenance planner know whether the water treatment system is operating at its best and that it can meet the power plant’s current and future demands? One way is to plan an audit of the water treatment equipment before a planned outage. The audit should start with a system check-up to assess system conditions, performance and efficiencies and to pinpoint areas that need improvement. The check-up also can determine if a full system audit is required to provide a more in-depth investigation of a single or multiple water unit operation. The system audit should address the individual challenges of specific situations and include an in-plant survey and a summary of findings and recommendations for improvement.

Case History of a Water Treatment System in Puerto Rico
This paper reviews the lessons learned in designing, commissioning and operating a water treatment system consisting of depth filters, antiscalant feed, and cartridge filters as pretreatment, followed by a single pass reverse osmosis system and polished with a single pass electrodeionization system for a 300 MW, combined cycle co-generation power plant in Puerto Rico. This paper provides background on equipment selection, unit operation, water quality issues, system rework, operational problems, system profiling and validation protocol.

Electric Utility Chemistry Workshop, June 7-9, 2011, Champaign, IL, Exhibitors
Now in its 31st year, this comprehensive program features state-of-the-art information on controlling corrosion, improving operation efficiency, and meeting environmental challenges in fossil- and nuclear-fueled power plants. This year’s program is geared toward improved training and continuing education of personnel responsible for electric utility cycle and environmental chemistry. More than 3,000 chemists, consultants, and power plant administrators have attended the workshop since its inception in 1981. The 2011 program has been developed by a committee of representatives from midwestern electric utilities, the Illinois State Water Survey, the University of Illinois at Urbana-Champaign, and consultants serving the power industry. Some of the most popular features of the workshop are the Utility Experience presentations. Seasoned professionals from utility companies discuss their experiences on a range of topics. The entire workshop has been structured to encourage participation from attendees.
