Real-time Monitoring and Speciation of Selenium in Pulverized Coal Power Plant Wastewaters

Ohio Lumex Co- will develop a novel approach to real-time monitoring and speciation of selenium in coal-fired power plant wastewaters- The proposed technology will be developed in response to EPA’s recently issued Effluent Limitations Guidelines pertaining to selenium content in effluent streams from steam power generation plants- The proposed technology will be designed for real-time monitoring and speciation of selenium at concentrations, flow rates, pressures, and temperatures present in power plant wastewaters- The proposed approach will take advantage of the company’s resources and experience with real-time measurement of gas phase mercury using Zeeman Atomic Absorption Spectrometry, as well as thermal speciation, as demonstrated by prior research in thermal speciation of mercury in liquid samples-
