William (Bill) A. Shaw, P.E. Senior Process Engineer at HPD, a Veolia Water Solutions Company, explained the CoLD™ Process which was developed to achieve zero liquid discharge for wastewater from wet FGD and IGCC 'grey water'. The salt separation energy requirement has been reduced by lowering the slurry temperature.

Modular ABMet* Introduction presented by James (Jay) Harwood - GE - Hot Topic Hour June 16, 2011.
Jay Harwood, Commercial Leader for ABMet at the GE Power and Water office in Oakville, Ontario, presented GE's new modular Advanced Biological Metals removal system (ABMet). This is a proven, reliable process to remove elevated levels of selenium and nitrate found in wastewater streams. The new modular design has made it less costly and more compact.

Michelle L. Briscoe, VP of Analytical Services at Brooks Rand Labs, observed that evaluating the effectiveness of specific FGD wastewater heavy metal removal methods requires the collection and analysis of samples for metals concentrations at each stage in the treatment process. Because of interferences, testing is showing metal concentrations which are much higher than actual. Brooks Rand Labs has developed methods to eliminate the interferences and provide accurate measurement.

Naomi Levy of Infilco Degremont discussed the many wastewater treatment systems which the company has supplied to treat power plant wastewater. A large system for Conemaugh is now under construction. Biological treatment can be added to the physical/chemical equipment when it is necessary to remove large quantities of selenium.

Ruediger Peldszus, Senior Manager for Applied Technology Advanced Intermediates at Evonik Degussa GmbH, backed up his claim that TMT 15® is a good choice for separating heavy metals from flue gas scrubber water by citing a large number of installations in coal-fired power plants and also waste incineration plants. When asked how the chemical impacted the gypsum quality, Ruediger explained that the resultant compound is very small and exits the top of the hydroclone and not with the gypsum through the bottom. TMT 15 can also prevent mercury re-emission from the scrubber but for this to be successful, the parameters must be carefully evaluated. One of the participants has a client who has been challenged to successfully use the TMT 15 to prevent re-emission
