February 2009Hydromantis Research Cited in Testimony before U.S. House of Representatives
The second report mentioned in Mr. Reinhardt’s testimony produced an estimating tool that municipalities can use to compare the life cycle costs of different technologies for recovering the energy in digester gas. Hugh Monteith and colleagues from the University of Toronto constructed the LCAMER (Life Cycle Assessment Manager for Energy Recovery) model incorporating factors such as site-specific wastewater plant characteristics, costs for energy recovery equipment and energy, and the cost of borrowing. With these factors entered in the model, cities can compare the relative costs of technologies such as engine-generators, turbines and fuel cells. An additional useful feature of the LCAMER (Life Cycle Assessment Manager for Energy Recovery) included the potential for including greenhouse gas reduction credits. For further information, please contact info@hydromantis.com. October 2008WEFTEC 2008In October, Hydromantis will attend the WEFTEC 2008 conference in Chicago, Illinois.

Hugh’s paper (title given below) described the development of the LCAMER (Life Cycle Assessment Manager for Energy Recovery) tool for determining the optimal use of anaerobic digester gas for on-site energy recovery. The LCAMER model was the end result of a four-year project led by Hydromantis Inc. and the University of Toronto for the Water Environment Research Foundation. Cost-effective energy recovery from anaerobically treated wastewater solids (LCAMER model). Hugh Monteith Hugh Monteith was invited by the Metropolitan Washington Council of Governments to present a paper at the workshop on Maximizing the Dual Benefits of Advanced Wastewater Treatment Plant Processes: Reducing Nutrients and Emerging Contaminants, held in Washington D.C. on May 12 and 13. Hugh’s paper (title given below) discussed the implications for energy consumption and greenhouse gas emissions by seeking to remove conventional and emerging wastewater contaminants to exceedingly low concentrations. Energy costs and greenhouse gas impacts associated with removing emerging contaminants. Hugh Monteith April 2008Paper by Hugh MonteithAt the Ontario Water Works Association Annual Conference and Trade Show, April 27-30, Hugh Monteith presented a paper on the successful integration of Hydromantis’ WatPro water disinfection simulator with the SCADA system of the city of Toronto’s FJ Horgan Water Treatment Plant.

Some background on Lübeck: Lübeck was founded in 1143 as the first German city on the Baltic Sea and is a UNESCO World Heritage Site. It prospered until the 16th century as the major trading centre for northern Europe. It is famous for its beautiful 15th- and 16th-century patrician residences, public monuments (e.g. the famous Holstentor brick gate), and gothic churches. Lübeck is also known for its legendary marzipan, a confection used in chocolates and cakes.

On February 4, 2009, Glenn Reinhardt, the Executive Director of the Water Environment Research Foundation (WERF) appeared before the U.S. House of Representatives Subcommittee on Water Resources and Environment, providing testimony on sustainable wastewater management. In his written remarks, Mr. Reinhart made reference to two WERF projects managed and delivered by Hydromantis Inc. One study, produced by Hugh Monteith and Youssouf Kalogo of Hydromantis Inc. for WERF and co-members of the Global Water Research Coalition, examined the current state-of-knowledge on opportunities for recovery of energy and other resources from wastewater residual solids. Besides use of energy-rich digester gas which can be used in on-site combined heat and power projects, the wastewater residuals can be “mined” for phosphorus, nitrogen, building material aggregates and other useful products.
