Summary of Expertise: Listed with other top experts in: 
Expert is an international expert in odor and corrosion control in waste handling facilities, and has extensive experience in the measurement and assessment of odor/corrosion problems, the evaluation of control technology, and the implementation of odor and corrosion control strategies. He has collected hundreds of air samples from odorous processes and has overseen the analysis of these samples for odor concentration (dilutions to threshold), reduced sulfur compounds via GC-FPD, and volatile organic compounds via GC-MS. He was one of the first practitioners to use the EPA-developed flux chamber to estimate emission rates of odor and odorous chemicals from various waste treatment process. Through his 25+ years' experience in the odor control field, he is knowledgeable regarding the sources and causes of odor generation in municipal and industrial waste treatment processes. He has conducted air dispersion modeling to estimate the downwind impact of odorous emissions. Expert utilizes sound, scientific methodologies to assess and rank the sources of odor at facilities with multiple odor sources.

As a professional engineer, Expert has state-of-the-art knowledge regarding the technologies utilized to minimize and control odors. He has designed innovative enclosures around waste processing equipment to minimize the volume of air to be treated and to improve conditions for workers. He has evaluated and designed the full range of odor treatment technologies including activated carbon adsorbers, packed-tower scrubbers, in-ground and in-vessel biofilters, bioscrubbers, and others. Expert also designed innovative systems to economically treat odorous air in the aeration tanks of wastewater treatment plants. He contributed a chapter on odorous air treatment for the Water Environment Federation's 2004 Control of Odors and Emissions from Wastewater Treatment Plants.

Expert is an expert in the detection, monitoring, and control of hydrogen sulfide corrosion in sewers and waste handling systems. He has performed numerous assessments of sewer corrosion that has included continuous hydrogen sulfide monitoring, concrete pH testing, estimates of concrete loss, etc. He has conducted modeling to predict sulfide build-up in wastewater and the corrosion rates of concrete pipe affected by hydrogen sulfide.

Expert has evaluated and field-tested numerous chemicals designed to control hydrogen sulfide in sewers. These have included iron salts such as ferrous chloride and ferrous sulfate; oxidants including hydrogen peroxide, sodium hypochlorite, potassium permanganate, and sodium chlorite; pH adjusters such as magnesium hydroxide and sodium hydroxide; and nitrate-containing solutions designed to prevent hydrogen sulfide generation. Expert has had extensive experience with injection of pure oxygen for sulfide control, having designed the first U.S. “multiple U-tube oxygen dissolver” for controlling sulfide generation in a force main.

Expert has been an active member of the Water Environment Association's Odor and Air Quality Committee for over 10 years, and previously served on the WEF Corrosion Control Task Force. He has made numerous technical presentation on odor and corrosion control for the Water Environment Federation, International Water Association, Air and Waste Management Association, New England Water Environment Association, Virginia Water Environment Association, Florida Water Environment Association, and other organizations. He has conducted training sessions for pollution control agencies in Massachusetts, New Hampshire, and Maine.

International Experience:
Years   Country / Region   Summary
2006 to 2010   Canada/Toronto, Ontario   Expert participated in the Value Engineering Program for the proposed Humber WWTP odor control improvements in Toronto. New recommendations developed by the VE Team resulted in significant projected savings in both capital and O&M costs. Expert was subsequently part of the design team for the improvements, which consisted largely of containment of the odors followed by treatment in organic media biofilters.
1992 to 2010   Canada/Edmonton, Alberta   Expert has worked with a large Canadian engineering firm on multiple projects involving odors and corrosion in the sewer system, treatment plant, and off-site sludge treatment/storage facility serving the City of Edmonton, Alberta.
1992 to 1993   Republic of Singapore   A comprehensive study was undertaken to assess odor emissions from the 75 mgd Ulu Pandan Sewage Treatment Works in Singapore, and to make recommendations for their control. A seven-day intensive sampling and analytical program was implemented, including on-site odor panels to determine odor detectability and intensity, and characterization of various liquid streams. Ambient odor surveys were conducted to document downwind odor levels.

The project involved major technical challenges in developing recommendations to control odors from the facility. The goal was to reduce buffer area around the facility to a minimum, and to design covering and control facilities which were aesthetically pleasing. Considerations of operator access and safety were critical due to the high H2S levels. Multi-stage odor control systems were required to meet the stringent requirements associated with reduced buffer distances.

2003 to 2003   Australia - Gold Coast   Expert assisted a large Australian engineering firm in a Gold Coast (Queensland) project, where high levels of hydrogen sulfide were causing odor and corrosion problems in the sewer system of a resort community.

Expert also provided technical assistance on a related project involving a major expansion of a sewer system that required provisions for both odor and corrosion control.

1995 to 1997   Canada/Edmonton, Alberta   The Capital Regions Sewerage Commission near Edmonton, Alberta had experienced corrosion in a large gravity interceptor sewer which receives the discharge of four long force mains. Expert was retained by the Commission's engineer to assist in evaluating the extent of the problem and to develop alternatives to control the corrosion.

Expert developed a sampling program to measure sulfide levels in the discharge of the tributary force mains and in the wastewater along the gravity interceptor sewer. These data were then input into the Pomeroy-Parkhurst corrosion model to identify locations with the highest potential for corrosion problems. Subsequent core borings confirmed the predicted extent of corrosion damage in the concrete interceptor sewer. Laboratory and pilot studies were then conducted to evaluate alternatives to control sulfide levels and corrosion rates. Recommendations included caustic slugging in the force mains and regular monitoring of dissolved sulfide and atmospheric H2S levels.
