Luis Carvalho

Luis Carvalho (P.Eng.) is Founder & Owner of Industrial Water Treatment Academy (iwtA). He is also Principal Instructor and Consultant in industrial water technologies to a wide array of industries (power, chemical processing, hydrocarbon processing, pulp & paper, commercial & institutional, etc.).

Luis has since 1997 developed and presented many technical courses and workshops for engineers and other technical and operations staff in many areas of industrial water treatment, industrial water chemistry and heat-transfer. Many of these courses were delivered onsite to companies such as Shell Canada, Sunoco, Suncor, Syncrude, Nexen Energy, Excel Energy, and many others.

Luis is a licensed professional engineer (Professional Engineers Ontario, Canada); he is also a member of ASME (American Society of Mechanical Engineers) and NACE (National Association of Corrosion Engineers); he is actively involved with the International Association of the Properties of Water & Steam (IAPWS), and is the recent past Chairman of the Technical Sub-committee on Air In-leakage at IAWPS. He was also a member of both the Technical sub-Committee on Film Forming Substances and Technical sub-Committee on Demineralized Water Standards at IAPWS.

Luis’ professional career of 36 years in industrial water treatment includes experience in production, process development, and various technical and management positions. He held the position of Principal Engineer for over 7 years at ChemTreat, a Richmond, VA (USA) based multinational. Previously, he held the position of Senior Technical Consultant at GE Water & Process Technologies where he worked for 18 years, and Senior Process Engineer with a large multinational petrochemical group for many years. He has worked extensively in the United States and Canada, as well as more than a dozen other countries, including extensive involvement with commissioning and start-up activities. Luis is widely regarded as an expert in the power industry as well as in membrane separation technologies. He played a significant role in defining new criteria for steam purity for use in turbines and introducing changes to decades-long steam purity guidelines.

He is the author and co-author of many technical papers in the field of industrial water treatment ranging from Boiler/HRSG topics to Reverse Osmosis and water treatment plant design; he has been a speaker at numerous international conferences. He was the winner of the Paul Cohen Award in 2007 at the International Water Conference (IWC) in Pittsburg, USA. He has also been an instructor of Water Treatment Technology courses at various continuing technical education organizations.
