The SPI management team contributes several years of membrane separation processes and water treatment experience. Their knowledge of microfiltration membrane, ultrafiltration, nanofiltration and reverse osmosis treatment processes has supported the successful outcome of many water treatment and membrane engineering projects.

Gerry Filteau - President

Mr. Filteau has over thirty-five years experience in the application of membrane separation processes to water and wastewater treatment. Based on his extensive experience in process engineering of membrane systems, feasibility studies, pilot studies, and full-scale operations support, he manages a variety of major projects including SPI's seawater desalination activities. Having joined SPI in 1998, he previously held the position of Director of Applications Engineering at Fluid Systems Corporation (Now Koch Membrane Systems), a manufacturer of reverse osmosis, nanofiltration and ultrafiltration membranes. During his seventeen years with that firm, he was active in a wide range of engineering activities, including process design, membrane selection, pilot study management, system startup and membrane system troubleshooting. Mr. Filteau holds a Bachelor of Science Degree in Civil Engineering from the University of Massachusetts (Lowell).


Alex Wesner, P.E. - Vice President

Mr. Wesner has over twenty-five years of experience in the planning, design, construction, startup and operations of membrane treatment facilities. He has successfully managed the membrane process design of some of the most advanced water reclamation projects for supply of low and high pressure boiler feeds in refinery applications. He has managed six (6) integrated membrane projects for the West Basin Municipal Water District in El Segundo, California as well as the East Bay Municipal Utilities District. He has managed drinking water projects for Irvine Ranch Water District, South Coast Water District and for the Chino Basin Desalting Agency (CDA). He has extensive experience in pilot testing and procurement of membrane equipment having assisted with the procurement of over 15 membrane treatment systems. He has experience in a wide range of technologies and applications including membrane filtration, nanofiltration and reverse osmosis. Mr. Wesner holds a Bachelor of Science in Chemical Engineering from the University of California at San Diego and is a Registered Chemical Engineer in California .


James Vickers, P.E. - Vice President

Mr. Vickers has over thirty years of experience in the planning, design, construction and implementation of membrane treatment processes for water and wastewater. His main area of emphasis has been membrane filtration. From 1988 to 1993, Mr. Vickers was Applications Engineering Manager for the Memcor product line and assisted in the development of microfiltration for municipal drinking water and wastewater treatment. Beginning in 1993, Mr. Vickers held project engineering positions with another consulting firm and was responsible for overseeing the implementation of membrane technologies nationwide. Mr. Vickers is a primary author of the AWWA MF and UF Manual of Practice (MOP) chapters on Design of MF/UF Systems and Costs of MF/UF Systems and was a primary contributor for the development of the USEPA Membrane Filtration Guidance Manual. He has been vice-chairman and chairman of the AWWA Membrane Process Committee and has successfully managed the process design for a number of membrane treatment facilities, including the San Patricio, Texas, 7.8 mgd Plant C WTP, City of Scottsdale, Arizona, 29 mgd Chaparral WTP and the Yucaipa Valley Water District 12 mgd Microfiltration/Nanofiltration Project. Mr. Vickers is a Registered Professional Engineer (Chemical) in California, Arizona, Oregon and Virginia and holds a Bachelor of Science Degree in Chemical Engineering from Youngstown State University and a Master’s Degree in Engineering Management from George Washington University.


Charles Cruz, P.E. - Vice President

Mr. Cruz has over 20 years of experience in the design of water, wastewater and water reclamation facilities. His assignments have included feasibility studies, managing pilot testing programs, preparation of procurement documents, equipment selection, life-cycle evaluations, and detailed design and construction administration services. Mr. Cruz is a Registered Civil Engineer in California and holds a Bachelor of Science Degree in Chemical Engineering and Master of Science Degree in Civil Engineering from Stanford University.


John Perlman - Manager Membrane Support Services

Mr. Perlman is a Project Manager and chemical engineer with extensive experience in membrane process design application and equipment design and construction of municipal and industrial membrane water treatment projects. Mr. Perlman has participated in the design and fabrication of numerous large membrane filtration and reverse osmosis systems. John manages the Membrane Support Services of SPI. These activities involve providing support services for numerous full-scale MF, UF, NF, RO, and integrated membrane systems treating potable and reclaimed water supplies for municipal clients. While managing a team of engineers, Mr. Perlman’s responsibilities have included continuous performance monitoring, periodic performance audits, process and equipment troubleshooting and optimization, and operator training for a variety of membrane facilities. He has served as RO process consultant to RO energy recovery equipment and RO membrane manufacturers bringing his extensive experience with seawater RO design and process control to the proper application of energy recovery and membrane technology. Mr. Perlman holds a Bachelor of Science Degree in Chemical Engineering from the Tufts University.
