EE&T is a full service consulting firm that is known for its particular expertise in the area of conducting bench- and pilot-scale treatability studies. Our knowledge of scale down techniques comes from a strong background in process design by the firm’s managers. EE&T’s President, Dr. David Cornwell, P.E., was instrumental in the development of scale up/down to accurately define water plant conditions through simulation research. This work has been fundamental to much of the basic bench-scale work being undertaken today.

Since EE&T’s inception in 1985, it has designed and conducted numerous bench and pilot studies and this work has steadily increased to nearly 100 projects in all. EE&T recently completed the design and construction of a $1.2 million permanent pilot facility for ECWA in New York. EE&T’s treatability work over that time has been fairly evenly split between bench and pilot projects.

EE&T has extensive experience in designing and operating advanced treatment pilot plants. We were selected from a field of other nationally known firms to design and operate advanced pilot plants throughout the U.S. For example, we designed and operated ozone/BAC/GAC pilot plants for Tulsa, OK; Erie County Water Authority, NY; Appomattox River Water Authority, VA; Washington, NC; Marine Corps Air Station-Cherry Point, NC; and Durham, NC. All of these projects resulted in significant contributions to treatment, or resulted in design criteria for new processes.

EE&T has developed a specialist reputation over the years because of our experience in operating advanced pilot plants that include ozone, BAC, GAC, membranes, and high rate processes including DAF. Our firm has the equivalent of more than 100 months or 8 years of experience in running GAC and ozone pilot projects. We also have the equivalent of more than 2 years of operating experience in conducting membrane and dissolved air flotation pilot investigations. EE&T has vast experience in the operation of conventional pilot-scale projects.

That experience includes over 100 months of conventional pilot plant operation and over 90 months of filter media evaluations. Our firm has also conducted pilot plant evaluations of several high rate processes, including tube settlers, plate settlers, and upflow clarification processes. Our combined high rate pilot plant operating experience equals more than 35 months of operation. EE&T’s cumulative experience in running conventional pilot-scale projects of over 22 years.
