Abstract : An eductor developed under the Dredging Research Program (DRP) was field tested at the existing sand bypass plant at Indian River Inlet, Delaware. Field measurements of slurry velocity, percent solids, production rate, slurry specific gravity, supply pump pressure, booster pump suction, booster pump pressure, and supply pump suction were made for this eductor and compared to analogous measurements of the existing Indian River Inlet (IRI) eductor. Though the DRP eductor was specifically intended for a fixed bypass plant with significant debris problems, the mobile Indian River Inlet plant proved to be a useful field test location because of existing instrumentation and similar hydraulic requirements for both eductors. Results showed that the DRP eductor outperformed the IRI eductor with an increased 11-percent production rate. Operational and environmental influencing factors were taken into consideration for each set of test runs and were shown to be either equal for each eductor or insignificant. -BKA
