E-MAIL: U.S. EPA Contracts Management Division -- Cincinnati, schellhas.hans@epamail.epa.gov. The U.S. EPA requires a drinking water treatment pilot plant PC-based data acquisition and analysis system. The pilot plant treatment train consists of coagulation, flocculation, sedimentation and filtration processes. Monitoring parameters include turbidity, temperature, pH and particle counts. Measurements of each parameter must be simultaneously made at as many as 9 sites. The pilot plant is unique in that the total system flow rate is only 100 ml/min through primarily 1/2" and 1/4" diameter teflon and stainless steel tubing. Data from monitoring devices and sensors must be collected by a central processor center (high speed personal computer) and data viewing and measurement options must be controlled by a computer and appropriate software. Data output must be in a form that is easily transferable to common spreadsheet and graphical packages including Microsoft Excel and Sigma Plot. The ability to manually discontinue/continue monitoring during sample events is a software requirement. A portable computer with the loaded pilot plant control software must be included to perform data analysis Aoff-site@ and remote monitoring of the pilot plant during hours when the system is not staffed. The appropriate connections from the monitoring probes to the control center must be a able to reach at least 100 feet in length. The package must include installation assistance, software training and basic hardware maintenance training to EPA staff.
