operating data. This should be used to track the performance of the system and help
identify any problems as early as possible.
The following parameters should be recorded at least once a day:
• Dilute Feed Pressure (psi, bar)
• Concentrate Inlet Pressure (psi, bar)
• Dilute Outlet Pressure (psi, bar)
• Concentrate Outlet Pressure (psi, bar)
• Pump Discharge Pressure (psi, bar)
• Concentrate Bleed Flow (gpm, m
• Concentrate Flow (gpm, m
• Electrode Flow (gpm, m
• Dilute Flow (gpm, m
The following parameters should be recorded on a weekly basis:
• Feed Hardness (ppm)
• Feed CO
(ppm)
2
• Feed Silica (ppm)
Sample Operating data log forms are located at http://www.ecell.com/.
The GEWPT E-Cell group developed the Field Monitoring Spreadsheet that automatically
normalizes data and produces graphs similarly to RO operating data normalization programs.
The spreadsheet helps to determine cleaning needs and gives early warning of potential
problems and is available at http://www.ecell.com/.
