8. START UP
8.1 GENERAL OVERVIEW
The basic steps involved in the system start up are:
1. Fill the system with Reverse Osmosis quality water, or better
2. Set dilute flow
3. Start the concentrate pump and establish concentrate flow
4. Set concentrate bleed flow
5. Set the concentrate inlet pressure
6. Set the concentrate outlet pressure
7. Set the electrode flow
8. Start the rectifier
8.2 START UP
Once the E-Cell Stacks™ are ready for start up, the Concentrate Loop must be filled. The
initial filling is done with R.O. permeate (or other high quality water). The feed water must
always meet all the quality requirements, this will require the R.O. to be rinsed to quality
before being placed into Service and sending water to the E-Cell System™. The conductivity
of the Concentrate loop will initially be the same as the Feed water conductivity.
In order for the E-Cell Stacks™ to function effectively, the Concentrate Loop should have an
operating conductivity of 50-600 µS/cm. In some cases, it may be necessary to inject
concentrated brine into the Concentrate Loop in order to raise the conductivity once the
system is operating.
E-Calc spreadsheet indicates if brine injection is necessary and calculates expected
concentrate conductivity based on feed water analysis and recovery.
