At permeate flow rates lower than shown in the column for Filtered Tertiary ffluent, maximum element recovery is 20%
for surface water and 15% for seawater.
Note: The limiting values listed above have been incorportated into the ROSA (Reverse Osmosis System Analysis)
software.
Design of systems in excess of the guidelines results in a warning message on the ROSA printout.

We recommend that minimum concentrate flow rates be increased at the discretionof the designer by 20% for feed
waters known to be high in fouling tendency (SDI>3).
