Note: EDI Systems must have a reverse osmosis permeate feed at 30 -40 psi and a flow rate that is 10% greater than the rated product flow of the EDI.
A. FCE = Conductivity + 2.79 (CO2
) + 1.94 (SiO2). Example: Conductivity = 5.0µS / cm, CO2 = 3.5 mg / l, SiO2
= 0.5 mg / l, FCE = 5.0+2.79 (3.5)+1.94 (0.5) = 15.71µS / cm
Note: Conductivity (µS / cm) ~ 2.22 TDS (mg / l)
B. Does not include operating space requirements.
