1.1.8 Concentration
Concentration equals the Total Dissolved Solids (TDS) concentration of a solution expressed
as parts per million (ppm) or conductivity (microSiemens/cm).
C
f
= Feed Concentration
C
p
= Permeate Concentration
C
c
= Concentrate Concentration
C
avg
= Average Concentration in Machine
1.1.9 Salt (Ionic) Passage
The percent of dissolved salts passed through the membrane or 100% minus rejection.
1.1.10 Recovery
Permeate rate divided by feed rate, expressed as a percentage. For example, 33% recovery
means that for a given feed rate, 33% is produced as purified water (permeate).
1.1.11 Salt (Ionic) Rejection
The percent of dissolved salt rejected by the membrane, calculated from an average
concentration over the membrane.
