Concentration

Concentration equals the Total Dissolved Solids (TDS) concentration of a solution
expressed as parts per million (ppm) or conductivity (microSiemens/cm).
C = Feed Concentration

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 out of 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.
