* Conductivity in the above procedure could be replaced by hardness, alkalinity, 
nitrate, phosphate, silica etc. (measured in ppm or mg/l).

Rejection of the RO Membrane Calculation Example

 

1.  Tap water hardness = 150 ppm (X)

 

2.  RO water hardness = 7 ppm (Y)

 

3.  X - Y = 143 ppm

 

4.  (X - Y) ÷ X = 143 ÷ 150 = 0.953

 

5.  Rejection = [ ( X - Y)  ÷ X ] ×100 = 0.953 ×100 = 95.3

 

Membrane Hardness Rejection = 95.3 % :  Membrane OK
