Common Data Questions: 58 and 59
A reverse osmosis unit treats feed water (F) containing fluoride and its output consists of a permeate stream (P) and a reject stream (R). Let CF, CP, and CR denote the fluoride concentrations in the feed, permeate, and reject streams, respectively. Under steady state conditions, the volumetric flow rate of the reject is 60 % of the volumetric flow rate of the inlet stream, and CF = 2 mg/L and CP =0.1 mg/L.
Q.
The value of CR in mg/L, up to one digit after the decimal point, is
Important : you should answer only the numeric value

Given information:
- Feed water (F) contains fluoride with concentration CF = 2 mg/L.
- Permeate stream (P) has a fluoride concentration CP = 0.1 mg/L.
- Reject stream (R) has a volumetric flow rate of 60% of the inlet stream.
- The question asks for the concentration of fluoride in the reject stream, CR.
Approach:
To find the concentration of fluoride in the reject stream, we can use the mass balance principle. According to the principle, the mass of fluoride in the feed water should be equal to the sum of the mass of fluoride in the permeate stream and the reject stream.
Mass balance equation:
Mass of fluoride in feed water = Mass of fluoride in permeate stream + Mass of fluoride in reject stream
Calculating the masses of fluoride:
- Mass of fluoride in feed water = CF * Volumetric flow rate of feed water = 2 * F
- Mass of fluoride in permeate stream = CP * Volumetric flow rate of permeate stream = 0.1 * P
- Mass of fluoride in reject stream = CR * Volumetric flow rate of reject stream = CR * 0.6 * F
Applying the mass balance equation:
2 * F = 0.1 * P + CR * 0.6 * F
Simplifying the equation:
2 = 0.1 * (P/F) + 0.6 * CR
Substituting the given values:
2 = 0.1 * (0.1/2) + 0.6 * CR
2 = 0.005 + 0.6 * CR
1.995 = 0.6 * CR
Solving for CR:
CR = 1.995 / 0.6
CR ≈ 3.325
Rounding CR to one decimal place:
CR ≈ 3.3
Therefore, the value of CR in mg/L, up to one digit after the decimal point, is 3.3.
- Feed water (F) contains fluoride with concentration CF = 2 mg/L.
- Permeate stream (P) has a fluoride concentration CP = 0.1 mg/L.
- Reject stream (R) has a volumetric flow rate of 60% of the inlet stream.
