Enter the RO Water (gallons) and the total water (gallons) into the calculator to determine the RO Efficiency. 

RO Efficiency Formula

The following formula is used to calculate the RO Efficiency. 

Ero = RW / TW *100
  • Where Ero is the RO Efficiency (%)
  • RW is the RO Water (gallons) 
  • TW is the total water (gallons) 

To calculate the RO efficiency, divide the RO water by the total water, then multiply by 100 to express the result as a percentage.

How to Calculate RO Efficiency?

The following two example problems outline how to calculate the RO Efficiency.

Example Problem #1:

  1. First, determine the RO Water (gallons). In this example, the RO Water (gallons) is given as 300.
  2. Next, determine the total water (gallons). For this problem, the total water (gallons) is given as 600.
  3. Finally, calculate the RO Efficiency using the equation above: 

Ero = RW / TW *100

Inserting the values from above and solving the equation: 

Ero = 300 /600 *100 = 50 (%)


FAQ

What is RO Water?

RO Water refers to water that has been purified through Reverse Osmosis, a process that removes contaminants from water by using pressure to force water molecules through a semipermeable membrane.

Why is RO Efficiency important?

RO Efficiency is important because it measures how effectively the reverse osmosis system is working. A higher efficiency means more contaminants are being removed, resulting in purer water. It also indicates the system’s cost-effectiveness and environmental impact.

Can RO Efficiency be improved?

Yes, RO Efficiency can be improved by regular maintenance of the RO system, including cleaning and replacing filters and membranes as needed. Ensuring the system operates under optimal conditions and pressure can also enhance efficiency.
