- | Do the following calculation to get a percentage: | + | * Measure the conductivity after the reverse osmosis membrane |
- | 100 * (TDS reverse osmosis) / (TDS raw water) = x% | + | * Measure the conductivity of the tap water |
+ | * Do the following calculation : 100 * (conductivity reverse osmosis) / (conductivity raw water) | ||
+ | * If the value is less **than 10%**, the membrane is still usable | ||
- | If the value is less **than 10%**, the membrane is still usable. | ||
In the other case, the reverse osmosis membrane begins to saturate. | In the other case, the reverse osmosis membrane begins to saturate. | ||
