| - | 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. | ||
