How many times should the TDS settings on the RO be set compared to the normal product TDS?

The TDS (Total Dissolved Solids) settings on the reverse osmosis (RO) system are crucial for ensuring optimal performance and water quality. Setting the TDS level too low can lead to unnecessary strain on the RO system, while setting it too high can compromise the quality of the water produced.

Setting the TDS levels at 2 times the normal product TDS ensures that the RO system operates within an effective range, allowing for adequate purification while not overworking the membranes. This balance helps maintain membrane longevity and effectiveness. It is a best practice in water treatment to adjust settings reflecting the product water's expected quality, and a multiplier of 2 is commonly regarded as appropriate for maintaining a manageable level of dissolved solids while ensuring that the system remains efficient.

In summary, setting the TDS level to twice the normal product TDS maximizes efficiency and water quality, making it the most effective choice for RO system operation.
