Reverse Osmosis Membrane TDS Performance Calculator

       Simply enter your Feed Water TDS and RO Water TDS into the boxes below and click "Submit". The percentage of TDS (total dissolved solids) rejection will be displayed. We normally recommend RO membrane replacement once your rejection rate drops below 75%. This may vary to allow a lower percentage in areas with high TDS in the feed water.   Let the tap water and reverse osmosis water run for a few seconds before drawing your sample.  We have a large selection of both handheld and inline TDS meters in our Water Testing department.  Knowing the rejection rate is the only way to know if it is time to replace your reverse osmosis membrane.   We recommend testing often to ensure quality.
