DEFINITION

Our water treatment calculator helps users with determining the membrane rejection rate of your reverse osmosis system in order to ascertain the degree of total dissolved solids found in the water, which includes metals, minerals, and salts that can be removed. So for instance, if your RO system has a 99% rejection rate, then that means the RO product water that has gone through the water treatment process has 99% less TDS solids than it did before it entered the system.

It should be noted that most RO membrane rejection rates lies between 80-100%, which is within the specifications of water treatment facilities. If the TDS rejection rate is below 80% then it is recommended to replace the RO membranes and other pre or post filtration technologies used with this system.
