5. For example:
If the Inlet TDS measurement is 600 ppm and the outlet TDS measurement is 48 ppm,
then
600 ppm – 48 ppm
600 ppm
x 100 = 92% TDS reduction
This means that the MRS-200 system has removed 92% of the dissolved solids from the
inlet water.
6.
The RO cartridge should be changed every 1 to 1-1/2 years or when the percent
reduction falls below 90%.
A form has been provided below to record these measurements and monitor system
performance.
