‘Supply water at 55 psi and 77“F with 750 parts per million sodium chloride. Quality water production, amount
of waste water and percent rejection all vary with changes in pressure, temperature and total dissolved
solids. See the charts below for additional production and rejection rates.
t Up to 2.0 ppm removed by the RO prefilter cartridge.
NOTE; This product is tested and complies with Water Quality Association Standards.
You can use the following charts to determine RO performance for your specific water pressure and total dissolved
solids content. The results are from tests conducted on the RO membrane using a 9” long flow control at a 25% product
water recovery rate.
