SpectraPure® Standard 40GPD RO Membrane -MEM-0040

Minimum Rejection = 96%

Stabilized Salt Rejection: 98%

The membranes produce the rated GPD ± 20% at 60 psi. (Permeate flow and salt rejection based on the following test conditions: 250 ppm softened water source, 77°F (25°C), 15% recovery and the specified applied pressure).

Membranes must be matched with flow restrictors. Always change the flow restrictor when changing membrane size on your system.

RO Membranes should only be replaced when the rejection rate has reached less than 96% or when production slows NOT due to cold water temperature.

RO Membranes life is all determined on prefilter maintenance, tap water chemistry, and many other factors. The best way to determine when to change an RO membrane is by using a TDS meter and System Performance Chart and logging parameters which will indicate a drop in rejection.
