View Full Version : Concentrate/Product Ratio For Spectra Select Membranes???

Hi there,

I just replaced my membranes with two of the spectra select, 99% rejection membranes.

I seem to recall, but am not sure, seeing somewhere that the concentrate/product ratio can be as low as 2 for these membranes. Is that correct? I canít seem to find that anywhere now and would like to know before I cut the new flow restrictor. (System is a 180 gpd system with 2 90-gpd membranes.)
