GrowMax Water 17” RO Membrane - Compatible with HydroLogic Evolution-RO

This RO Membrane (stored and ships dry) is compatible with the HydroLogic Evolution Reverse Osmosis System.

Removes up to 95%+ of total dissolved solids (TDS)

PERMEATE FLOW RATE VARIATIONS: Permeate flow rate will vary depending on the temperature of your feed water and the net driving pressure on the membrane element. If your system is running at baseline operating conditions, permeate rate should be at 100% (matching the manufacturer’s listed performance specs). Deviations from these baseline conditions will affect permeate flow rate. As feed water temperature and/or net driving pressure increases or decreases, permeate flow rate will proportionally increase or decrease.

You will need to calculate the adjusted permeate rate to compare or evaluate the performance of your membrane(s) and RO system. This involves calculating Corrected Temperature Permeate Rate and Corrected Net Pressure. Click here for instructions on how to calculate Corrected Temperature Permeate Rate and Corrected Net Pressure. Or just use our RO Flow Rate Calculator to see what your adjusted flow rate should be based on your filter and water supply.

INSTALLATION INSTRUCTIONS: Apply a thin layer of silicone lubricant to the 2 small o-rings on the membrane stem. Making sure to keep the membrane straight, carefully push the stem into the manifold until both o-rings are fully seated in the hole. Do not rock the membrane back and forth during installation. If you are replacing the carbon filter and membranes at the same time, be sure to flush your system for a minimum of 10 minutes with the new carbon filter installed BEFORE installing the membranes. This should be done any time you are replacing the carbon filter.

REPLACEMENT SCHEDULE: To keep your membrane in optimum working condition, we recommend replacing every 6 months – 2 years, or upon observing a decrease in flow rate and/or an increase of PPM. The life of your RO membrane(s) is dependent on proper pre-filtration maintenance, feed water quality, and clean water output.
