Hydrologic Stealth-RO150/300 RO Membrane

#ad
Hydro-Logic Purification Systems #ad - If the rejection % falls under an acceptable level typically 90% it's time to change the membrane. Test the ro and source/inlet water to see what percentage of the inlet water’s ppm the 150 is filtering out rejection %.

If you change your pre-filters and the product water still flows slowly then it’s an indication you need a new membrane. Stealth-ro150/300 ro membrane reduces 89%+ of ppm of total dissolved solids. There are two indications as to when to change your membranes. This can also happen if your pre-filters are clogged. 2. When the flow rate of the product water slows down significantly. You should see approximately 98% of the inlet ppm’s being removed when the membrane is New. 1.
