WebUse the minimal amount of chemical contact time to prolong membrane life. • A ‘gentle’ pH range is 4–10, while the harshest is 1–12. Extremes of pH have an adverse effect on the life of RO and NF membranes. During recirculation, the temperature, must be less than 50°C at pH 2–10; <35°C at pH 1–11, and 30°C at pH 1–2 for PA membranes. Ultrafiltration Rate Calculator Are you in the green? Pulling water out of your blood at dialysis is “ultrafiltration" (UF). A safe UF rate (UFR) for HD is gentle—and you may feel well after a treatment.
