The Power of Ultrafiltration Membranes Market Trends

WebFor ultrafiltration, there are special considerations on flow rate. Flow Rate and Ultrafiltration During ultrafiltration, it is important to balance flow rate with retention to obtain optimal performance. With ultrafiltration membranes the term more commonly used is flux. A membrane’s flux is defined as flow divided by the membrane area. 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.
