Acid-resisting NF-500

Device display
  • Equipment details
  • The vast majority of membrane components on the market are applicable to the pH range of feed solution 2-11. However, many pharmaceutical / biochemical / food industrial applications require production under harsh acid conditions.


    FFM Inc membrane has super stability and meets the application requirements of high and low pH value, high temperature (up to 158 ° f or 70 ° C) and organic media in the market.


    The acid resistant membrane element with rich membrane is suitable for stable operation in the pH range of 0-12.


    Suitable for applications requiring severe chemical cleaning (CIP). It is suitable for recovering high-temperature acid-base cleaning solution. The recovered cleaning solution can be reused directly, which solves the problem of waste liquid discharge and reduces the production cost
