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 conditions of alkali.
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.
It is suitable for stable operation in the pH range of 2-14.
Suitable for applications requiring severe chemical cleaning (CIP).
It is suitable for recovering high-temperature alkali cleaning liquid. The recovered cleaning liquid can be reused directly, which solves the problem of waste liquid discharge and reduces the production cost.
