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.
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.
