MF/UF Direct Retrofit Solutions with High Performance TIPS Hollow-Fiber Membranes

The last twenty years of the UF industry has been dominated by system manufacturers who provided their own proprietary modules and unique system designs. While this has changed somewhat in the past few years with the advent of the universal UF rack, a need has emerged from the base of installed capacity. Customers are looking for choices when purchasing replacement modules particularly when performance of the original membranes was poor or the cost of the replacement has been too high. An overview of direct membrane retrofit solutions as well as a discussion of the differences in PVDF hollow-fiber manufacturing techniques (TIPS vs NIPS) and how the TIPS process results in a membrane with significant operational benefits in terms of mechanical strength, chemical tolerance, permeability and durability. Case studies for several retrofit projects will be discussed.
