Description
This slide presentation outlines factors effecting direct and indirect membrane integrity testing and pilot and full scale results from three different membrane manufacturers. Topics covered include: definition of Log Removal Value (LRV) and Pressure DecayTest;regulations on Membrane IntegrityTesting;Piloting Results;Full Scale Performance;How to Scale UpPilot Results to Full Scale; and, Design Criteria that Effect LRV. Conclusions indicated that: log credit awarded only as good as what canbe tested and measured;pilot scale results can be used to verifyeffectiveness of integrity test;ability to detect a single fiber breach duringpiloting is useful information but cannot bescaled up just linearly for full scale; the Engineer/Owner should considerLRVwhen defining design criteria andthroughout the design process to ensureoptimized design; feed concentration, start pressure andtest duration effect LRV<sub>DIT</sub>; specify direct integrity test method type; specify the required removal credit asLRV<sub>DIT</sub> at a given test pressure; and, with differences between membranemanufacturers, all the more reason tohave a competitive bid. Includes tables, figures.
