This slide presentation begins by outlining and overview of Membrane Filtration under the LT2ESWTR that includes Potential Benefits of Challenge Testing, Membrane Filtration Processes, Applicable Membrane Media / Membrane Module Configurations, and Key Membrane Filtration Concepts. Topics outlined under the subject of Challenge Testing include: the purpose of challenge testing is to demonstrate the removal efficiency of a membrane filtration module; Test Organization Qualifications; Challenge Testing Protocol Design; Manufacturer Verification of Production Modules; Selecting Modules for Testing; Small-scale Module Testing; Test Equipment and Scale; example of a challenge test schematic; Selecting a Suitable Surrogate; potential surrogates; Maximum Challenge Level and Sampling; Analysis and Reporting of Challenge Test Data Calculation of the LRV; and, considerations in Grandfathering Challenge Test Data.
