This report reviews the pressure drop (AP) and filtration performance of GE Energys QG061 filtration media. Environmental Technology Verification (ETV) testing of this technology/product was conducted during a series of tests in September 2008 by ETS Incorporated (ETS), under contract with the Air Pollution Control Technology Center (APCT Center). The objective of the APCT Center and the ETV Program is to verify, with high data quality, the performance of air pollution control technologies. Control of fine-particle emissions from various industrial and electric utility sources employing baghouse control technology is within the scope of the APCT Center. An APCT Center program area was designed by RTI International (RTI) and a technical panel of experts to evaluate the performance of particulate filters for fine-particle (i.e., PM2.5) emission control. Based on the activities of this technical panel, the Generic Verification Protocol for Baghouse Filtration Products was developed. This protocol was chosen as the best guide to verify the filtration performance of baghouse filtration products (BFPs). The specific test/quality assurance (QA) plan for the ETV test of the technology was developed and approved in May 2000, followed by an approved update in February 2006. The goal of the test was to measure filtration performance of both PM(sub 2.5) and total particulate matter (PM) as well as the AP characteristics of the GE Energy technology identified above.
