## Max-9TM ESFF

Max-9TM Electrostatic Fabric Filter The Max-9 Electrostatic Fabric Filter is a dust col lection technology that combines discharge electrodes and fabric filters in the same casing to provide the highest collection efficiency (99.999%) while operating at a 60 to 80% lower system pressure drop. The Max-9 ESFF i s fundamentally an electrostatic precipitator/pulse-jet baghouse hybri d, employing high voltage discharge electrodes to charge particulate, but with fabric filters instead of collecting plates in the casing. The technology was developed through a partnership of the Environmental Protection Agency (EPA) and Southern Research Institute (SRI) to address fine particulate and the need for a compact footprint. The Max-9 ESFF provides collection efficiencies an orde r of magnitude higher than those achieved by either the best fabric filte rs or precipitators currently on the market, with demonstrated efficien cy of 99.999%.

GE is the exclusive licensee of this EPA-patented t echnology, providing improvements over the original test desig n and commercialized for full-scale applications. The extremely high operating air-to-cloth ratio allows a small footpri nt, making them easier to fit in the limited space of plant environ ments. Additionally, the low pressure drop attribute is al lowing many sites to replace less efficient particulate controldevices with the MAX 9 ESFF without replacing expensive ID fans. Systems can be configured to help provide compliance with I ndustrial Boiler MACT, fine particulate reduction, and with P M1.0 and mercury abatement regulations as the Max-9 removes fine particulate precursors and sorbents such as carbon and lime. Potential configurations are: Slipstream units to augment an existing dust collec tor Polishing units behind an existing precipitator, ba ghouse, or scrubber Stand-alone as a high efficiency replacement for an inefficient precipitator or multiclone
Benefits 60-80% reduction in static pressure across fabric f ilters compared to conventional baghouses Combines established, proven technologies to achiev e unprecedented efficiency Designed to be used alone or in conjunction with SO x and mercury control systems Scalable design permits rapid installation and short outage duration Offers 80-90% reductions in sub-micron particulate matter emissions Smaller footprint than any other collector technolo gy Allows operation at high air-to-cloth ratios The Max-9 Electrostatic Fabric Filter is designed t o help if you: Want to switch to low-cost fuels, but can't due to emissions problems Are planning for particulate matter or mercury regu lation requirements Are running a borderline precipitator or baghouse t hat needs more efficiency Select Language
