Max-9TM ESFF

Max-9TM Electrostatic Fabric Filter

The Max-9 Electrostatic Fabric Filter is a dust collection 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 is fundamentally an

electrostatic precipitator/pulse-jet baghouse hybrid, 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 order of magnitude higher

than those achieved by either the best fabric filters or precipitators

currently on the market, with demonstrated efficiency of 99.999%.

GE is the exclusive licensee of this EPA-patented technology,

providing improvements over the original test design and

commercialized for full-scale applications. The extremely high

operating air-to-cloth ratio allows a small footprint, making them

easier to fit in the limited space of plant environments.

Additionally, the low pressure drop attribute is allowing many

sites to replace less efficient particulate control devices with

the MAX 9 ESFF without replacing expensive ID fans. Systems

can be configured to help provide compliance with Industrial

Boiler MACT, fine particulate reduction, and with PM1.0 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 collector

Polishing units behind an existing precipitator, baghouse, or

scrubber

Stand-alone as a high efficiency replacement for an

inefficient precipitator or multiclone

Benefits

60-80% reduction in static pressure across fabric filters

compared to conventional baghouses

Combines established, proven technologies to achieve

unprecedented efficiency

Designed to be used alone or in conjunction with SOx 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 technology

Allows operation at high air-to-cloth ratios

The Max-9 Electrostatic Fabric Filter is designed to help if

you:

Want to switch to low-cost fuels, but can't due to emissions

problems

Are planning for particulate matter or mercury regulation

requirements

Are running a borderline precipitator or baghouse that

needs more efficiency
