Meets dioxin emission requirements without the burden of costly new equipment. GORE® REMEDIA® Catalytic Filter Bags remove dioxins and furans (< 0.1ng/m3), provide dust control and work with existing baghouses in a variety of applications.
The threat of dioxins is drawing increasing attention around the world. Governments are phasing in tougher dioxin restrictions, and reports about dioxin levels in food products have generated widespread concern. Issues related to dioxin emissions and disposal are moving up the environmental agenda. With heightened public awareness, stricter regulations and potential penalties for non-compliance, it's more important than ever to avoid the risks associated with inadequate dioxin control.
"I am very pleased that we are eliminating almost all of our dioxin/furan emissions using the REMEDIA D/F catalytic filter system, rather than simply transferring the material from the flue gas to the solid residue stream, such as with activated carbon."
GORE REMEDIA Filter Bags help you efficiently meet dioxin emission requirements without the burden of costly new equipment. You can remove dioxins and furans simply by installing new filters in your baghouse. This innovative system is effective and cost-efficient. Safer for the environment, safer for employees, simpler to use.
GORE REMEDIA Catalytic Filter Bags offer substantial benefits over sorbent injection systems and other dioxin control technologies.
- Destroy gaseous dioxins.
Unlike sorbent based systems such as powdered activated carbon (PAC), GORE REMEDIA Filter Bags do not merely remove dioxin and furan molecules from the gas stream to the solid residue stream, they destroy them. They use a high-performing, state-of-the-art catalysts to assure long life and levels of destruction that in many cases exceed 99 percent. - Lowest Total Cost of Ownership.
By combining dioxin destruction and particulate control into one passive filter, GORE REMEDIA Filter Bags provide low total cost of ownership. Made of catalyst/PTFE fibers, they have high mechanical strength and durability coupled with a proven long life catalyst, effectively assuring savings well into the future. Because it doesn't add to your operating costs, there are no hidden costs after the system is purchased. - Lower disposal costs.
With no dioxin contaminated sorbents to dispose of, GORE REMEDIA Filter Bags minimize the cost of hazardous waste disposal. They address concerns about existing or future landfill restrictions on the amount and toxicity of sorbent levels in fly ash. Reducing hazardous waste disposal also demonstrates your company's commitment to environmental protection. - No Need to Purchase New Equipment.
No new capital equipment is required. GORE REMEDIA Catalytic Filter Bags simply replace your current filters in your current baghouse so you can optimize your existing assets. In addition, no new equipment means there is no need to change your current process or add new maintenance requirements. - Passive System - No Maintenance.
Gore's catalytic filter system is completely passive in operation, continuously destroying gaseous dioxins and furans while in operation. With no additional equipment to operate, ongoing maintenance demands are kept to a minimum. - Provide Dust Control.
The microporous structure of the GORE Membrane filters dust, even submicron particles. By capturing fine particles it reduces total emissions of toxins, such as trace heavy metals to the atmosphere. - Uses Existing Facility Footprint.
With no new equipment to buy, there are also no new demands on your existing facility footprint. Injection equipment, storage silos, catalytic towers, heat exchangers, etc., all require additional space and related construction. By utilizing your existing baghouse, GORE REMEDIA Filter Bags make compliance easy and affordable. - Reduce Corrosion.
The lower operating temperatures required with other dioxin control systems can cause corrosion in your baghouse. Since GORE REMEDIA Catalytic Filter Bags work at higher temperatures, there is less chance of corrosion. - Safer for Employees.
Carbon-based systems create a risk of baghouse fires. Hazardous carbon dust also puts operators at risk, especially when it is contaminated with dioxin. With GORE REMEDIA Filter Bags, avoiding carbon eliminates the risk of fires and minimizes potential health risks
"The best thing about REMEDIA D/F catalytic filters is that the system destroys dioxin instead of simply capturing it. There were no changes to our process or equipment. In addition, no operator is needed after these filters are installed."
GORE REMEDIA Filter Bags consist of a GORE Membrane (made of expanded polytetrafluoroethylene - ePTFE), laminated to a catalytic felt substrate.
Here's how GORE REMEDIA Filter Bags work:
- The GORE Membrane captures fine particulate on the surface of the filter.
- As the filter is cleaned, solids are released from the surface and collected in the bottom of the baghouse hopper.
- The gaseous dioxins and furans pass through the Membrane into the catalytic felt. The catalyst instantly reacts with the dioxin and furan molecules to convert them into insignificant amounts of CO2, H2O and HCl.

GORE REMEDIA Catalytic Filter Bags - Combining the principles of surface filtration and catalysis.
Combining the principles of surface filtration and catalytic filtration, GORE REMEDIA Filter Bags are a unique dioxin control alternative that works in your existing baghouse to destroy gaseous dioxins and furans to levels far below regulatory limits — safely, economically, and with minimal maintenance.
The GORE REMEDIA Catalytic Filter Bags are installed in some of the world’s largest incinerators to simultaneously provide dust control and remove up to 99% of gaseous dioxins and furans.

GORE REMEDIA Filter Bags work in your existing baghouse, without process modifications or changes to your physical plant.
In a variety installations globally (municipal waste incinerators, hazardous, medical and industrial waste, crematoriums and pyrometallurgical plants) the GORE REMEDIA Catalytic Filter System yielded dioxin emissions at levels far below the standard guideline of 0.1 ng (TEQ)/Nm3. Furthermore, analysis revealed that the concentrations of dioxin in the fly ash using the GORE REMEDIA Catalytic Filter System were significantly lower than those achievable using a powder activated carbon (PAC) system.
Total dioxin and furan emissions to the environment - including release of both gas and solids from the baghouse - were reduced more than 90% compared to PAC systems.
At facilities operating under good combustion practices - a typical inlet dioxin concentration below 10 ng (TEQ)/Nm3 - the GORE REMEDIA Catalytic Filter System is designed to meet and exceed dioxin regulations.

The continuous operating temperature range is 180° to 260°C, allowing for temporary surges to 274°C. Operation below 180°C is possible for certain applications. Contact Gore for more information.
If your air-to-cloth ratio is below 1.2 m/min (4 ft/min), then no change is necessary. If it is above 1.2 m/min (4 ft/min), then a system evaluation will be necessary to ensure that excessive velocity abrasion or lift velocity will not damage the filters or cause high differential pressures.
Product life consists of both chemical and mechanical aspects. On the chemical side, our catalyst suppliers have provided data indicating that their catalysts have lasted up to ten years in the industrial processes where the REMEDIA Catalytic Filter System is being used. Moreover, based on our historical data, we are applying catalysts designed to meet the needs of specific industrial processes. This should optimize the chemical life of the catalyst in specific applications.
An expanded polytetrafluoroethylene (ePTFE) fiber is inherently very strong and chemically inert. With nearly 30 years of ePTFE filtration experience behind us, we feel confident that the REMEDIA Catalytic Filter System will not fail mechanically within five years.
In general, your plant's normal procedure for filter disposal should be followed. Since the catalyst is an integral part of the felt, the catalyst itself has no way of escaping from the filter. The characterization of the filter as nonhazardous versus hazardous waste is governed by the dust on the filter, not by the catalyst itself. This has been proven through rigorous EPA-mandated tests.
The REMEDIA Catalytic Filter System is not selective; it destroys all toxic PCDD/F isomers.
The ePTFE substrate is chemically inert so it has excellent resistance to both acidic and alkaline environments. The catalyst has been shown to resist poisoning in severe chemical environments. Please contact Gore for details as they apply to your application.
In terms of total cost of ownership, the REMEDIA Catalytic Filter System is less expensive than an activated carbon injection system. The cost is dependent on the application size, dioxin removal requirement, and operating conditions. To obtain cost information for your project, please contact us.
