Dioxin & Furan Control – GORE REMEDIA

Filter Bags that meet 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.

AST Canada provides GORE REMEDIA catalytic filter bags for your baghouse to remove & destroy up to 99% of the dioxins & furans without replacing your collector.

Meeting the Dioxin Challenge

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.

Eliminating Dioxins

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 and simpler to use.

A Cost-effective Solution for Dioxin & Furan Abatement

Dioxin and Furan Control can now be accomplished using a Donaldson® Torit® baghouse equipped with GORE® REMEDIA® catalytic filter bags. This can provide the economical solution you’ve been searching for! Donaldson has combined advanced dust control with catalytic chemistry technology, to produce one simplified system that:

Removes and destroys up to 99% of the dioxins and furans.
Requires minimal maintenance.
Provides the lowest cost of ownership.

Self-Cleaning Collector with Continuous Filtration

Donaldson Torit baghouses are self-cleaning dust collectors providing continuous filtration in a compact design. They are modular, allowing for flexible design, even in restricted spaces.

GORE® REMEDIA® Catalytic Filter Bags

nside the collector, the GORE® REMEDIA® catalytic filter bags are made of an expanded polytetrafluoroethylene (ePTFE) membrane laminated to a catalytic felt substrate that filters and destroys up to 99% of the dioxins and furans.

AST Canada Dioxin & Furan Abatement solutions provide:

Baghouse collectors configured to your needs
Filter bags that help destroy dioxins and furans
Local support from our engineers

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.

How GORE REMEDIA Filter Bags Work

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.

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.

Features & Benefits

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 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
