Catalytic Ceramic Filters

Advanced Multi-Pollutant Ceramic Filter Technology

A diagram illustrating the cross section of a ceramic filter. On the left of the filter is a blue arrow pointing at the filter with the text "airflow". On the right is a blue arrow pointing at the filter with the text "Dirty Air". In the middle of the filter, a light blue arrow points up and out of the filter. Below is the text "Clean Air". Around the filter are several text boxes highlighting the following features of the filter: 1) PM does not penetrate walls of the filter. 2) Particulate captured on the filter surface. 3) Nano-Catalyst embedded in the walls of the filter. 4) Process PM + SO2 Sorbent PM + NOx + Ammonia. Below the image is a caption which reads "Meets EPA Regulations".

As industries worldwide face increasing pressure to meet stringent environmental regulations, Ceramic Filter Technologies have emerged as a leading solution for advanced multi-pollutant reduction and high temperature filtration.  

With decades of experience deploying ceramic filter systems across the world, our team brings deep technical expertise and proven results. Recognized as Best Available Control Technology (BACT) in numerous industries and jurisdictions, our solutions guarantee regulatory compliance and operational excellence. 

At the heart of our proprietary systems lies CFA Cerafil® Ceramic Filters, delivering industry-leading performance across a wide spectrum of pollutants—including submicron PM, NOₓ, SO₂, VOCs, HAPs, and many more. 

Operating most effectively between 350°F (176°C) and 900°F (454°C), Ceramic Filters represent the only proven all-dry solution capable of guaranteeing the highest levels of multi-pollutant reduction—all within a single, integrated system.

Ceramic Filter Technology offers unmatched multi-pollutant control in an all-dry system—helping clients achieve and exceed regulatory thresholds while minimizing risk and lifetime costs. While different technologies serve different purposes, ceramic filters are often the most efficient and cost-effective choice across a broad range of industries. 

Particulate Matter

Achieving HEPA-like filtration efficiency (>99.99%) of submicron particulate with low and stable differential pressure, with exclusive use of CFA Cerafil® filters.  

Nitrogen Oxides (NOₓ) 

Our proprietary deNOx catalyst achieves NOₓ reduction exceeding 95%—with zero catalyst poisoning and lowest ammonia slip. This leads to no catalyst replacement for the life of the filter, and no degradation in performance.

Sulfur Dioxide (SO₂) & Acid Gases 

With our stepped SO2 management strategies, we can achieve in excess of 95% SO₂ and acid gas removal with use of dry sorbent. From single lance injection to proprietary HTCDS (High-Temperature Circulating Dry Scrubber) technologies, our designs can guarantee the most stringent requirements. 

Carbon Monoxide (CO)

With our proprietary dual NOₓ–CO catalyst, we are the only company able to achieve simultaneous CO & NOx treatment through a single system, with NOx & CO emissions reductions exceeding 90%.

Volatile Organic Compounds (VOCs) 

While VOC strategy can be complex, due to our capability to operate at high temperatures, our CCF systems have the capability to remove specific VOCs within our CCF system.  

Mercury (Hg) & Heavy Metals 

Our  ceramic filter system designs can often be part of broader emissions control strategies that include capture and stabilization of heavy metals, depending on application. 

Add-On Modular Advancements

Our CCF System is a flexible, all-dry, single-pass-through solution designed to deliver the highest levels of multi-pollutant reduction. Our continued commitment to advancement of the technology enables is to provide solutions that can achieve higher performance, lower lifetime costs, and optimized operation and maintenance. 

The Base system features CFA Cerafil Ceramic Filter elements in pre-fabricated modular housing, designed to utilize the lowest achievable ammonia and dry sorbent to meet multi-pollutant reduction—including PM, NOₓ, SO₂, VOCs, and more. 

Add-Ons:

+ CO Reduction 

Integrates CO control by incorporating blended CO and deNOₓ catalyst into the CFA Cerafil® filter element, achieving up to 90% CO reduction without adding complexity and further equipment. 

+ Advanced NOₓ Reduction 

Enhanced NOₓ removal to levels exceeding 95% using optimized system controls, precise ammonia dispersion, and advanced temperature management. 

+ Advanced SO₂ Reduction 

Integrating our proprietary HTCDS (High-Temperature Circulating Dry Scrubber) technology with CCF to achieve SO₂ and acid gas reduction exceeding 95% —the highest removal rate with lowest consumable costs from any all-dry system. 

Wide Ranging Applications

Catalytic Ceramic Filter (CCF) technology is a versatile, high-performance solution that has been successfully implemented across a wide range of industrial sectors worldwide. With over 800,000 CFA Cerafil® filters installed globally, our systems have proven their value in even the most demanding applications—offering exceptional pollutant reduction, operational efficiency, and long-term cost savings.
