FILTRATION CHALLENGES Tetratex filter media can enhance the performance of your fabric filter by utilizing surface filtration technology as opposed to traditional depth filtration methods. ATetratex Reduced Emissions Near-zero emissions can be achieved due to the microporous structure of the membrane. Particulate is collected on the surface, reducing environmental emissions within regulatory limits. Significant savings in power consumption can be achieved by maintaining required airflow at a reduced filter DP Surface filtration principles inhibit particle migration resulting in increased cleaning efficiency....

DEPTH VS SURFACE FILTRATION There are two key functions of a solid/gas filter – the capture of dust particles in the gas stream and the maintenance of gas flow through the media employed. For any filter media to operate effectively, it must satisfy on both these counts. For collection to be effected, any individual particle in the gas stream must be slowed, intercepted and collected on or within the filter media. In the case of conventional filter fabrics the interstices between the fibers within the structure of the media are often considerably larger than the particles to be collected. So,...

TETRATEX REDUCES EMISSIONS AT GERMANY BIOMASS POWER PLANT Tetratex High Efficiency Woven Glass filter media has helped to improve filter bag life and reduce environmental emission levels. Due to technical issues in the process, the baghouse was not in use for a year, after which time the only sleeves still intact in the filter chambers were the #6255 Tetratex Ultra High Efficiency bags; the alternative PPS bags had become tarnished and stressed. • Operating Temperature: 500°F/260°C Peak • Total Filtration Area: 5085ft2/472m2 Results • 6 year bag life to date • Achievement of 14 MW/h, as a result...
