Controlling Emissions With Ceramic Filters

By Andrew Startin and Gary Elliott, Clear Edge Filtration |

Ceramic filters are well suited for high-temperature processes that are subject to strict emissions limits, including those for dioxins About Incineration Incineration processes are being widely used more and more to deal with the disposal of waste materials. In many countries, land filling of waste materials is not practical or desirable due to a lack of appropriate sites. Incineration has the benefit of reducing both the volume and mass of waste, thus reducing the amount of material to be disposed of. Incineration is now applied to a wide range of waste streams from high-tonnage municipal solid waste (MSW) through to the lower-tonnage specialty wastes produced by industrial processes. However, whatever the application, the imperative for the incineration process is broadly the same — a reduction in mass and volume while rendering the remaining waste material as inert as possible and, of course, producing the absolute minimum of emissions. Waste incineration, as with other industrial processes, has been the subject of ever tightening emissions legislation in recent years. Public disquiet over incineration processes and the generation of potentially dangerous emissions has subsequently, detrimentally affected the approval of…
