In many areas of industry and the military, high temperature ceramic filters form an essential part of reducing or entirely eliminating waste. In today's environmentally aware society, causing as little damage to the land, the air and the sea is not only desired by the majority of the public - but is essential in protecting sensitive environments.
Back in 2007 when the UK Government was handling the Foot and Mouth outbreak, filters formed an essential part of the OTMS bovine carcass rotary incinerator, used to dispose of the huge number of cow carcasses. Protecting the environment was a priority, especially since such a large job would put huge pressure on the entire process. The quick and hygienic disposal of the infected carcasses reduced the risk of the virus being passed on to other livestock or animal life.
In the general area of carcass incineration too, filters play a crucial part in efficient, high speed - and above all safe disposal of such farm waste.
In the military as well, filters have formed an essential part of dealing with various wastes. On the Royal Navy's amphibious assault ship HMS Ocean, a system to deal with waste was installed which included an incinerator along with filters. As this installation is on board a naval vessel, there are not a great many details available, but the system represents the first of its kind fitted in to such a ship. Strict laws prevent ships dumping waste at sea, so using this incineration/filters system was essential for the Royal Navy.
The Waste Incineration Directive (WID) is the piece of legislation that ensures that all types of organisation keep their pollution levels to an extremely low level - or eradicate them altogether. It was introduced by the European Union in December 2000, and all member states must comply.
Such filters are also used in the production of nuclear fuels, where they reduce costs and risk of environmental impact. As it is also a very sensitive area, information is fairly restricted concerning the filters and their use, but they have become integral in the safe production of nuclear power.
The world of aluminium recovery and production too has benefitted from the use of high tech filters - benefitting the workers and the environment surrounding these facilities. Oily fumes generated by the process of smelting oily swarf (this is the debris from metal work facilities, which could be described as chippings or shavings) in an induction furnace is one of the reasons such a system is installed, filtering these fumes out. Swarf and its disposal is a drawn-out but necessary process, as these shavings can be dangerous. The main risk is posed by the fact that they are very sharp and can easily penetrate human skin. Disposal involves the use of centrifuges. Such installations, using these high tech filters, are found across the globe, reducing environmental impact as well as risk to associated workers.
Wherever they are manufactured and implemented around the world, high temperature ceramic filters provide an effective means to reduce the impact industry makes on the countryside, the air and the people who work in these areas.
