Experts in air filtration
Filter Designs have designed and developed cleanREACT; our own range of Gas Suspension Absorbers (GSA). The GSA process is a dry desulphurisation technology, with lime as a sorbent. The process removes sulphur dioxide (SO2) by contact between the dry lime powder and the acid constituents in the flue gas. The GSA process is known for […]
Filter Designs have installed numerous gas cooling systems. Through our cleanQUENCH range, we offer quench cooling systems that are capable of cooling gases from around 1100°c, to bag filter inlet temperatures of approximately 220°c. Some of our gas cooling systems have even been installed in existing refractory-lined furnaces. These comprise of duty and standby pumps, […]
Much of our work at Filter Designs operates on processes such as aluminium and glass furnaces, pyrolysis plants and waste-to-energy systems. High temperatures of up to 1200°c mixed with impurities in the process and/or process variables can lead to sparks exiting the process into the gas treatment plant. Typically, cyclones are used pre-filter when a […]
To control quality and design flexibility, we have developed our own range of silos. As well as being used as part of larger projects, they are now available as a standalone product. Silos are primarily used by our customers as storage for the sorbent injection for acid reduction (sodium bicarbonate, hydrated lime) and for the […]
Our in-house designed cleanNOx SNCR (selective non catalytic reduction) systems / urea skids are designed to reduce the NO and NO2 in the gas stream to meet the requirements of the Industrial Emissions Directive (formerly the Waste Incineration Directive), and BREF (the EU Best Available Techniques reference documents, or “BREFs”). BREFs represent the outcome of […]
Our cleanDOSE sorbent dispensing systems are based on dosing reagents using bulk bags. They all have feeders like the cleanPAC systems, but are larger to accommodate a bulk bag. We have three types: CleanDOSE Base – here the bulk bag is lifted by forklift truck onto a membrane. The bulk bag bottom spout is opened […]
At the heart of almost everything we do is a filter. Through the years we have developed a range of filters that you can trust. Under our cleanPULSE brand, we offer 3 different filter types, all of which take out harmful particles from the environment. We have: cleanPULSE bag filters cleanPULSE cartridge filters cleanPULSE ceramic […]
PAC Dosing is the process of introducing an amount of powdered activated carbon (PAC) to reduce the heavy metals, dioxins, and furans in the gas stream that sodium bicarbonate or lime cannot remove. By accurately controlling the ‘dose rate’ of activated carbon you can: Ensure there is enough PAC to provide effective treatment Avoid unnecessary […]
We were contracted to provide 2 small Ceramic filters suitable for a small volume but with a design maximum temperature of 600°C. In addition the filters will be handling a syngas which cannot be mixed with oxygen so an alternative to compressed air would need to be used for the ‘Cleanpulse’ cleaning of the 25 Ceramic element in each of these CPC78 filters. In addition dosing of small amounts of a re-agent is required so the client also opted for a ‘Cleandose’ 25kg bag skid. Find out more about Project CAD below.
