Activated carbon and
chemical filter medium
Gases and harmful particles are invisible and any damage is unpredictable. It is important to first clarify the situation and any presumptions. For example, is there a nuisance odour in a company or space? Has technical equipment been affected? Do people in the environment complain about bad smells? Or should government measures be taken to control toxic or harmful gases?
No business situation is the same. Variables such as the industry, local conditions, the degree and type of production or the specific use of spaces are all decisive. For this reason, the solution is never straightforward. However, one thing is for sure, CF Industrial has an effective means to arrive at a solution: activated carbon and an oxidant filter medium.
Activated carbon is a porous black material made from wood, peat, coal and coconut husks. The carbon is activated with steam or chemicals, thereby increasing the absorption force. This makes it ideal for air and water purification and for refining edible oils, sugar and other liquids.
Oxidant filter medium
The oxidant filter medium is made on the basis of aluminium oxide mixed with different binders and impregnated with potassium permanganate.
Not every situation can be solved with only activated carbon or an oxidant filter medium. Sometimes a combination of different filter media is necessary. We call this a blend. Depending on the situation, CF Industrial uses different types of blends.
A selection of common solutions
CKV-4x6 is a coarse-grained activated carbon based on bitumen. This activated carbon is generally harder than pelletised activated carbon and is lower in price. Due to their shape, they have a higher differential pressure because of the more compact filter bed. Gases that can be removed include: Organic gases, Volatile...
