Odour Control is currently the subject of much debate both in Government and in the business community. This increasing awareness, along with tightening legislation, has compelled both industry and commerce to identify, source and implement a range of solutions that are designed to combat this issue.
The pivotal role of activated carbon in the control of odour and fumes is well recognised, and in spite of the launch of a range of new technologies, the powerful adsorption capabilities and relatively low cost of activated carbon has enabled it to retain its position as a major player within the filtration industry.
Activated carbon is manufactured from coal, coconut shell and wood. The processing of the raw carbon at temperatures of between 200-300oC, is designed to remove moisture and any Volatile Organic Compounds. This creates a char which is then heated to between 800 – 1000oC, in an atmosphere of steam. This is known as the activation stage, as it is when the high surface area and pore network is created, to give the resulting activated carbon its high absorbency, and adsorption capability. The activated carbon is then made into a powder, granular and as extruded pellets. The loose activated carbon media is held in place by a filter frame which is commonly referred to as a carbon filter.
Carbon filters are increasingly specified by consulting engineers when there is requirement to control or prevent any issues arising in respect of odour or fumes in their new build projects. There are many applications where carbon filters play an important role. For example kitchen ductwork specialists choose carbon filtration for controlling odour in their commercial and domestic kitchen extract systems. For liquid phase applications such as sewage treatment plants and holding tanks, activated carbon plays a crucial part in the adsorption of smell and fumes. Recent tightening of planning conditions, has also led to an increased demand for activated carbon to control atmospheric pollution at new build projects in densely populated urban environments.
