4.3 Odour Control Systems
|
With heightened awareness of the potential problems associated with maladours from industrial and municipal processes comes an incumbent responsibility on the generators of these odours to control their emission to the atmosphere.
CPL Carbon Link provide a comprehensive range of abatement equipment utilising dry and wet scrubbing techniques, either independently or in combination to achieve the most effective control system. |

Odours are perceived from a wide range of processes and are derived from a broad range of chemical types. In order to treat this variation different media and technologies are implemented.
For instance, where high levels of hydrogen sulphide are present, the use of catalytic iron filtration media is used to reduce the concentration of the odourous compound to allow the effective use of activated carbon to be achieved. This measure ensures optimum use of the activated carbon to prolong its life and ensure that rigorous discharge consent limits can be attained. |
|
The activated carbon used is determined in relation to the nature of the odourous compound present and can be supplied in the form of either a standard untreated grade, or a chemically impregnated type for enhanced loading capacity and removal efficiency. Where dry scrubbing methods are not suitable, due to process constraints for example, wet scrubbing methods can be implemented. Single or multiple stage stripping towers can be used to treat mixed contaminant air streams in a number of steps. Full chemical addition equipment is provided that can be automated to reduce the need for operator supervision. |
