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. Shivas, 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.

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.
The application of Shivas equipment offers a number of advantages.
Amongst these are :
- Use of multiple step abatement solutions
- Media optimisation methodologies
- In-house design and proving of abatement technologies
- Combination process solutions using a variety of technologies to
achieve odour reduction
- Extended design capability for ancillary items and abatement plant
