Industrial Odours: Problems & Solutions
Industrial odours
are emitted by a number of sources. It can come from pungent chemicals,
decaying matter, or industrial equipment.
The amount and
intensity of odour generated also varies according to the external environment
and the climate. For instance, a hot and humid climate increases odour
generation. Similarly, strong winds can cause the odours to spread more easily.
Foul odours become
a huge challenge and if the permitted odour levels are not maintained, the
local authorities can limit or stop all industrial activities.
It doesn't matter
if you are in the waste management, food processing industry or recycling
processes, industrial odour control is extremely crucial.
Problems arising due to industrial odours:
The odorous gases
are usually corrosive. They can have a negative impact on equipment life,
productivity, as well as the quality of life of working individuals.
Standing a bad
smell is not only disgusting but also demoralising. It makes the employees feel
sick and irritable. This also hampers the productivity of the workers.
In such an
environment, it becomes difficult to retain employees. Also, attracting new
staff becomes a tedious task.
Moreover, it also
becomes intolerable for the regular residents of the area. Complaints from the
locals lead to negative media coverage. It may also invite unwanted government
action.
You may face fines
and other punishments if a clean and healthy environment is not maintained.
This may put a mark
on the business's reputation, leading to huge financial losses.
An industrial
setting without odour control repels potential investors as well. Thus, the
growth of the industry becomes stagnant.
Odour control solutions:
A number of odour
control solutions are available suited to many different industry types.
Today, many
companies offer state-of-the-art technology to neutralise odours generated due
to industrial processes.
The equipment
includes a nozzle, an atomiser and a neutralizing spray. The neutralizing agent
is mixed with water. It actively breaks down odour-causing molecules in the
atmosphere.
Another odour
absorption technology focuses on natural methods. It relies on the power of
natural plant oils to absorb and neutralize odour molecules.
Scrubbing towers
use either water or a suitable chemical, which can be used to reduce or remove
odorous chemicals from gas streams.
Some make use of
simple absorption, using water, others may use adsorption combined with chemical
reactions like oxidation. Common scrubbing chemicals used for odour control
include sodium hydroxide and sodium hypochlorite.
For sensitive
applications, carbon adsorption can be used to reduce obnoxious odours.
Activated carbon can be utilised as a polishing stage. It is highly efficient
and is ideal in applications where low emission limits are needed.
Besides the above,
other odour control systems include:
●
Large, multi-stage chemical
Scrubbing Systems

Industrial odour
control systems help to treat odours from the air and water. This provides
clean and fresh air. Since the odour-causing gases are treated, it protects the
environment. The systems also aim at eliminating germs, viruses, moulds, etc.
