What type of odour control system is effective in the long run? It is a common question asked by design engineers in water and sewage treatment plants. Sewage treatment plant odour control is an important issue that should be addressed at the earliest.
Interestingly, choosing an odour control unit is comparable to selecting
a car in many ways. This is because you have an array of options to choose
from. Moreover, each odour control system comes in varied types to address
different odour-causing substances.
However, selecting and deploying a system that works effectively always
remains a challenge. Let’s take a glance at some top factors to consider while
choosing an odour control unit.
The Type of Technology
offered in Wastewater Treatment Plant Odour Control
There are a plethora of proven odour control technologies in sewage and
water treatment plants. The most common technology platforms are:
ü
Chemical scrubbing system
ü
Biological oxidation system
ü
The activated carbon
adsorption system
Out of all these technologies, activated carbon or charcoal is one of
the most effective ones. Activated carbon-based odour control systems are
pretty effective in removing foul odours from the confined areas.
The surface area of the activated carbon allows the media to adsorb
odour causing organic compounds effectively. Activated carbon exhibits
regenerative capabilities, which ensure lower operational costs for
organisations.
It is worth mentioning here that activated carbon is popular in treating
a variety of common odours. Carbon can neutralise odours from mould, human
waste, and volatile organic compounds.
Don’t undermine the
Significance of Air Exchange Factors
When opting for an odour control system, you should be aware of air
exchange factors. Air exchange factors play a vital role in determining the
unit’s overall capacity. A large majority of regional municipalities have set
clear agendas on the air exchange factors.
In the case of inlet work, you should consider an air exchange factor in
the range of 12-15 of the total air volume. On the other hand, for sludge
treatment, the air exchange factors should be 6-12 of the entire air volume.
But note that the air exchange factor relies on a wide variety of aspects like
aerated tanks, ventilation, etc.
Operational Cost is a
Crucial Factor
While investing in an odour-controlling unit, you should always consider
its operational cost. While investing in an odour control unit, many plant
owners tend to analyse only the capital cost. A large majority of plant owners
don’t give much importance to operational expenses.
But remember that operational costs can evolve as a serious issue if not
addressed properly. Plant owners usually tend to ask how
to remove smell from sewage treatment plant without considering
operational expenses.
That’s why you need to communicate clearly with the manufacture of the
odour control unit to ascertain operational costs. In case you are new to the
industry, asking the experts will always help. At times, the manufacturers
provide comprehensive maintenance services too for odour control units.
An odour control unit is an integral part of a wastewater and sewage
treatment plant. The requirements of each plant greatly vary when compared to
others. That’s why you should take a proactive approach while deploying odour
control units at your plant.
