When
Odours Control Becomes Safety Solution
For those
in the water sector the control of odours is not only an issue
of public nuisance but is now also recognised as an important
health and safety consideration. With significantly enhanced health
and safety regulations and an increasingly litigious public, this
is an area of odour control that has significant consequences.
One UK business has developed a solution to these issues that
many are describing as ‘groundbreaking’,
Probe Industries
is leading the field in this area and a recent installation of
its new odour control solution, ProActive, is seen as an important
step in tackling both the nuisance and safety implications of
malodours.
Following
a successful trial earlier this year, Probe Industries ProActive
was installed in a large waste water treatment works that served
a population equivalent of 1.5 million.
The challenges
of this installation were considerable. Hydrogen sulphide levels
around the Aquabelt of the dewatering building frequently rose
to 60ppm yet to achieve a safe working environment, levels had
to be below 3.6ppm. The works needed to install fixed monitors
and the operators had their own personal monitors to detect hydrogen
sulphide. Alarms were frequently set off as the hydrogen sulphide
levels exceeded safe limits. Maintenance of equipment was also
restricted because of the hydrogen sulphide levels within the
dewatering building.
Bob Fowler,
Probe Industries’ Technical Advisor for Sludge Treatment,
remained confident, “We robustly tested ProActive over a
long period of time and the results we were achieving were often
staggering – I was confident even at these high levels we
could meet the challenge”,
The installation
of a demonstration kit appeared to justify Bob’s confidence.
The demonstration kit on one of the Aquabelt dewatering streams
immediately eliminated all measurable hydrogen sulphide emissions
from the Aquabelt process. In fact the results were so impressive
the operating company immediately ordered the installation of
a full scale Probe ProActive dosing plant for all 5 Aquabelt presses.
To further add to the challenge the operating company wanted the
dosing plant to be fully operational within 10 working days.
Once the installation
was complete, ProActive was found to have eliminated not only
hydrogen sulphide but also the ‘cabbage smelling’
mercaptans and dimethylsulphide which remain if sludge is dosed
with permanganate. The results radically changed the working environment,
reducing costly delays in maintenance and improving the health
and safety of the workforce.
The sludge
treatment team leader highlighted the impact of this new product
‘Now that we do not have the hydrogen sulphide monitors
constantly alarming, my operators can get on with their job of
keeping the equipment clean, fully operational and dewatering
sludge’.
Evidence
of the impact of this process was also seen in a less conventional
way. Phil Rutherford, Managing Director of Probe explains, “During
a site visit one sludge plant operator showed me a silver chain
which he wore around his neck. He said that he could not wear
this chain prior to ProActive dosing because the silver went black
after a single shift, now he wears his chain all week without
any discolouration”. SOURCE
