The brand-new port treats odor problems with Nodora catalytic material air filter
Introduction.
This time, we are taking on a recently opened terminal for ro-ro (roll-on/roll-off, ships designed to transport wheeled cargo such as cars, trucks, buses, railroad cars etc.) and container ships in one of Sweden’s many ports.
The terminal was opened in May 2020, south of the Stockholm region.
The problem.
Ships docking into the port empty their septic tanks into a pump pit in the port’s pumping station. As the pump pit is filled, the large quantities of wastewater start to emit unpleasant odors, which tend to cause discomfort in the surrounding area.
One of the compounds emitted in the process is H2S, which besides its strong unpleasant smell reminiscent of rotten eggs, is also toxic to humans.
The solution.
And so, the company who owns the port turned to Mellifiq for a solution in order to tackle the odor issues posed by the pumping station. We had previously delivered a successful solution to another one of their ports.
We at Mellifiq were once again more than willing to deliver, install and commission a solution for H2S removal at the pumping station. The Mellifiq delivery consisted of a Nodora CAT filter module containing catalytic material; this solution was installed and commissioned inside the pumping station.
This is how the removal process works: as the pump pit is filled with wastewater, and the resulting odorous compounds are emitted, the air is treated before it is released into the atmosphere. The air is funneled through a ventilation duct at the top of the pit with the help of a fan. It then passes through the Nodora filter module, where it reacts with the catalytic material that in turn breaks down H2S. Finally, the treated, odorless air is released into the atmosphere.
Evaluation.
Our systems ensure a complete H2S removal in industrial applications of almost any flow, this case included.
In addition to the air treatment solution, we complemented our installation with fan and ducting, in accordance with the Swedish ABT06 standard.
