The new Norvik Port treats odor problems with Nodora catalytic material air filter
Stockholm Norvik Port is 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. The terminal was opened on May 27, 2020, in Nynäshamn, south of the Stockholm region.
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, large quantities of wastewater 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 of rotten eggs, is also toxic to humans.
To tackle the issue posed by pumping station odors, Stokcholms Hamnar AB, the owner of the port, turned to Mellifiq for a solution.
Since we had previously successfully delivered a similar H2S removal solution for Stockholms Hamnar AB, namely Masthamnen, the harbor in central Stockholm, the company turned to Mellifiq for a solution to tackle the odor issues posed by the pumping station.
Thus, Mellifiq was once again chosen to deliver, install and commission a solution for H2S removal at the pumping station, this time in the Norvik Port. The Mellifiq delivery consisted of a Nodora CAT filter module containing catalytic material, which was installed and commissioned inside the pumping station.
As the pump pit is filled with wastewater, and the resulting odorous compounds are emitted, the air must be 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, in order to pass through the Nodora filter module, where it reacts with the catalytic material that breaks down H2S. Finally, the treated, odorless air is released into the atmosphere.
Our systems ensure complete H2S removal in industrial applications, for almost any flow. In addition to the air treatment solution, we complemented the installation with fan and ducting, in accordance with the Swedish ABT06 standard.
