Käppala renseanlegg Mekano opphengssystem leveranse

Ögländ System AB delivers to Sweden's third largest wastewater treatment plant

We delivered approximately 150 support systems, consisting of Mekano® Channel 100-2-T2, which builds upon our Mekano® system, plus a special solution developed by the consultation firm EVT Umeå AB.

A new sludge-digestion compartment was constructed at Käppala wastewater treatment plant, in order to deal with increasing amounts of wastewater. At the same time, a new facility for high-flow wastewater was constructed to keep up with future treatment requirements. The plant already receives wastewater from eleven municipalities in Storstockholm, which equates to about half a million people.

NCC is the contractor for this project called R300 and they decided to use Øglænd System’s support solutions in the entry tunnel and in other tunnels to support all disciplines. 

A welded solution for all support systems was initially specified. However, after Ögländ System AB showed how our products were more cost effective, quicker and easier to install, the contractor and facility chose to use Øglænd System’s products in the tunnels where a welded solution had not already been ordered.

“We used Øglænd System’s products in a previous project, and when I came to this project there was another solution specified, but it was difficult to install. There are many requirements to consider with water treatment plants, which is why we chose Øglænd Systems bolted solution over a welded solution. We will finish installation of the support systems this week and are very pleased with them,” Project Manager for NCC Christian Jonsson says.

The new sludge digestion compartment will work to relieve the two existing compartments. Where climate friendly biogas that can supply 100 gas fuelled busses is produced. While the high-flow facility handles situations when amounts of wastewater breaches the Käppala plant’s capacity. Considering the climate changes, this is an important environmental measure that enables faster and more thorough treatment of the water that is discharged.
