OMBYGGNADER AV BROMMA RENINGSVERK ÅREN 1980-1984 / Bromma Wastewater Treatment Plant - Conversions during the Period 1980-1984
Bromma Wastewater Treatment Plant, which serves the western part of Stockholm, comprises two units: the Åkeshov plant and the Nockeby plant. Today, mechanical and chemical treatment takes place at Åkeshov, accompanied by sludge treatment, while the biological treatment is carried out at the Nockeby plant. At the beginning of the 1980’s considerable conversion and extension work was carried out at the two plants, the total investment amounting to approximately SEK 110 million. The major costs were attributable to the extension of the biological treatment at Nockeby. Among other items, mention can be made of the new sludge dewatering plant in Bromma, the change in reagents from ferrous sulphate in monohydrate form to heptahydrate, and the construction of the new main building and new central boiler plant. Bromma Wastewater Treatment Plant has a capacity of 160,000 m3/d and the population served is in the region of 246,000.
