    Abstract : There are about 700,000 on-site sewage facilities (OSSFs) in Sweden, almost a quarter of which amount only to septic tanks for sludge collection and removal, with no form of post-treatment. All these OSSFs contribute about 10 % of the total anthropogenic phosphorus (P) load from Swedish coasts to the Baltic Sea. READ MORE

  5. 19. Springs in the Central Parts of Vallentuna Municipality - traditions and threats

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Hannan Hadodo; [2017]
    Keywords : Spring; water quality; restoration;

    Abstract : Twenty springs in the central parts of Vallentuna municipality have been studied to determine their present water qualities and suggest actions that could be taken to improve the water quality and availability of the springs. The measured parameters are the water volume, the water flow, the water temperature, the pH-value, the electrical conductivity, the chloride concentration, the alkalinity and the CODMn. READ MORE

  6. 20. New technique for energy efficient CO2-separation through absorption with a sterically hindered amine

    University essay from Lunds universitet/Kemiteknik (CI)
