Algae for water treatment and Biofuel production (Bioenergi genom vattenrening)
Collaboration partners Hammarby Sjรถstadsverk and Clear Water Energy Nordic AB (CWE Nordic) Summary The aim of this project is to investigate how algae can be utilized in order to reduce the amount of energy (e.g. for aeration) and chemicals used in conventional wastewater treatment. The tests with algae for water treatment is also examined regarding the production of biomass that may be suitable for biogas production. The system at Sjรถstadsverket consists of shallow ponds. In a full-scale the algae treatment may replace parts of the traditional treatment processes or it may be used for complementary treatment of the effluent water. The project at Hammarby Sjรถstadsverk is aimed to investigate how different conditions and loads will effect the treatment efficiency and the biomass. Further, the biogas potential of the produced biomass is examined. The project will also include tests about the cleaning effects of different compounds that the system was not originally designed for, such as medical compounds. CWE Nordics seeks open minded collaborators in the field of gas yield optimization. This may include different treatment steps after harvesting. www.sjostadsverket.se
