• Raudan talteenotto FePO4-jätevesilietteestä neste-nesteuutolla 

  Larsson, Sylva (2021)

  Kirjallisessa osiossa perehdyttin fosforin erottamiseen jätevesilietteestä sekä raudan talteenottoon neste-nesteuutolla. Kokeellisessa osiossa tutkittiin valitun uuttosysteemin toimivuutta Fe(III):lle ja optimoitiin ...

• Purification of recovered phosphoric acid by extracting aluminium with di-2-ethylhexyl phosphoric acid 

  Reuna, Sini; Väisänen, Ari (Springer Science+Business Media; Institute of Chemistry, Slovak Academy of Sciences, 2022)

  The extraction of aluminium from dilute phosphoric acid with di-2-ethylhexyl phosphoric acid (DEHPA) was optimized using response surface methodology. The optimization was based on the experimental three-level central ...

• Use of Calcined Dolomite as Chemical Precipitant in the Simultaneous Removal of Ammonium and Phosphate from Synthetic Wastewater and from Agricultural Sludge 

  Pesonen, Janne; Myllymäki, Pekka; Tuomikoski, Sari; Vervecken, Gwen; Hu, Tao; Prokkola, Hanna; Tynjälä, Pekka; Lassi, Ulla (MDPI AG, 2019)

  Phosphorus as phosphate and nitrogen as ammonium or nitrate are the main nutrients in wastewaters and agricultural sludges. They runoff easily to waterways and cause eutrophication in water bodies. However, ammonium and ...

• Discharge management in fresh and brackish water RAS : Combined phosphorus removal by organic flocculants and nitrogen removal in woodchip reactors 

  Kujala, Kukka; Pulkkinen, Jani; Vielma, Jouni (Elsevier, 2020)

  The current study combined P and N removal using organic flocculant chemicals and woodchip bioreactors in both freshwater and brackish water (7 ppm) recirculating aquaculture systems (RAS). The use of carbon (C) containing ...
