• Enhanced nitrogen removal of low carbon wastewater in denitrification bioreactors by utilizing industrial waste toward circular economy 

  Kiani, Sepideh; Kujala, Katharina; Pulkkinen, Jani; Aalto, Sanni L.; Suurnäkki, Suvi; Kiuru, Tapio; Tiirola, Marja; Kløve, Bjørn; Ronkanen, Anna-Kaisa (Elsevier, 2020)

  Aquaculture needs practical solutions for nutrient removal to achieve sustainable fish production. Passive denitrifying bioreactors may provide an ecological, low-cost and low-maintenance approach for wastewater nitrogen ...

• Methylophilaceae and Hyphomicrobium as target taxonomic groups in monitoring the function of methanol-fed denitrification biofilters in municipal wastewater treatment plants 

  Rissanen, Antti; Ojala, Anne; Fred, Tommi; Toivonen, Jyrki; Tiirola, Marja (Springer; Society for Industrial Microbiology, 2017)

  Molecular monitoring of bacterial communities can explain and predict the stability of bioprocesses in varying physicochemical conditions. To study methanol-fed denitrification biofilters of municipal wastewater treatment ...

• Denitrification and dissimilatory nitrate reduction to ammonium in a lake receiving wastewater effluent 

  Hasari, Miikka (2015)

  Denitrifikaatio ja DNRA (dissimilatory nitrate reduction to ammonium) ovat nitraattia pelkistäviä prosesseja, jotka yleensä esiintyvät hapettomissa olosuhteissa, kuten järvien sedimenteissä ja alusvesissä. Denitrifikaatiossa ...

• Sediment diffusion method improves wastewater nitrogen removal in the receiving lake sediments 

  Aalto, Sanni L.; Saarenheimo, Jatta; Ropponen, Janne; Juntunen, Janne; Rissanen, Antti; Tiirola, Marja (IWA Publishing, 2018)

  Sediment microbes have a great potential to transform reactive N to harmless N2, thus decreasing wastewater nitrogen load into aquatic ecosystems. Here, we examined if spatial allocation of the wastewater discharge by a ...

• Occurrence of pharmaceuticals in municipal wastewater treatment plants and receiving surface waters in Central and Southern Finland 

  Lindholm-Lehto, Petra (University of Jyväskylä, 2016)

  The presence of five selected pharmaceuticals, four anti-inflammatory drugs, diclofenac, ibuprofen, ketoprofen, naproxen, and an antiepileptic drug carbamazepine, was determined at four municipal wastewater treatment plants ...
