• Does the freshwater mussel Anodonta anatina remove the fish pathogen Flavobacterium columnare from water? 

  Hajisafarali, Mahsa; Aaltonen, Sari; Pulkkinen, Katja; Taskinen, Jouni (Springer, 2022)

  Global decline of freshwater mussels (Unionoida) is threatening biodiversity and the essential ecosystem services that mussels provide. As filter-feeding organisms, freshwater mussels remove phytoplankton and suspended ...

• Microbiome response to foam fractionation and ozonation in RAS 

  Aalto, Sanni L.; Syropoulou, Elisavet; de Jesus Gregersen, Kim João; Tiirola, Marja; Bovbjerg Pedersen, Per; Pedersen, Lars-Flemming (Elsevier BV, 2022)

  Efficient water treatment is required to maintain high water quality and control microbial growth in recirculating aquaculture systems (RAS). Here, we examined the effects of two treatment methods, ozonation and foam ...

• The effects of different combinations of fixed and moving bed bioreactors on rainbow trout (Oncorhynchus mykiss) growth and health, water quality and nitrification in recirculating aquaculture systems 

  Pulkkinen, Jani T.; Eriksson-Kallio, Anna M.; Aalto, Sanni L.; Tiirola, Marja; Koskela, Juha; Kiuru, Tapio; Vielma, Jouni (Elsevier BV, 2019)

  The effect of bioreactor design on nitrification efficiency has been well studied, but less is known about the overall impacts on water quality. Besides nitrification, submerged fixed bed bioreactors (FBBR) trap fine solid ...

• Lignin recovery from spent alkaline pulping liquors using acidification, membrane separation, and related processing steps : A Review 

  Hubbe, Martin A.; Alén, Raimo; Paleologou, Michael; Kannangara, Miyuru; Kihlman, Jonas (North Carolina State University, 2019)

  The separation of lignin from the black liquor generated during alkaline pulping is reviewed in this article with an emphasis on chemistry. Based on published accounts, the precipitation of lignin from spent pulping liquor ...

• Comparison of three unionid mussel species in removing green microalgae grown in recirculating aquaculture system effluent 

  Julkunen, Ville; Stevčić, Čedomir; Pirhonen, Juhani; Pulkkinen, Katja (Springer Nature, 2024)

  Global increase in aquaculture production has created a need to reduce its environmental impacts. Nutrients could be recycled especially at land-based recirculating aquaculture systems (RAS) by cultivating green microalgae ...
