Sar, Taner; Marchlewicz, Ariel; Harirchi, Sharareh; Mantzouridou, Fani; Hosoglu, Muge Isleten; Akbas, Meltem Yesilcimen; Hellwig, Coralie; Taherzadeh, Mohammad J. (Elsevier, 2024)Industrial wastewater, often characterized by its proximity to neutral pH, presents a promising opportunity for fungal utilization despite the prevalent preference of fungi for acidic conditions. This review addresses this ... -
Salinity affects nitrate removal and microbial composition of denitrifying woodchip bioreactors treating recirculating aquaculture system effluents
von Ahnen, Mathis; Aalto, Sanni L.; Suurnäkki, Suvi; Tiirola, Marja; Pedersen, Per Bovbjerg (Elsevier BV, 2019)This study investigated the effect of salinity on microbial composition and denitrification capacity of woodchip bioreactors treating recirculating aquaculture system (RAS) effluents. Twelve laboratory-scale woodchip ... -
Removal of Ammonium Ions from Aqueous Solutions Using Alkali-Activated Analcime as Sorbent
Runtti, Hanna; Sundhararasu, Elavarasi; Pesonen, Janne; Tuomikoski, Sari; Hu, Tao; Lassi, Ulla; Kangas, Teija (MDPI AG, 2023)Five alkali-activated analcime (ANA) sorbents (ANA-MK 1, ANA 2, ANA 3, ANA-MK 4, and ANA-MK 5) were developed for ammonium (NH4+) ion removal. Acid treatment and calcination were used as pre-treatments for analcime, and ... -
Filtration of Nordic recirculating aquaculture system wastewater : Effects on microalgal growth, nutrient removal, and nutritional value
Calderini, Marco L.; Stevčić, Čedomir; Taipale, Sami; Pulkkinen, Katja (Elsevier, 2021)Microalgal bioremediation of recirculating aquaculture system (RAS) wastewater represents an alternative for wastewater treatment with the potential to generate valuable biomass. This study evaluated the effects of removing ... -
Efficiency of Daphnia magna in removal of green microalgae cultivated in Nordic recirculating aquaculture system wastewater
Stevčić, Čedomir; Pulkkinen, Katja; Pirhonen, Juhani (Elsevier, 2020)The increase of global aquaculture production has boosted the development of recirculating aquaculture systems not only because they reduce water use but also provide opportunities for waste management and the use of ...
