      Daneshvar, Ehsan; Sik Ok, Yong; Tavakoli, Samad; Sarkar, Binoy; Shaheen, Sabry M.; Hong, Hui; Luo, Yongkang; Rinklebe, Jörg; Song, Hocheol; Bhatnagar, Amit (Elsevier, 18.02.2021)
      The aim of this review is to provide insights into the upstream processing of microalgae, and to highlight the advantages of each step. This review discusses the most important steps of the upstream processing in microalgae ...

    • Purification efficiency of natural freeze crystallization for urban wastewaters 

      John, Miia; Häkkinen, Antti; Louhi-Kultanen, Marjatta (Elsevier, 21.11.2019)
      Human population growth and urbanization are aggravating water quality problems in many regions, and wastewater volumes and quantities of pollutants are increasing due to greater industrial and urban activity. Thus, it is ...

    • Purity and mechanical strength of naturally frozen ice in wastewater basins 

      John, Miia; Suominen, Mikko; Sormunen, Otto-Ville; Hasan, Mehdi; Kurvinen, Emil; Kujala, Pentti; Mikkola, Aki; Louhi-Kultanen, Marjatta (Elsevier, 15.11.2018)
      A fairly clean ice cover can form over a contaminated water pond when the air-cooled surface of water freezes and impurities are efficiently expelled to the remaining water underneath. Natural freeze crystallization has ...

    • Systematic study on sulfate removal from mining waters by electrocoagulation 

      Mamelkina, Maria A.; Tuunila, Ritva; Sillanpää, Mika; Häkkinen, Antti (Elsevier, 28.01.2019)
      The mining industry is known to be a major producer of sulfate-rich waters that are harmful to aquatic systems, accelerate acid mine drainage formation and hinder the reuse and recycling of process water. In recent years, ...
