The Use of Flocculation as a Preconcentration Step in the Microalgae Harvesting Process. [PDF]

open access: yesPhysiol Plant
ABSTRACT Flocculation is a widely utilized separation technique in colloid chemistry, the chemical industry, and wastewater treatment. However, its application in microalgal biomass production and downstream processing remains limited. Biomass harvesting represents a significant cost factor in large‐scale microalgae production, with the separation of ...

The use of natural organic flocculants for harvesting microalgae grown in municipal wastewater at different culture densities

open access: yesPhysiologia Plantarum, Volume 173, Issue 2, Page 536-542, October 2021., 2021
Abstract Harvesting microalgae from liquid culture is a difficult issue to solve and is most commonly done through settling. However, settling is a slow process on its own and generally needs to be induced chemically or by introducing stress to the culture.

Sustainable production of microalgae biomass for biofuel and chemicals through recycling of water and nutrient within the biorefinery context: A review

open access: yesGCB Bioenergy, Volume 13, Issue 6, Page 914-940, June 2021., 2021
Studies on recycling of various streams for water and nutrient supply in microalgae cultivation are encouraging. However, presence and subsequent accumulation of organic and inorganic molecules produced during microalgae growth or generated during post‐processing can limit the long‐term recycling potential of these streams.
