Microalgae Growth on Anaerobic Digestate in Raceway Systems
Hande Ermiş
Join us for a seminar by our visitor Hande Ermiş, PhD student at the Department of Environmental Engineering at Istanbul Technical University (Turkey). Hande is visiting our ALG-AD group and she is interested in algal pigments and the use of micro-algae for bioenergy production.
Anaerobic digestion is one of the most common methods used to generate energy from renewable sources. On the contrary of the benefit of the use of anaerobic liquid digestate effluent, like soil conditioning in agriculture while reducing the cost of the logistics; the characteristics of the digestion effluent can cause phytotoxic effects in plants, eutrophication of water bodies and groundwater pollution, due to the high concentrations of ammonia and phosphorus in the anaerobic liquid digestate. Therefore, the application to agricultural land without treatment may constitute a risk, thus solutions for targeting both reducing adverse effects and increasing product values by valorization should be followed. Microalgae is one of the promising candidate to recover nutrients from anaerobic liquid digestate by assimilating nitrogen and phosphate into their biomass. The results clearly indicate that anaerobic digestate can be used as a nutrient-rich cultivation medium for microalgae with high growth rates despite the fact that liquid digestate is not the ideal growth media for microalgae due to its high ammonia content, dark color, and particulate matter. In this talk, I would like to demonstrate that coupling of microalgae growth with liquid digestate treatment is an economical and ecologically friendly technology for cheap biomass production for further valuable applications in open raceway systems.
Hope to see many of you - everyone most welcome to attend!
