Sustainable algal biomass products by cultivation in waste water flows
Algae are predicted to play an important role in tomorrow’s bioeconomy. The technical goal of the project was to develop enhanced algal cultivation processes utilising waste flows and to increase the overall material and energy efficiency of algal processing for biodiesel and biogas production. The project produced new knowledge on the boundary conditions for cost efficient algal cultivation an...
متن کاملMicroalgae Cultivation on Anaerobic Digestate of Municipal Wastewater, Sewage Sludge and Agro-Waste
Microalgae are fast-growing photosynthetic organisms which have the potential to be exploited as an alternative source of liquid fuels to meet growing global energy demand. The cultivation of microalgae, however, still needs to be improved in order to reduce the cost of the biomass produced. Among the major costs encountered for algal cultivation are the costs for nutrients such as CO₂, nitroge...
متن کاملPhosphate and nitrate removal from municipal wastewater by algae Scenedesmus obliquus cultivation and production of algal biomass
Nitrate and phosphate are abundant in urban wastewater. We evaluated the efficiency of nitrate and phosphate removal from wastewater by Scenedesmus obliquus and its use as a medium for Scenedesmus obliquus. Samples were collected from the effluent of central wastewater treatment in Gorgan. This experiment was done by 3 treatments and 6 replications that effluent with 100%, 50% and 0% were dilut...
متن کاملUtilization of lipid extracted algal biomass and sugar factory wastewater for algal growth and lipid enhancement of Ettlia sp.
The present study assessed the use of hydrolysate of lipid extracted algal biomass (LEA) combined with the sugar factory wastewater (SFW) as a low cost nutrient and a carbon source, respectively for microalgal cultivation. Microalgal strain Ettlia sp. was both mixotrophically and heterotrophically cultivated using various amounts of hydrolysate and SFW. The culture which was grown in medium con...
متن کاملToward facilitating microalgae cope with effluent from anaerobic digestion of kitchen waste: the art of agricultural phytohormones
BACKGROUND Although numerous studies have used wastewater as substitutes to cultivate microalgae, most of them obtained weaker algal viability than standard media. Some studies demonstrated a promotion of phytohormones on algal growth in standard media. For exploiting a strategy to improve algal biomass accumulation in effluent from anaerobic digestion of kitchen waste (ADE-KW), the agricultura...
