Microalgae cultivation integrated into agro-industrial wastewater treatment

Indigenous Microalgae-activated Sludge Cultivation System for Wastewater Treatment

“Everything is everywhere, but the environment selects the best duo’’; natural selection holds the key to the relationship between the micro-algal communities in Lake Mälaren and the activated sludge organisms in the municipal wastewater of Västerås. Interest in microalgae-based activated sludge wastewater treatment has been increasing in recent decades as a way to meet the demand for sustainab...

Microalgae 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...

Microalgae Cultivation in Wastewater for Nutrient Removal

Wastewater is the spent or used water containing dissolved or suspended solids such as pollutants and microbes, including nutrients. The wastewater discharged into the water bodies are hazardous to environment and cause various health problems in human beings. Eutrophication is one such major environmental problem caused due to the discharge of nutrient rich wastewater into the nearby water bod...

Investigation of microalgae cultivation and anaerobic codigestion of algae and sewage sludge for wastewater treatment facilities

Microalgae cultivation on wastewater digestate: β-estradiol and 17α-ethynylestradiol degradation and transformation products identification.

Selenastrum capricornutum and Chlamydomonas reinhardtii were tested for possible biodegradation of the hormones β-estradiol (E2) and 17α-ethinylestradiol (EE2) when cultured in anaerobic digester centrate (ADC). Neither ADC nor the hormones had a negative or toxic effect on the microalgae growth but enhanced it. E2 and EE2 biodegradation was evaluated under different culture conditions. After 7...
