The worldwide olive oil sector is a strategic sector for olive oil producing countries due to olive oil nutrition and health benefits. With what is being produced of olive oil, it continues to produce wastewater with a significant environmental impact due to the high organic load and the biochemical composition of this wastewater, particularly, the presence of microbial growth inhibiting compounds such as phenolic compounds, which makes its biological treatment difficult. On other way, red mud, the main leaching r...

Conventional wastewater treatment plants (CWWTPs) play a key role in reducing the environmental impact of urban wastewater. But nowadays, this role goes even further with climate change, water scarcity, and the current energy crisis. After the thickening of the secondary sludge, a wastewater flow is generated, which is normally recirculated to the plant head for further treatment. This work aims to use secondary thickener wastewater (STW) as a culture medium for Chlorella vulgaris, Neochloris oleoabundans and Scen...
