Dual role of Chlorella vulgaris in wastewater treatment for biodiesel production: Growth optimization and nutrients removal study
The environmental footprint for microalgae based biofuel can be reduced by coupling the microalgae cultivation with wastewater treatment. In the present study, the nutrients source for microalga Chlorella vulgaris was replaced by municipal wastewater from wastewater treatment plant located at USM En...
