COD and nutrient removal from urban effluent by desmodesmus subspicatus
The aim of this research was to evaluate the heterotrophic growth and removal of COD and nutrients (nitrogen and phosphorus) of green microalgae Desmodesmus subspicatus from domestic wastewater collected in pilot plant of treatment and water reuse of the CCA/UFSCar.

| description | The aim of this research was to evaluate the heterotrophic growth and removal of COD and nutrients (nitrogen and phosphorus) of green microalgae Desmodesmus subspicatus from domestic wastewater collected in pilot plant of treatment and water reuse of the CCA/UFSCar. The results showed maximum specific growth rates of 0.084 h????1, with biomass concentrations of 1000 mg L????1 in 24 hours of the experiment. Due to the chemical content of the sterilized effluent, both the organic matter as nitrogen are limiting to microbial growth. However, for COD above 200 mg L????1, there was a high conversion of organic matter into biomass. These results suggest the feasibility of microalgae in one of the stages of suitability for agricultural reuse of domestic wastewater. |
