The microalga C. vulgaris, grown on the WE showed Cmax (270,009 cells ml1), lmax (0.53 d1) in the smaller wastewater concentration added to the cultivation medium (5.0 and 8.5%), while larger COD removals (69.25 and 69.90%) and the largest colour removals (75.68%) were obtained using the moderate waste water concentration in the cultivation medium Thus the cultivation of C. vulgaris in WE demonstrated the capability of biomass production, colour and COD removal; therefore this microalga can be an alternative to assist in the textile culture effluent treatment, reducing the environmental impact caused by their pollutants.
The algal biomass generated may be useful as feedstock, fertilizers or for biofuel production.
