Abstract:   (2753 Views)

Nitrate and phosphate are abundance in urban wastewater. To evaluate the efficiency of nitrate and phosphate removal from wastewater by Chlorella vulgaris and its use as a medium for Chlorella vulgaris, samples collected from the effluent of central wastewater treatment in the Gorgan. This experiment included 3 treatments and 6 replications that effluent with 100%, 50% and 0% were diluted. The results showed that Chlorella vulgaris could well be grown in wastewater and 100% Phosphate (group C0) and 99/37% nitrate (group C50) was removed. The highest biomass production (0/25 grams per liter), the amount of chlorophyll a (3/34 mg per liter), the number of cells (1/4 × 106 cells per ml) was observed in the group C0. Considering the results of this study, it seems that the algae can be used to remove phosphates and nitrate and algal biomass in municipal wastewater filtration systems before entering the environment. The municipal wastewater can be used as culture medium for mass production of algae.
