Removal of nitrate, nitrite, ammonium and phosphate ions from water by the aerial microalga Trentepohlia aurea

The feasibility of using the aerial microalga Trentepohlia aurea to remove nitrate, nitrite, ammonium, and phosphate ions from nutrient-rich wastewater was studied. T. aurea has a high tolerance to severe conditions (desiccation and high temperatures). When this alga was cultured with very high ammo...

More Information
Summary:The feasibility of using the aerial microalga Trentepohlia aurea to remove nitrate, nitrite, ammonium, and phosphate ions from nutrient-rich wastewater was studied. T. aurea has a high tolerance to severe conditions (desiccation and high temperatures). When this alga was cultured with very high ammonium, nitrate, nitrite, and phosphate ion concentrations, it showed relatively high growth and nutrient removal rates. Removal rates are discussed. T. aureacould potentially be used for wastewater purification.
