Chlorella’s wastewater cleaning ability confirmed

Chlorella vulgaris algae grown in waste water

Environmental engineers at the University of Arkansas have discovered that Chlorella vulgaris, a single-celled fresh water algae species, effectively removes pollutants from wastewater even at fluctuating levels, making it an effective tool for wastewater treatment.

The study, published recently in Water Environment Researchindicates that Chlorella vulgaris continues to remove harmful elements like nitrogen and phosphorous from wastewater even after one type of pollutant is depleted. Some algae require both nitrogen and phosphorous to be present to function, which can limit its effectiveness in wastewater treatment.

“One of the factors that significantly impacts algal wastewater treatment is nutrient availability,” said Wen Zhang, associate professor in the Department of Civil Engineering. “What is the ideal range of nitrogen-to-phosphorous mass ratio for algal growth? Because previous research failed to identify this, the efficacy of algal treatment has been difficult to predict or optimize.”

Wastewater quality fluctuates dramatically, which makes it difficult to initiate and maintain algae growth for treatment. Dr. Zhang’s study now shows that Chorella vulgaris could survive even in the absence of either nutrient.

Wen Zhang is an associate professor in the Department of Civil Engineering at the University of Arkansas.

Dr. Zhang worked with John Chamberlin, doctoral student in the environmental dynamics program, and Kristen Harrison, an undergraduate honors student in the Department of Crop, Soil, and Environmental Sciences.

The researchers grew the algae in synthetic wastewater under several nutrient-limiting conditions and in effluent from two wastewater treatment plants. They found that Chorella vulgaris removed both nitrogen and phosphorous after secondary wastewater treatment, in all levels or ratios of nutrients tested.

The research is funded by the Arkansas Biosciences Institute and the University of Arkansas Doctoral Academy.
