Title

STUDY OF CAPABILITY OF ZEBRA MUSSEL (DREISSENA POLYMORPHA) IN NITRATE AND PHOSPHATE INDIRECT REMOVAL FROM URBAN WASTEWATER

Pages

  69-76

Abstract

 Zebra mussel (Dreissenidae polymorpha) is capable of filtering Great volumes of water due to its high population density. In this study, Nitrate and PHOSPHATE REMOVAL capability of 3 shell masses (20, 40, and 60 gr) in URBAN WASTEWATER was investigated based on filtering rate measurements (using simultaneous phytoplankton, chlorella, and Scenedesmus cultures) and indirect absorption of nitrate and phosphate in open and closed systems with 3 to 10 replications. Open and closed systems showed a positive correlation between shell weights and Nitrate and Phosphate filtration rates (R2=0.99) but a negative correlation between influent Nitrate and Phosphate concentrations and their filtration rates (R2=0.97). Increasing of shell weights in the open system resulted in absorption rates of 0.08-0.2mg.1-1 of the shell dry weight for Nitrate and 0.02-0.04 mg.1-1 for Phosphate. In the closed system, these rates were 0.03-0.11 mg.1-1 of the shell dry weight for Nitrate absorption and 0.01-0.02 mg.1-1 for Phosphate.These results show that shell masses have a low nitrate and PHOSPHATE REMOVAL efficiency, especially in the case of phosphate, and they can not be, therefore, recommended for URBAN WASTEWATER treatment.
