Abstract
Historic effluent discharge and water-quality data analyses
from six wastewater-treatment facilities (WWTF) in
Metropolitan Atlanta indicated that the phosphorus load
discharged to the Chattahoochee River decreased by about 83
percent during the period 1988-93 because of legislated
restrictions on the use of phosphate detergents and improved
efficiencies of phosphorus removal within WWTF. The U.S.
Geological Survey recently compiled influent data for two
Cobb County WWTF. These data, when compared to effluent
data, are used as an example of percent phosphorus removal
attributed to the legislated restrictions and improved
efficiencies within the WWTF. Even though the volume of
water treated by the two WWTF increased because of
population growth, phosphorus concentrations and loads discharged
from the WWTF decreased by 91-94 percent. About
55 percent of the decrease in phosphorus concentration, and
31-33 percent of the phosphorus load occurred in the influent
and was attributed to the legislated restrictions on use of
phosphate detergents. The remaining decrease in phosphorus
concentrations and loads occurred in the WWTF and was
attributed to improved efficiencies in treatment processes.
