Long-term degradation of dilute polyacrylamide solutions in turbulent pipe flow

Year: 1989

Type: article

Abstract: The long-term degradation behavior of 200 wppM polyacrylamide solution was studied experimentally in a closed recirculatory flow loop at temperatures of 7.2, 25 and 87.8/degree/C. The degradation behavior was found to be strongly dependent on temperature. The results indicate that, with flow shear similar to that encountered in practical DHC pipe flow, polyacrylamide solutions are highly effective and have a reasonable lifetime at chilled water temperature of 7.2/degree/C. 9 refs., 4 figs.
