Effect of Sludge Retention Time in a Continuous-Flow Two-Sludge System

Article Preview

Abstract:

A continuous-flow two-sludge system was operated for efficient enhanced biological phosphorus removal. Phosphorus uptake took place solely under anoxic conditions with simultaneous denitrification in this system. Basic operating condition, namely sludge retention time was chosen as variable in order to assess its impact on the system performance. The experimental results indicated that the system could work stably and efficiently when the inflow was 100 L/h, the sludge retention time was 10 d, the internal bypass ratio was 30% and the reflux ratio was 30%.
