Water Environment Research Open Access Article Examines Effect of Solids Retention Time on Particle Size Distribution, Reactor Performance

Jan. 8, 2018

The open access article in the January 2018 issue of Water Environment Research (WER) assesses the impact of solids retention time on key indicators of wastewater quality, including particle size distribution.

“In their paper on solids retention time (SRT) and particle size distribution, Li and Stenstrom used laboratory-scale modified Ludzach-Ettinger and integrated fixed film activated sludge systems to make key performance comparisons,” WER Editor-in-Chief Tim Ellis said. “They also studied five full-scale systems to observe the effect that SRT has on particle size distribution and sludge settleability. The study demonstrated that increased SRT led to larger mean particle size distributions and improved sludge settleability.”
