Water Environment Research Open Access Article Examines Conditions Impacting Fine Pore Oxygen Transfer

The open access article in the May 2018 issue of Water Environment Research (WER) reviews factors affecting oxygen transfer in activated sludge processes.

“In their critical review of factors affecting fine pore oxygen transfer modeling, Baquero-Rodrıguez et al. delineate the major model inputs and variables and how they are affected by operating conditions (e.g., solids retention time, MLSS concentration, temperature, pressure, depth, diffuser type, etc.),” WER Editor-in-Chief Tim Ellis said. “The authors identify the need for additional model refinements that would provide an estimate of dynamic performance of oxygen transfer systems by including diffuser fouling as well as wastewater characteristics and operational conditions

Selected WER articles such as this one are available free to the public on a monthly basis through an open access program. In addition, authors can pay a fee to make their accepted articles open access.
