“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
