Abstract: Computational fluid dynamics (CFD) has been applied in secondary settling tank (SST) analysis for more than 30 years. Although great progresses has been achieved, there are still some uncertainties in CFD SST modeling. ...

Abstract: Recent developments in wastewater aeration systems have focused on aeration efficiency and minimum energy cost. Many other operating characteristics are ignored. The impact of aeration system alternatives on aeration‐basin ...

Abstract: A dynamic model was developed to predict activated-sludge aeration basin temperature. The model accounts for hourly or more frequent changes in weather conditions and input parameters such as wastewater temperature, aeration, ...

Abstract: Off gas analyses of oxygen transfer efficiency (OTE) at Terminal Island Treatment Plant of Los Angeles document changing performance of fine-pore diffusers in an activated sludge plant from 1991 to 1998. Although the plant ...
