Aeration is the most energy-intensive operation in wastewater treatment, amounting to 45–
75% of plant energy costs. Fine-pore diffusers are today almost ubiquitous in municipal …

Gaseous compounds, such as CH4, H2, and O2, are commonly produced or consumed
during wastewater treatment. Traditionally, these gases need to be removed or delivered …

This paper outlines a multi-objective, integrated approach to analyze various possibilities for
increasing energy efficiency of the largest Italian wastewater treatment plant (WWTP) at …

Ambitious energy targets in the 2020 European climate and energy package have
encouraged many stakeholders to explore and implement measures improving the energy …

Aeration in wastewater treatment processes accounts for the largest fraction of plant energy
costs. Aeration systems function by shearing the surface (surface aerators) or releasing …

In this review, the factors affecting the transfer of oxygen in activated sludge processes using
fine‐pore diffusers for water resource recovery are critically discussed. In water resource …

Aeration is the most energy intensive unit operation in municipal wastewater treatment, and
fine‐pore diffusers have been widely used to minimize power consumption. Unfortunately …

Integrated fixed-film activated sludge (IFAS) processes are becoming more popular for both
secondary and sidestream treatment in wastewater facilities. These processes are a …

An OxyMem membrane aerated biofilm reactor (MABR) pilot of two~ 54 L reactors in series
with a hydraulic retention time (HRT) of 10 h each was successfully applied for the treatment …

Biological nutrient removal is practiced in various modifications of the activated sludge
process (ASP) throughout the world. This paper compares conventional, nitrifying-only and …
