Oxygen transfer efficiency in an aerobic granular sludge reactor: Dynamics and influencing factors of alpha

In the pursuit of reducing carbon footprint and in view of increasing energy prices, energy efficiency is more important than ever before. Batch-wise operated aerobic granular sludge reactors consume up to 50% less energy compared to conventional activated sludge systems because pumping energy is reduced and mixing equipment is not needed....

Quick Scan model municipal concrete slab bridges: With additional research to the alpha reduction factor and shear force transmission in slab bridges

In this thesis, existing concrete municipal slab bridges are regarded. Many of these bridges were designed and built in the 1960s and 1970s. These bridges are still in service, and subjected to higher and more frequent loads than at the time of design. This leads to uncertainties in the safety of these bridges. Many municipalities become...
