Biomass is predominantly the major source of energy in the global south. It is the readily available source of energy in global south and is used in rural energy households in the form of wood, charcoal and agricultural residues. However, biomass energy source is not utilised in the most efficient way and hence there is still a gap in achieving...

Early fouling warning is important for the economical operation of membrane separation systems. In parallel multi-channel flow systems, flow re-distribution between channels due to fouling is often associated with maloperation. In the current research we use low magnetic field NMR to monitor multi-fiber hollow fiber membrane modules...

Catalytic ceramic nanofiltration (NF) is a promising technology for direct wastewater reclamation, given its high separation selectivity and reactive surfaces for oxidative removal of fouling. A better understanding of the relation between fouling types and oxidative cleaning efficacy under high organic loading conditions is of practical...

Under the rubric of project governance, governmentality has been defined as a general mode of governing people in projects, whether these projects are organized in an authoritarian, liberal, or neo-liberal mode in their approach to authority relations. We argue that governmentality is a specifically neo-liberal form of social integration, one...

In this study non-invasive low field magnetic resonance imaging (MRI) technology was used to monitor fouling induced changes in fiber-by-fiber hydrodynamics inside a multi-fiber hollow fiber membrane module containing 401 fibers. Using structural and velocity images the fouling evolution of these membrane modules were shown to exhibit...

Topology optimization is a valuable tool for the optimization of all kinds of structures. It can create highly efficient but complex designs. This complexity can make these structures challenging to clean. However, cleanability is often a requirement in, for example, the medical or food industries. Currently, no method exists to reduce the...

Aircraft turnaround optimization has recently gained attention from researchers, with the goal of freeing up capacity in congested airports. Most modern research focuses on the passenger boarding process. However, cabin cleaning also resides in the process critical path and an improvement of the cleaning lead time will therefore impact the...

Hospital waste has a major impact on the environment. The worldwide growth of hospital waste is the result of the growing world population and the increase in use of disposables. A circular healthcare economy may contribute to the reduction of hospital waste. The circular economy is a system in which waste is prevented and where waste is reused....

Bulk carriers load and unload large quantities of iron ore and coal at bulk terminals. The loading and unloading process on the EMO terminal is largely automated, but for the last 5% an excavator is used to remove material stuck on stairs and walls in the hold. This process takes many manhours, can be dangerous, and can cause damage. The...
