Research Papers by W. Richard Bowen

At its best, engineering changes the world for the benefit of humanity. However, there are at present significant imbalances in engineering development. In some instances, appropriate technology is available but is not being applied, such as in water treatment. In other instances, inappropriate tech

The conjectured development of early biological membranes is outlined and their properties reviewed. It is suggested the mimicking such early structures could lead to the development of new types of highly selective membranes.

An important challenge for nanofiltration processes is the development of predictive models that convey a fundamental understanding and simple quantification of the governing phenomena in a way that has the potential for industrial application. The paper reviews one such approach, including: the for

AFM has been proved to be a rapid method of assessing membrane–solute interactions (fouling) of membranes under process conditions. The interactions of developmental membranes (SPEEK/PSU and PSU) with different solutes have been directly measured and linked to process performance. Correlation of the

Sulfonated poly(ether ether ketone) (SPEEK), a strong polyelectrolyte, was investigated as an additive in polysulfone (PSU)/SPEEK/N-methyl-2-pyrrolidinone (NMP) systems. Membrane characterisation was carried out using filtration studies and by atomic force microscopy (AFM). The effect of SPEEK in th
