An optimal system design as well as advanced fault tolerant control is required to propose a cost-effective design and control of a seawater reverse osmosis (SWRO) desalination plant. Contrary to the steady-state model which is useful for only design, a dynamic model is essential to complete a plant

As water resources become more limited and waste discharge becomes increasingly problematic, the concept of water reuse is becoming important. Recently, use of greywater and rainwater as alternative water resources has drawn attention. However, lack of useful information on the combined use of greyw

A theoretical model to predict the porosity and specific resistance of cake layer was developed for better understanding a coagulation-microfiltration system for drinking water production. The model was based on fractal theory and incorporated intra-floc and inter-floc porosities as well as cake col

Rotating reverse osmosis (RO), which is based on Taylor-Couette flow, offers a means to minimize flux decline due to concentration polarization and membrane fouling. However, the operating conditions play a significant role in determining the effectiveness of the system. In this study, the effect of

Reverse osmosis (RO) is an efficient process for the removal of ionic and organic pollutants from contaminated water. In this study, rotating RO, which takes advantage of Taylor-Couette flow instabilities to reduce the flux decline related to concentration polarization and membrane fouling, was inve
