TL;DR: In this article, a model that considers changes only to solute and solvent properties was proposed to evaluate separation performance and humic acid fouling for two RO membranes treating brackish water at temperatures of 15, 25, and 35°C.

TL;DR: In this paper, an automatic flushing and cleaning system for membrane separation machines such as reverse osmosis machines having plural modules or membranes is described, along with a complete timer operated electrical sequencing system whereby desired purging, flushing, and cleaning cycles are automatically undertaken at periodic intervals or in response to one or more preferred conditions.
Abstract: An automatic flushing and cleaning system for membrane separation machines such as reverse osmosis machines having plural modules or membranes. Cleaning may be by way of reducing the pressure to allow the membrane to relax, by the injection of air or inert gas to provide turbulence, and/or by injection of flushing liquid which may include chemical cleaning additives. Pumps, automatic valving, and pressure controls are provided, along with a complete timer operated electrical sequencing system whereby desired purging, flushing and cleaning cycles are automatically undertaken at periodic intervals or in response to one or more preferred conditions.

TL;DR: In this paper, an irreversible thermodynamic model coupled with film theory was applied to quantitatively analyze the experimental observations and the model accurately predicted the boron rejection performances of the SWRO membranes at different operating conditions.

Journal ArticleDOI
TL;DR: In this paper, a real-time, non-invasive, in situ measurement of membrane fouling using ultrasonic time-domain reflectometry (TDR) is presented. But, the results show a good correspondence between the decline in the ultrasonic signal amplitude and the development of a fouling layer and suggest that ultrasonic TDR may be particularly responsive to fouling initiation and its subsequent removal during membrane cleaning.
