Development of Coagulation-MF-Dedicated RO for RO Brine Recovery in Water Reuse

This paper discusses the development of a new integrated process composed of biological activated carbon/coagulation/microfiltration/dedicated RO. The objective was to recover 25% RO brine generated from the current water reuse facility and to enhance the overall water recovery from the current 75% up to 94% in a water reuse application. The paper describes experiments were carried out in lab scale and batch operation. It concluded that there was a potential to meet the objective but that the work needed further investigation.
