Forward Osmosis as a Pre-treatment to Reverse Osmosis

This paper presents some aspects of forward osmosis coupled with reverse osmosis using a recirculating draw solution, to produce desalinated water or for dewatering/concentrating a feed stream, with some data provided from a number of operational sites. Many of these aspects are applicable to other osmotic processes and provide an insight into where they may be appropriately considered. A compa...

Rotating reverse osmosis and spiral wound reverse osmosis filtration: A comparison

Wastewater produced by the crew members on a long-term space mission needs to be recovered as potable water. Reverse osmosis (RO) has long been in use as a physical membrane separation technology for wastewater treatment. However, membrane fouling and concentration polarization have limited the efficiency for high recovery reverse osmosis systems. An advanced high pressure rotating RO device wa...

Gravity-driven membrane filtration as pretreatment for seawater reverse osmosis: linking biofouling layer morphology with flux stabilization.

In this study gravity-driven membrane (GDM) ultrafiltration is investigated for the pretreatment of seawater before reverse osmosis (RO). The impacts of temperature (21 ± 1 and 29 ± 1 °C) and hydrostatic pressure (40 and 100 mbar) on dynamic flux development and biofouling layer structure were studied. The data suggested pore constriction fouling was predominant at the early stage of filtration...

Novel Membrane Materials for Reverse Osmosis Desalination

The use of solvents in desalination processes limits the use of certain materials in the construction of the reverse osmosis membranes. Therefore now the research effort has focused on improving new materials. In particular, nanostructured materials will probably form the basis for new reverse osmosis membrane materials. This study makes a review of the new materials used for the construction o...
