Leveraging nanotechnology for next generation seawater desalination
NanoH2O advanced membranes for reverse osmosis (RO) desalination represent a new material that enhances current polymer-based membranes with the benefits of nanotechnology. These nanocomposite RO membranes represent a step-change in productivity through improved permeability while maintaining requisite salt and contaminant rejection. Since the original publication of this concept, further development and optimization of this membrane technology for seawater reverse osmosis (SWRO) has resulted in an enhanced flux of more than double that of a 22.7 m /d (6,000 gpd) commercial baseline with 99.7% salt rejection. Recent seawater field testing of an industry-standard spiral-wound element module including the TFN material combined with a fabric support base topped with a microporous polysulfone layer has supported current laboratory research findings.

Solar pond and membrane distillation merger in Nevada University
Membrane distillation (MD) is a thermally driven membrane separation process that involves evaporation of volatile constituents (water in desalination applications) through a hydrophobic, microporous membrane. The vacuum-enhanced MD process recently patented by researchers at the University of Nevada, Reno in the United States has now been coupled with some equally interesting research at the university on solar ponds. The configuration is now being studied using a small-scale indoor pond and new capillary MD membranes. While MD has been studied in the past in conjunction with solar ponds, new membranes, new techniques and new auxiliary technologies are improving MD, solar ponds and their synergistic combination. This article was first published in the February/March 2010 issue of Desalination & Water Reuse magazine.

The coming of membrane distillation technology
Membrane distillation (MD) is a unit operation that uses hydrophobic membranes as a barrier for contaminated water from which mass transport of vapor is driven by differences in vapor pressure. MD does not require a mechanical pressure pump, and temperature levels are such that low-grade heat sources may be used to supply the required energy for the process. It is therefore ideal for treatment of industrial effluents and for desalination in co-generation with thermal solar power plants. This article assesses membrane distillation, a technology that the author believes is becoming increasingly relevant, particularly for use with renewable energies and in less developed countries. The recent promotion of the Desertec energy creation project in the Sahara is just one opportunity he sees for the technology.
Solar membrane distillation ideal for remote areas
Fraunhofer ISE develops solar thermally driven compact desalination systems based on membrane distillation for a capacity range between 100 and 500 L/d and larger system capacities up to 10 m³/d. A modular design of systems is important in order to resize them to a wide range of user profiles. Membrane distillation (MD) is a separation technique which combines a thermally driven distillation process with a membrane separation process. The thermal energy is used for phase changing of liquid water into vapor. Unlike membranes for reverse osmosis (RO), which have a pore diameter in the range of 0.1 to 3.5 nm, membranes for MD generally have a pore diameter of 0.1- 0.4 m. The separation effect of these polymer membranes is based on their hydrophobic nature. Apart from some experimental systems, the MD-technique has not been used for desalination up to now, but, for implementation of solar-driven stand-alone desalination systems, it holds important advantages. The article describes two developed types of solar-driven MD system and discusses their installation and economic performance. The full article first appeared in the November/December 2008 issue of D&WR magazine
