Possibilities for energy optimisation in design and operation of SWRO plants

Seawater desalination with reverse osmosis (SWRO) has taken a noteworthy upturn during recent years. One of the reasons for the success of the membrane process is its lower energy consumption in comparison with thermal desalination processes. The high-pressure RO desalination stage is undoubtedly the dominating energy consumer of an SWRO plant. Energy consumption of SWRO, despite its energy-recovery aspects, is also influenced by a huge number of additional factors. These are both of an external nature (eg, environmental conditions and stipulations), but are also determined by design and configuration of the plant. On the basis of an SWRO plant model, which covers the different pre-treatment and RO configurations and also the design with energy consumption of potabilisation and additional wastewater treatment and sludge dewatering facilities, the specific energy consumption of an SWRO and its subsystems has been determined in this article. Considering the various aspects to be taken into account for optimization of energy consumption in seawater reverse osmosis plants and the fact that in most cases these measures are offset by increases in capital costs for equipment or possibly also in chemical consumption, optimisation of the energy consumption of SWRO plants during planning and operation is a quite extensive and complicated matter and a demanding engineering task. This article is an expanded and updated version of the article published in the August/September issue of D&WR magazine.

The reverse osmosis pilot plant at Ras Abu Jarjur

Experience helps boost production and stability at Ras Abu Jarjur

Improving production with reduced expenditure could be the main targets of any desalination facility around the world. Such feats are being methodically achieved at Ras Abu Jarjur reverse-osmosis (RO) plant in Bahrain as a result of a series of improvements. Of the many available desalination techniques, RO was seen from the earliest days as a reliable and cost-effective technology and was therefore employed at Ras Abu Jarjur. From the huge quantity of groundwater (40 million m /year) extracted from borewells, potable water totalling 29 million m /year is produced. The other 30% of water is being rejected to the Arabian Gulf, which has a similar salinity level and higher temperatures. Trials are being carried out to extend the brine staging by one more stage from two to three for the ninth and tenth trains and from three to four for the first to eighth trains, as the reject water from the trains is already filtered, acidified, dosed with antiscalant and most importantly possessing the required pressure energy (minimum of 38 bar) to be used. This strategy would increase the overall water recovery by another 4.5%. By closely following the guidelines of the scaling indices, solubility product limits of potential scale-forming constituents in the water and various performance-monitoring tools, it would be possible to recover another 2% of the water. The full article first appeared in the November/December 2008 issue of D&WR magazine. The paper on which it was based was awarded the prize for Best Oral Presentation at the International Desalination Association World Congress in Maspalomas in 2007.

Depth Exposed Membrane for Water Extraction (DEMWAX™)

DXV Water Technologies has designed a novel membrane system that uses natural pressure, a very low recovery rate and gravity flow of feedwater past the membrane surface, resulting in an elegant, efficient system. Since the invention of the reverse-osmosis (RO) membrane researchers have tried to harness natural water-pressure, but past attempts mimic onshore processes with their configuration, recovery and flux. This low-flux low-recovery process will require more membrane than traditional systems; however, the elimination of intakes, outfalls, pre-treatment, pressure vessels and piping, energy recovery devices and coastal land will result in a water cost that is below many traditional sources. In addition to substantial energy savings, environmental and economic benefits that the DEMWAX system offers include: Mitigation of 'Brine' Disposal - the extremely low-recovery operation results in 'brine' at approximately 2-3% more concentrated than the surrounding ocean. Mitigation of Impingement and Entrainment - the intake velocity is several orders of magnitude less than typical intakes, virtually eliminating impingement and entrainment. Scalability - the system can be readily expan ded with the addition of cartridges and pumps. This article was published in the May/June 2009 issue of Desalination & Water Reuse.

Combining Forward Osmosis with Reverse Osmosis

A combination of forward osmosis with reverse osmosis could facilitate the treatment of some high fouling wastewaters. The system uses brine to draw water from the wastewater without high pressure or turbulence. Key element is the membrane's ability to allow rapid passage of water without much internal concentration polarization. The diluted draw solution can then be desalinated by reverse osmosis. The Two-Way Osmosis or TWO system may also be usable in very remote areas, where seawater ponds can be built for evaporative recovery of salt. Catalyx is designing a pilot system (patent pending) to desalinate seawater without external electric power. This article was published in the May/June 2009 issue of Desalination & Water Reuse.
