Maltese desalination test-bed shows SalTec energy-recovery advantages

Throughout the desalination industry, plant operators are looking for long-term solutions with lower lifecycle cost because of the link between water costs and energy costs. In order to meet operators' demands and requirements, equipment manufacturers are investing considerable resources in the development of new technologies that will reduce energy costs. The Water Services Corporation in Malta is one example of a forward-looking operator of a seawater reverse-osmosis (SWRO) plant seeking to ensure the production of high-quality drinking water at an affordable price. Established in 1993 to produce and distribute potable water on the islands of Malta and Gozo, WSC has an annual production target of 35 million m to satisfy the needs of its 400,000 residents and in excess of one million tourists. With the drive to produce greater efficiencies and water quality WSC has taken an opportunity to investigate and monitor the potential of a new technology from KSB, the SalTec pressure boosting and energy recovery system. The SalTec DT pressure exchanger in combination with KSB's HGM RO high-pressure pump creates a highly attractive proposition for RO plant designers and operators. The SalTec DT system provides a nominal capacity of 250 m /h, giving it the capability to operate in plants with train sizes ranging between 4,400 m /d and 5,000 m /d of permeate at common recovery rates.

Doing away with RO energy-recovery devices

Energy-recovery devices have been a crucial element in the reduction of the cost of desalination during the past decade, bringing the technology within reach of conventional water resources costs in certain circumstances. Typical energy consumption for seawater reverse osmosis (SWRO) is now around 2.5 kWh/m . Desalitech's Closed Circuit Desalination, which does away with an energy-recovery device, reports energy consumption for SWRO of 1.65-1.87 kWh/m . This article was first published in the August/September 2010 issue of Desalination & Water Reuse magazine.

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.

Korea puts $170m into desalination SWRO and water reuse

The Republic of Korea has recently funded a six-year US$ 170 million research initiative in seawater desalination. Over 500 researchers from 16 universities will contribute to the work of the 50-member core team. Government leaders funded the research initiative in part due to the success of South Korean multinational firms in the desalination export sector. However, the South Korean desalination initiative has a humanitarian goal as well, since much of the world's population faces a future of uncertain access to clean water. SeaHERO (Seawater Engineering & Architecture of High Efficiency RO) was launched by the South Korean government in August 2007. The program is coordinated by In S Kim, executive director of the Center for Seawater Desalination Plant located at Gung Ju Institute of Science & Technology. The six-year program has the goal of providing innovation in reverse-osmosis membranes, energy recovery and reducing the cost of engineering, procurement, construction, operation and maintenance.

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.
