The region has experienced a years-long drought
On Kili, a remote, drought-stricken atoll in the Marshall Islands, the region's second permanent solar- and wind-powered water desalination plant is now operational. Earlier this year, a similar plant was installed on Utrik, 400 miles to the north.
Numbers show positive trends in conservation
Water use across the country has reached its lowest recorded level in nearly 45 years. According to a new USGS report, about 355 billion gal per day (gpd) were withdrawn for use in the entire U.S. during 2010.
This represents a 13% reduction in water use from 2005, when about 410 billion gpd were withdrawn, and the lowest level since before 1970.
With the global population estimated to grow from 7 billion in 2011 to more than 9.5 billion by 2050, profound stress has been placed on the world’s limited water supply, not only by its burgeoning population, but also by other factors, such as rapid urbanization, industrialization, pollution and climate change.1 As water scarcity and “water stress” persist, the water treatment industry has been tasked with developing innovative solutions to produce clean, potable water.
Demand for Desalination
Popular vacation spot uses RO desalination to produce drinking water
Filmtec Seamaxx RO elements offer low energy consumption and an optimized module design that helps maximize the productivity of a desalination system with low differential pressure, low cleaning frequency and high cleaning efficiency. Producing up to 99.7% water purity, up to 10% energy savings and less fouling at high operating flux, they are ideal for applications that treat medium to high TDS, brine and high-salinity brackish water.
The island of Anguilla in the British West Indies is one of the northernmost Leeward Islands in the Atlantic Ocean. Like many Caribbean islands, tourism is its main industry, with more than 100,000 visitors each year.

When people find out I am involved with the water treatment industry, there is one topic that almost always comes up: the ongoing drought in California and other states, and what is being done about it.
In February, government officials from the Republic of Maldives joined representatives from the Aquiva Foundation, memsys, Aquaver and the local power company, Stelco, for the official commissioning of a desalination facility on the island of Gulhi that will bring a sustainable and reliable supply of drinking water to its residents.

Companies will pursue seawater desalination for remote islands and communities in Indonesia
memsys Clearwater Pte. Ltd. and PT. Dwiputra Sumber Sukses (DSS) have entered into a license agreement to pursue seawater desalination for remote islands and communities and brine concentration for targeted industrial applications in Indonesia utilizing memsys’ membrane distillation (MD) technology. The first unit, with a capacity of 100 cu meters per day, will be built in 2014.
Operating data from memsys technology shows positive desalination with net energy production
Operating data from an installation of seawater desalination units that employ memsys’ membrane distillation technology indicates a significant net gain in energy production from the diesel generators that power the system. memsys, a Singaporean-German company, pioneered the technology, which is based on vacuum multi-effect membrane distillation (V-MEMD), a highly efficient thermal process for thermal separations in a modular concept.
Tiny Utrik Atoll is part of the Marshall Islands, a scattered group of atolls in the northwestern Pacific Ocean. On Utrik and neighboring islands, rain catchment traditionally supplied all of the drinking water, while well water was used for washing. Over the past decade, however, rainfall has become unreliable, and during the dry seasons Utrik islanders were forced to drink well water with unsafe salinity levels.
