A safe, compact and digital RO desalination system. Its plug-and-play approach helps to secure a fast-track schedule while its embedded digital sensors provide remote monitoring.
The Barrel was introduced to the market by SIDEM — a Veolia Water Technologies subsidiary — in 2019 as a major innovation for seawater desalination; however, it soon became obvious that the technology also perfectly addressed the challenges associated with water reuse.
How the Barrel works
The Barrel enables the RO process implementation to be strictly identical to that of current RO pressure vessels. This ensures the fresh water produced meets all desalinated water quality standards for both municipal and industrial markets. It is also suitable for wastewater reuse and low pressure RO applications.
Its carbon steel pressure vessel is manufactured and tested off-site, and is delivered as a single unit so installation on-site can be fast-tracked and project schedules shortened.
In addition, its modular design makes it highly scalable, offering varying capacities from 400 to 50,000 cubic meters a day per unit. It can also be used in place of existing RO membranes and nanofiltration skids for a more economically viable, sustainable and innovative alternative.
Compact and suitable for outdoor installations, the Barrel offers a footprint reduction of up to 25 percent and does not require a controlled environment. The sustainable solution also provides a reduction in electrical consumption in the range of 0.05 kilowatt-hour per cubic meter of fresh water produced.
Meeting the demand for clean water has never been more challenging but the Barrel helps our customers secure their supplies by creating an economically viable and sustainable source of freshwater.
Reliable production of the same quality as fresh water but at a lower cost.
Economically viable and sustainable source of fresh water.
Easy to operate, it allows remote diagnostics and predictive maintenance thanks to its embedded digital devices.
Reuse of treated wastewater creates a new water cycle in a planned and supervised way.
The Barrel is more than a means to take salt from seawater. It is a reverse osmosis or nanofiltration technology that has the power to solve many of our water resource issues, from securing residential drinking supplies to helping to ensure business resilience as the demand for water sharply rises. And after treatment, wastewater (municipal or industrial) becomes too valuable to dispose of and so we use the same technology to facilitate its reuse.

FAQ about Barrel™
What is desalination?
Desalination uses reverse osmosis membranes to separate salt and other molecules from seawater. Seawater is pushed through hundreds of tightly-wrapped, semipermeable membranes under very high-pressure. The membranes allow water to pass through, leaving salt and other molecules and impurities behind.
Why is desalination so important?
By 2040, it is estimated one in four children worldwide will be living in areas of extremely high water stress; however, water scarcity already has far-reaching consequences today. From Qatar and Saudi Arabia to Spain and Australia, large parts of the world are already feeling the impacts of climate change on their water resources. Desalination is an effective way of tackling water scarcity issues in arid coastal areas and secondly by facilitating water reuse.
How can water reuse combat water scarcity?
By removing dissolved solids and unwanted minerals from wastewater the same reverse osmosis-based technology means the water can be recycled several times, reducing the environmental impact of extracting fresh water. Water reuse has such a huge potential in addressing global water scarcity, it is cited as an official means of achieving Sustainable Development Goal six which focuses on ensuring the availability and sustainable management of water and sanitation for all. As a result, reuse is becoming a legal requirement in many countries.
Reusing treated wastewater for indirect drinking water production— a first for Europe. The Barrel with a capacity of 3,600 cubic meters per day, has been delivered to the site. The full project is now under construction, testing will start in 2023 with full production scheduled for 2026.
