The Barrel is a multi reverse-osmosis (RO) or nanofiltration (NF) pressure vessel that is designed to be a plug-and-play system. It ensures the fresh water produced meets all desalinated water quality standards for both municipal and industrial markets.  Its modular design makes it highly scalable, offering varying capacities from 400 to 50,000 cubic meters a day per unit.
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.
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.

Applications of  Barrel™ Pressure Vessel
