Danfoss highlights energy-efficient zero liquid discharge (ZLD) and seawater reverse osmosis solutions at this year’s Membrane Technology Conference
The UN Environment Programme (UNEP) estimates that 1.8 billion people will likely face absolute water scarcity, and that two-thirds of the global population will experience water stress – not at some distant point the future, but in 2025. These estimates alone illustrate the importance of finding ways to recycle and reuse more water. Yet, seawater reverse osmosis (SWRO) and zero liquid discharge (ZLD) – two of the main processes for producing more fresh water – require significant amounts of energy, at a time when the world’s focus is on decarbonizing energy-intensive industrial processes. Thankfully, it is possible to create more water while using less energy, with solutions that are readily available today.
At the 2025 Membrane Technology Conference, Danfoss experts will showcase solutions that improve energy efficiency in desalination, zero liquid discharge and brine mining processes, including:
- High-pressure APP pumps optimized for land-based, off-shore and marine SWRO, as well as zero liquid discharge (ZLD) and minimum liquid discharge (MLD) applications. The Danfoss booth will also feature the award-winning ceramic APP pump, recipient of the Water Technology Idol at the 2024 Global Water Summit, and the Miriam Balaban Award at Euromed 2024.
- iSave® energy recovery devices for high-pressure membrane applications. The iSave features an innovative 3-in-1 design that integrates a pressure exchanger, booster pump and motor. It recovers 94% of the high-pressure energy that would otherwise be wasted during the process, resulting in up to 60% energy savings for plant operators.
Meeting the dual challenges of water scarcity and climate change requires that we develop energy-efficient membrane processes. The less energy we use, the lower their financial costs and carbon footprint, and the more widespread these water treatments will become. This will help us meet people’s need for fresh water, while meeting the planet’s need for fewer carbon emissions.
