Compact and simple design
Due to its high energy-efficiency and reliability, SWRO has turned into one of the most sustainable and cost effective desalination solutions for land-based, offshore and marine applications. The technology is reliable and safe with high-pressure pumps forcing seawater through desalination membranes to create fresh water. Danfoss supplies expertise and unique technologies that can offer your business high efficiency, low maintenance and flexible configuration.
With efficiency rates up to 92%, the APP pump technology offers the highest efficiency in the industry.
The simple construction of the pump offers reliable operation with long service intervals and easy maintenance.
The small and compact size of the pump allow flexible configuration in almost any environment.
Danfoss iSave is a patented, high-efficiency Energy Recovery Device (ERD) that guarantees constant membrane feed in SWRO applications of any size – on land, at sea or on the move.

As global demand for lithium, magnesium, and food-grade salt surges, brine mining is emerging as a less environmentally disruptive alternative to conventional mining. But brine valorization is only economically viable if energy use and system complexity are kept in check.
Danfoss APP pumps and iSave ERDs form the foundation of ultra-energy-efficient SWRO and OARO systems. They deliver the precise, stable high-pressure performance needed to make brine valorization commercially and environmentally feasible.
The global water challenges call for innovative solutions. Desalination is fast becoming a leading technology to transform sea water into clean fresh water for multiple purposes.
