Sustainable desalination with maximum energy efficiency

According to the UN, water scarcity is one of the major challenges facing the world today and tomorrow. The need to find sustainable solutions for new freshwater supplies is urgent; solutions that take the straight road from saline to fresh water at low cost and with minimum impact on climate and nature.

Due to its high energy efficiency and reliability, Sea Water Reverse Osmosis (SWRO) is one of the most sustainable and cost effective solutions for converting sea water to potable fresh water. At the same time, SWRO technology undergoes rapid development to improve energy efficiency and support large-scale freshwater production.

Features and benefits

Extremely low energy consumption

Ultra-low maintenance costs

Simple to operate

Minimal service and long service intervals

Small footprint but effective, compact and light in weight

Reverse Osmosis (SWRO)

Sea Water Reverse Osmosis may hold the key to prevent a global water crisis, but it requires powerful technology to be viable on a global scale.

Our four core technologies work together to make SWRO efficient and environmentally friendly.  

Danfoss takes lead in SWRO innovation

Danfoss is committed to supporting the sustainable desalination industry with energy efficient SWRO solutions. The product offering includes four core technologies, comprising high-pressure pumps, AC drives, energy recovery devices and pressure and fluid control devices. These combine into highly efficient and lasting water purification solutions that return energy savings of up to 65% compared to traditional centrifugal pump systems without energy recovery devices and drives.

By land, by sea - anywhere

At large scale, reverse osmosis plants are capable of providing freshwater to entire cities while compact solutions are ideal for supplying hotels and resorts, ships, and offshore facilities with clean water.

Today’s challenge – Tomorrow’s opportunity

Water is vital for life. Shortage of fresh water has spurred innovation to find efficient and climate-friendly solutions that turn seawater into fresh, clean water.

Reverse osmosis is the leading technology. It is simple, reliable and requires less energy than other desalination techniques.

    Canaragua uses Danfoss pumps and ERDs for ultra-compact RO plant in Gran Canaria

    Even though Canaragua has installed dozens of SWRO plants throughout the Canary Islands, the project in Puerto de Mogán was unusual because of the focus on compactness. The municipality needed to expand water production, and the best place to locate the new plant was in the middle of the historic town right off the main square.
