Unlock the opportunity to save water and energy

To treat water into a required quality involves varying degrees of water waste and energy consumption. That’s a significant challenge – but what if we could turn this challenge into an opportunity? It all starts with enhancing water efficiency and reducing energy use – and that’s where Grundfos steps in.

Demineralized water is essential for a wide range of industrial processes. With the industry's increasing focus on sustainability and resource efficiency, Grundfos has developed RO-PLUS. This advanced reverse osmosis plant achieves a water recovery rate of up to 90%, minimizing resource consumption without compromising operational reliability or water quality – it’s time to save water and energy.

Saving water across industries

From breweries to hospitals and district heating companies, our water and energy-saving solutions are making an impact across various industries, helping them decrease their consumption. 

Brewery

90.000 m³ saved annually

Since water is a key ingredient in the production of beer and soft drinks, Harboe Brewery places a strong emphasis on minimizing water wastage. 

By using water treatment plants optimised for high water recovery, Harboe Brewery saves up to 90,000 cubic metres of water per year. Every year! 

Hospital

Cutting water waste by 60%

Aarhus University Hospital, one of the largest hospitals in Denmark, has partnered with Grundfos to design and deliver a turnkey water treatment plant. 

The water treatment plant produces soft water and demineralized water used in the clinical biochemistry department, pathology department and joint sampling laboratories. The solution is equipped with water and energy-saving technologies that help reduce water waste by 60%. 

District heating

High water recovery and low operating costs

Aalborg Forsyning, a Danish district heating company, sought a water treatment solution with high water recovery and low Total Cost of Ownership (TCO) over a 15-year period.  

Grundfos designed a water treatment solution that minimizes operating costs by reducing water waste, electricity usage and regeneration salt consumption. 

Case stories: water for all of us

Boosting energy-efficiency with e-pumps

Treating and transporting water requires energy. That is why all reverse osmosis units from Grundfos are equipped with Grundfos E-pumps.  

They have the power to reduce energy consumption and costs and create more reliable plant operations. By using e-pump solutions instead of standard solutions, it’s possible to reduce energy consumption by as much as 37%. 

Transforming water waste into drinking water 

Efficient water resource management is a primary concern across various industries. While minimizing wastage in distribution networks is crucial, many water utility companies are now also focusing on reducing water waste in drinking water treatment. 

By treating and reusing backwash water from sand filters, it can be treated into drinking water once more. This innovative approach ensures optimal utilization of groundwater or surface water achieving a 100% utilization rate.
