Low-energy Water Supply

Lack of fresh water supply is a general and growing concern around the world in combination with the need to reduce energy consumption and developing new energy effective methods for producing fresh water. 

The term “low-energy water supply” covers a number of  technologies and methods and is subject to much research and development.

Desalination of sea and brackish water is one method and a common process is reverse osmosis (RO). Desalination and distillation via thermal vaporization process or by using waste heat from power production is also a possible technology. Another method is the production of electricity via renewable energy for pumping ground water from wells in rural areas or developing countries. Solar powered water pumps can work in conjunction with a controller for the pump - ensuring optimal water production from the break of day. 

Denmark has a long and strong tradition for research, development, production and export of various types of pumps suitable for covering various low-energy water supply applications around the world.
