WaterApp: Add-on Water Purification to Power Plants

Making pure drinking water accessible at low cost!

Business Concept

  • Supplying equipment to make pure water for power plants using the heat dissipated in their cooling loop.


More than half of the fuel used for electricity production ends up as waste heat instead of the desired product. The waste heat generally has a relatively low temperature (60-110⁰C). A WaterApp system can be connected to for example a genset through heat exchanger to recover the waste heat. The recovered waste heat from the genset will be enough to purify salty or other impure water to produce a clean drinking water.


WaterApp is dedicated to supply drinking water  based on low-temperature water purification technology. 
When the generation of electricity becomes more decentralized, small size power plants will become abundant. Recovery of  these scattered lower temperature waste heat can be achieved by plugging in water purification system. WaterApp provides a double-blade benefit by recovering the waste heat from power plants and supplying pure water for drinking and other applications. 


WaterApp delivers the following measurable functional benefits:

  • recovery of low temperature waste heat
  • supplying high quality purified water
  • provision of domestic warm water
  •  increased power plant efficiency


HVR WaterApp AB has been established to manufacture and sell a new plugin water purification device to power plants

HVR WaterApp AB is a spin-off from HVR Water Purification AB which licensed the technology to commercialize under the product 'WaterApp'.

MISSION: To mitigate global need for pure water.
