Welcome to the Danfoss High Pressure Pump Blog

Do you know the carbon footprint of the fresh water in your glass?

Our first blog takes a close look at the interdependence of water and energy – the so-called “water-energy nexus”– to understand the energy intensity of the five main types of treated water: surface, groundwater, brackish groundwater, recycled water, and desalinated seawater.

People have turned to available technology to make seawater drinkable for thousands of years. The energy needed to do this, however, has always played a role in how widespread desalination could become.

In this blog, we look at the energy intensity of desalination throughout history. From thermal distillation to SWRO, the energy intensity of desalination has dropped dramatically over the last 100 years – and will most likely continue to fall in the future.

Desalination is the most energy-intensive source of potable water, requiring much more electricity to produce than ground or surface water. But all desal technologies were not created equal.

This blog examines the potential savings if all existing desal plants were retrofitted to be as energy-efficient as current technology allows. Whether you look at electricity usage and cost or CO₂ emissions, the opportunity to save is huge.
