The only way to achieve a sustainable freshwater supply in the long-run is by making wastewater reuse affordable — a complex process that requires increasing amounts of energy. At the same time, energy generation, storage and transformation also requires increasing amounts of water. This mega trend, known as the Water- Energy Nexus, poses one of the main challenges of the 21st century. Both industrial and municipal markets require innovative technological solutions for water treatment which are both efficient and sustainable. At akvola Technologies we believe that making wastewater reuse an affordable and sustainable water source is essential to the future development of mankind in terms of economy, environment and society.
