Japanese Engineers Tap Wastewater to Produce Clean Energy
A water treatment facility in Japan is exploring a novel form of renewable energy by tapping into the natural process of osmosis. This process, where water moves from a less concentrated solution to a more concentrated one, has long been understood. However, turning it into a reliable energy source has been challenging, mainly due to difficulties in developing effective membranes for the process. Over in the Fukuoka prefecture, engineers in collaboration with private partners believe they have made significant progress. They recently launched the second osmotic power plant in the world. The system generates electricity by using the interaction between treated wastewater and highly concentrated seawater, which is a byproduct of desalination. Osmosis is a familiar concept in everyday…
