Scientists built a new computer system that watches water cleaning in real time. The system uses AI to check if water treatment is working well. It also helps factories save energy and recycle useful materials. Water cleaning is not only about removing bad stuff anymore. Now it must also fight climate change and help the economy work in circles.
Ammonia-nitrogen is very important in water. Too much of it hurts fish and other water animals. But if people handle it carefully, they can get useful things from it. The study shows that water plants need to be both green and smart. They must use new technology and think about the whole system together.
