IIT Guwahati Develops Low-Cost Water Treatment for Fluoride, Iron
Scientists at IIT Guwahati created a new machine to clean up water.
This machine takes out bad stuff like fluoride and iron that can be in water from the ground.
Too much fluoride can hurt your bones.
The new machine can clean a lot of water, about enough for a small town each day.
It removes most of the iron and fluoride and makes the water safe.
The best part is that it is cheap to use.
They are using this machine in places like Assam, where it can help people get clean water.
IIT Guwahati developed a low-cost water treatment system.
The system removes fluoride and iron from groundwater.
It can treat up to 20,000 liters daily, ideal for rural areas.
The system effectively removes iron (94%) and fluoride (89%).
Treatment cost is approximately Rs 20 per 1,000 liters.
