Bengaluru to Build DNF Water Recycling Plant
Imagine a giant water cleaner being built in Bengaluru!
This special plant uses a new method called direct nanofiltration (DNF) to clean used water from sewage treatment plants.
The cleaned water can then be used again in buildings for things like cooling systems, instead of using fresh water.
The technology is very efficient, removing tiny bad stuff like metals and chemicals.
A company called Ceramed Engineers is building this plant with help from the local water company.
It's like giving the city a way to reuse water and save the planet!
Ceramed Engineers will build a direct nanofiltration (DNF) water recycling plant in Bengaluru, partnering with the Bangalore Water Supply and Sewerage Board (BWSSB).
The plant will treat sewage water and upgrade it for reuse in HVAC systems and construction.
The project uses NX Filtration's DNF technology, which removes heavy metals, pesticides, and other contaminants.
The technology aims to make cities future-ready by reusing every water drop efficiently.
The DNF technology has lower operational costs than conventional systems.
