Context: Bangalore Water Supply and Sewerage Board (BWSSB) is considering implementing Zero Bacteria technology in apartment Sewage Treatment Plants (STPs) to improve water quality.
About Zero Bacteria Technology:
- What is Zero Bacteria Technology?
-
- A water purification technology that eliminates bacterial contamination from water sources.
- Uses nanoparticle coatings, ultraviolet (UV) irradiation, electrostatic filtration, and specialized filtration systems.
- Developed by: Indian Institute of Science (IISc), Bengaluru.
- How It Works?
-
- Nanoparticle Coatings: Silver nanoparticles disrupt bacterial cell membranes, causing cell death.
- UV Light Irradiation: Destroys bacterial DNA, preventing replication.
- Electrostatic Filtration: High-voltage filters attract and trap bacteria.
- Specialized Filtration Systems: Removes bacteria using fine-pore filters, sometimes infused with antimicrobial agents.
- Key Features:
-
- Advanced bacterial elimination for high-quality treated water.
- Energy-efficient and sustainable solution for wastewater treatment.
- Reduces environmental contamination and enhances water reuse.
- Non-toxic and safe when used in controlled applications.
