Desalination Project
Advanced water purification solutions for coastal communities
Program Overview
Our desalination project addresses water quality challenges in coastal regions of Bangladesh where saltwater intrusion affects drinking water sources. Through innovative filtration technologies, we’re working to provide sustainable clean water solutions.
This initiative combines modern desalination techniques with community-based maintenance systems to ensure long-term water security in areas most affected by climate change and rising sea levels.
Region of Work
Location: To Be Determined
We are currently evaluating coastal regions for implementation
Capacitive Deionization
Electrosorption process using porous electrodes to remove residual ions under applied voltage
Methodology
1. System Design & Components
Designed by high school students using principles from electrical engineering and energy systems, the desalination system combines:
- Activated carbon pre‑filter – removes odor and large particles before further treatment.
- Reverse osmosis (RO) stage – a pump forces water through a semi‑permeable membrane to separate contaminants from the purified stream.
- Capacitive deionization (CDI) stage – removes residual ions via electrosorption; porous electrodes capture charged particles under an applied voltage.
2. Power Supply
A small solar panel, supplemented by backup batteries, will provide uninterrupted power for both the RO pump and CDI system.
3. Performance Estimates
The system is projected to achieve:
75%
