Design & Engineering Process
1. Research Phase
Explored technical feasibility and sustainability of various disinfection techniques, with emphasis on methods applicable in low-resource settings.
Comparing different water purification technologies
2. Brainstorming & Analysis
Used force field analysis to systematically evaluate the advantages and limitations of different purification technologies, considering factors like cost, durability, effectiveness, and cultural acceptance.
3. System Integration
After thorough analysis, we decided to combine three proven methods for maximum effectiveness:
Ceramic Filtration
Removes particles, bacteria, and protozoa through physical filtration
Solar UV Disinfection
Uses natural sunlight to inactivate microorganisms
Chlorination
Provides residual protection against recontamination
Integration of three purification methods in a single system
4. Material Selection
Selected materials based on sustainability, durability, and local availability:
- Ceramic Filters: Reusable and locally producible, reducing long-term costs
- PMMA (Polymethyl Methacrylate): Durable, UV-stable, and recyclable material for the main container
5. Prototype Modeling
Designed a stackable, transparent 20L cylindrical container with specific features:
- Dual ceramic filters to ensure sufficient flow rate
- Transparent body to enable solar UV disinfection
- Easy tap access for convenient water dispensing
- Compartment for optional chlorine tablets
