Portable Smart Water Purification System

University gradation project that I need to complete to build a prototype in the university laboratory using 3D printing and materials provided by the university.

## ? CHALLENGE SUMMARY
**Objective**: Build a **functional, portable Smart Water Purification System** that:
- Purifies 40 liters/day (for 20 people)
- Runs on limited solar power
- Monitors water quality
- Supports predictive maintenance
- Sends remote alerts/data
- Weighs < 15 kg
- Is scalable and user-friendly

## ✅ DELIVERABLES
1. **1-Page Development Plan** (due April 13, 4:00 PM)
2. **Working Prototype** (with smart features)
3. **Live Demo & Testing**
4. **Future Outlook Document**

## ? CONSULTANT-STYLE STRATEGIC PLAN

### PHASE 1: INITIAL STRATEGY & PLANNING (Days 1-2)

#### **Team Structure (for your plan)**
- **Project Lead**: Coordination, timelines, team communication
- **Mechanical Engineer**: Physical system, structure, flow mechanics
- **Electrical Engineer**: Power management, sensors, microcontroller
- **Software/Data Engineer**: Predictive maintenance, dashboard, remote alerts
- **UX Designer**: Portability, usability, component accessibility

#### **Key Milestones**
| Day | Milestone |
| 1 | Finalize system design, assign tasks, BOM (Bill of Materials) |
| 2 | Complete component sourcing + early software/hardware integration |
| 3-4 | Build purification system + integrate sensors and solar power |
| 5 | Smart features: alerts, dashboards, data logging |
| 6 | Test full system: water output, data, power draw |
| 7 | Polish demo, simulate failures, prepare pitch and future outlook |

#### **Development Plan Must Include**:
- Task breakdown per person
- Core features + stretch goals
- Materials and sensors list
- Timeline (use a Gantt chart or bullet format)

### PHASE 2: SYSTEM DESIGN CONSIDERATIONS

#### ? **Purification Stack** (Safe Drinking Water)
- **Sediment filter (5 micron)**
- **Activated carbon filter** (removes chlorine, VOCs, some metals)
- **UF or RO membrane** (for biologicals + dissolved solids)
- **UV or Chlorination** (final disinfection)
- **Oil separator** (oil skimmer pad or hydrophobic membrane)

Keep waste discharge < 25%. So if input is 53.3 L → output must be 40 L.

#### ? **Power System**
- Use **12V solar panel + Li-ion battery (7-20Ah)**
- Use **DC pumps** (low energy) and **MCU (ESP32 or similar)**
- Efficient scheduling: only run sensors when needed

---

### PHASE 3: SMART SYSTEM ARCHITECTURE

#### ? **Monitoring**
- **Sensors**: Turbidity, pH, TDS, flow rate, battery voltage
- **Microcontroller**: ESP32/Arduino + RTC + SD card or ESP32 with Wi-Fi
- **Predictive maintenance**: use linear regression or rule-based logic for early warnings

#### ? **Remote Communication**
- **LoRaWAN (low power, long range)** if no cellular
- **GSM (SIM800/900)** if GSM coverage exists
- Send data to a cloud service or custom dashboard
- Simulate this in the demo with a test server or local dashboard + alert emails

---

### PHASE 4: PROTOTYPING & DEMO STRATEGY

#### ?️ **Build**
- Use **modular tubing + clamps** for easy servicing
- Encase electronics separately, with waterproofing
- Document everything for easy replication

#### ? **Demo Checklist**
- Show **before/after water test** (turbidity, pH, TDS)
- Simulate filter nearing failure → trigger alert
- Send alert to mock server/email
- Show **power draw metrics** on solar setup
- Demonstrate dashboard or interface

---

### PHASE 5: FUTURE OUTLOOK

#### ? **Scalability Plan**
- Add more filters in parallel
- Use bigger solar panels
- Modular stack: "plug-in" more units for larger villages

#### ? **Innovation Highlights**
- AI-powered predictions
- Reusable filters, biodegradable casings
- Dashboard for regional water mapping
