Nepal High-Precision Ozone Purified Water Project

Project Background 
The Nepal High-Precision Ozone Purified Water Project is an advanced water treatment initiative aimed at delivering safe, high-quality drinking water that complies with international standards to local communities. Leveraging state-of-the-art ozone purification technology, the project necessitates continuous real-time monitoring of critical water quality parameters to ensure optimal purification performance. Following a comprehensive evaluation process, Shanghai BOQU Instrument Co., Ltd. was selected to provide an integrated water quality monitoring solution due to its technical excellence and reliability.

Challenges and Requirements
- Simultaneous monitoring of pH, oxidation-reduction potential (ORP), and dissolved ozone concentration is required
- Equipment must demonstrate high measurement accuracy and long-term operational stability
- The system must operate reliably under Nepal’s diverse and fluctuating climatic conditions
- A low-maintenance, automated solution is essential for sustainable operation
- Full compliance with international water quality monitoring standards is mandatory

Selected Equipment
- MPG-6099EXT(Customized) Wall-Mounted Multi-Parameter Water Quality Analyzer
- BH-485 Digital pH Sensor
- BH-485 Digital ORP Sensor
- DOZ10.0 Digital Ozone Sensor
- pH/ORP/Ozone Flow Cell

Technical Advantages

- Integrated multi-parameter monitoring: A single analyzer enables concurrent measurement of three key water quality indicators, reducing system footprint and overall costs
- Advanced digital sensor technology: Ensures highly stable and precise measurements with superior resistance to electrical interference
- Automatic calibration capability: Minimizes manual intervention and supports unattended or remote operations
- Robust and durable design: Engineered to withstand extreme environmental conditions across Nepal, including high temperatures in lowland regions and sub-zero temperatures in mountainous areas
- Data integrity and traceability: Fully compliant with ISO standards, ensuring the credibility and reliability of monitoring data

Implementation Outcomes
- Enhanced measurement accuracy: Achieves ±0.01 pH for pH, ±0.01 mV for ORP, and ±0.01 mg/L for dissolved ozone concentration
- Reduced maintenance burden: Automatic calibration and self-diagnostic functions significantly decrease on-site service frequency and associated costs
- Improved data reliability: Digital signal transmission eliminates analog noise interference, preserving data integrity
- Simplified operation: User-friendly interface and remote monitoring functionality streamline system management
- Proven long-term stability: Continuous reliable performance under varying environmental conditions in Nepal
