Jiwei Fork Level Switch and JWrada Radar Level Transmitter in Dubai Leachate Wastewater Treatment Project

Project Background

The Dubai Environmental Protection Agency launched a wastewater management upgrade project aimed at centralized treatment and automated monitoring of municipal solid waste leachate wastewater. Leachate is characterized by high organic load, suspended solids, corrosive and chemically complex composition, with storage tank operating temperatures typically ranging from 40–50°C. In addition, the treatment site involves heavy dust, steam, and potential foam interference, which places extremely high demands on level measurement instruments: devices must be highly reliable, corrosion-resistant, low-maintenance, and capable of maintaining stable performance over long operational cycles.

Key Technical Requirements of Dubai Leachate Treatment Project

Project Requirements in Dubai Leachate Wastewater Treatment

The project covered several critical storage tank systems, including:

  • Equalization Tanks: Regulating influent flow and balancing water quality to ensure stable downstream treatment;
  • Filtration Feed Tank: Storing leachate before filtration, requiring continuous monitoring to prevent overflow or dry pump operation;
  • Filtration Storage Tank: Holding filtered liquid to ensure continuous supply and smooth downstream processes;
  • Treated Water Storage Tank: Storing treated water for reuse or discharge.

High corrosion resistance and long service life

  • Probes are made of 316L stainless steel with anti-corrosion surface treatment.
  • Suitable for high-organic, high-suspended solids media, preventing corrosion and scaling.
  • Service life exceeding 5 years in harsh conditions.

High reliability and low maintenance

  • Vibration-based liquid detection eliminates mechanical sticking and false alarms.
  • Operates stably even under steam, foam, and dust interference, outperforming traditional float switches.

Flexible installation

  • Supports ANSI flange or NPT threaded interfaces, seamlessly integrating with existing tanks and reducing retrofit costs.

Safety certification

  • Ring-11 has achieved SIL2/SIL3 certification (IEC 61508 standard), meeting stringent industrial automation safety requirements.

Application of JWrada Radar Level Transmitter

JWrada-31 radar level transmitter

For large tanks and equalization basins, Jiwei supplied the JWrada-31 high-frequency radar level transmitter:

  • Non-contact measurement: Based on 80GHz millimeter-wave radar, unaffected by adhesion or corrosion.
  • Long range and high precision: Maximum range up to 150m, accuracy within ±1 mm, meeting long-distance measurement needs.
  • Advanced echo recognition: Proprietary algorithms enable stable operation even in low dielectric liquids, steam, or foam environments.
  • Smart operation: Built-in Bluetooth debugging and “Jiwei SmartControl” mobile app support remote monitoring and IIoT integration.

Level Monitoring Point Layout and Full-Coverage Solution

Design and Drawing Validation

  • Based on customer-provided AutoCAD drawings, Jiwei engineers designed the monitoring point layout to ensure full coverage.

On-site Installation and Commissioning

  • Ring-11 switches installed with quick wiring; JWrada radar calibrated via Bluetooth app, ensuring instant and accurate data.

System Optimization

  • Radar transmitters used for continuous level monitoring, while tuning fork switches provided high/low alarms, forming a complementary system.

Data Monitoring and Maintenance

  • Real-time level curve monitoring, automatic alarms, and maintenance reminders reduced field inspections significantly.

Project Results

After installation and commissioning, the Ring-11 tuning fork level switches and JWrada radar level transmitters have been running stably across various storage tanks in the Dubai leachate wastewater treatment project.

  • Reliable performance under high temperature, dust, steam, and foam interference.
  • Continuous and accurate measurement, reducing maintenance frequency by about 60% compared to float switches.
  • Complementary system: radar for continuous monitoring, tuning fork for high/low alarms.
  • Cost savings: approximately 35% lower than imported brands VEGA/E+H, with shorter delivery time.
  • Customer feedback confirmed stable operation, fast alarm response, and improved operational efficiency and environmental safety.
