GWQ-MP200 Multi-parameter Water Quality Analyzer
Optimizing Wastewater Treatment & Effluent Compliance

From influent to discharge — real-time pH, COD, ammonia nitrogen, dissolved oxygen, turbidity monitoring for stable operation & environmental compliance
📍 Project Location: Industrial Park WWTP / Municipal WWTP Upgrade Project
💧 Application Scenarios: Influent early warning, DO control in bioreactors, secondary sedimentation turbidity, effluent COD/ammonia monitoring
📅 Implementation: 2024 – present  |  Equipment: GAIMC GWQ-MP200 Multi-parameter Water Quality Analyzer (multi-channel combination, supports pH/COD/Ammonia/DO/Turbidity/Residual Chlorine)
🏭 Wastewater Treatment Challenges & GWQ-MP200 Core Value
Municipal and industrial wastewater treatment plants face significant challenges: fluctuating influent quality, precise oxygen control requirements in biological processes, and increasing pressure to meet discharge permits. Traditional lab sampling is slow and fails to respond to shock loads in time. The GWQ-MP200 multi-parameter analyzer features a high-reliability real-time operating system (RTOS) and connects digital sensors for pH, COD, ammonia nitrogen, dissolved oxygen, turbidity, residual chlorine, etc. It enables 24/7 continuous online monitoring of influent, biological tanks, secondary clarifiers, and effluent. Data is transmitted via RS485 (Modbus-RTU) and 4-20mA to PLC/DCS systems for alarm and automatic process control, significantly improving system stability and shock-load resilience.

🌫️ Turbidity / Suspended Solids Monitor sedimentation efficiency, aid sludge settling judgment Built-in 8GB TF card (expandable to 32GB) for local backup
🌱 COD / Ammonia Nitrogen Influent load assessment, key effluent compliance indicators Multi-channel relay control, supports alarm & return flow

🎛️ Flexible Multi-parameter Combo

Tailor parameter combinations for each treatment stage (COD+Ammonia+DO+pH+Turbidity) with one instrument covering critical process points.

📲 Smart Communication & Integration

2x RS485 Modbus-RTU, directly connect to SCADA for remote alarms, trend analysis, and process adjustments.

💾 Massive Historical Storage

Standard 8GB TF card (up to 32GB) stores years of water quality data for environmental audits and process optimization.
📈 Proven Results: Effluent Compliance +23%, Aeration Energy -18%
At an industrial park WWTP (20,000 tons/day), two GWQ-MP200 units (total 8 channels) were deployed at the influent, aerobic tank, secondary clarifier, and final discharge point. By continuously monitoring COD, ammonia, DO, pH and linking with blowers and return pumps, after 6 months: effluent COD stably below 40mg/L, ammonia below 2mg/L, compliance rate increased from 87% to 98.5%; DO fluctuation in aerobic tanks reduced by 52%; aeration blower energy consumption decreased by 18%; and early ammonia warning prevented three biological system shocks. Manual lab testing workload reduced by 70%.
🔧 Technical Highlights (Based on GWQ-MP200 Product Manual)
✅ High-reliability real-time OS, touch configuration & automatic temperature compensation for harsh WWTP environments.
✅ Multi-channel isolated 4-20mA outputs (load < 750Ω) + two RS485 Modbus-RTU ports for seamless PLC integration.
✅ Relay control for chemical dosing pumps, VFDs, or alarms. Wide power supply 100-250VAC.
✅ Wall-mount main unit (223*200*120mm) + immersion/threaded electrodes, IP-rated for wet environments.
✅ Expandable parameters: pH, ORP, conductivity, DO, residual chlorine, ozone, turbidity, COD, BOD, ammonia, chlorophyll, cyanobacteria, etc., meeting upgrade requirements.
📦 Recommended Configurations for WWTPs
Based on wastewater process characteristics, GWQ-MP200 recommended configurations:
  • Influent Early Warning: COD + Ammonia + pH + Conductivity (4 channels) for real-time shock load monitoring;
  • Bioreactor Control: Dissolved Oxygen (DO) + pH + Temperature (3 channels) for aeration & return flow;
  • Effluent Compliance: COD + Ammonia + Turbidity + Residual Chlorine (4 channels) for discharge permit and water reuse safety;
  • Full-process Integration: One main unit supports up to 6 channels, covering multiple process stages while reducing procurement & maintenance costs.
When ordering, specify number of channels, parameter type per channel, measurement range, and cable length. Compatible only with digital water quality sensors.
🗣️ Customer Feedback
“The GWQ-MP200 multi-parameter analyzer has truly enabled us to implement feed-forward and feedback control. The linked control based on DO and ammonia has significantly reduced our aeration energy consumption. The touchscreen interface is intuitive, and operators mastered it within half a day. The data storage feature provides complete traceability for environmental inspections.” — Equipment Manager, WWTP, Jiangsu
