Water Quality Online Monitoring Comprehensive Solution

Solution Overview

Water quality safety is the lifeline of urban water supply, industrial processes, and environmental protection. With increasingly stringent standards such as the EU Drinking Water Directive and US EPA regulations, traditional manual sampling plus laboratory testing can no longer meet the demands of real-time monitoring and rapid response.

This Water Quality Online Monitoring Comprehensive Solution leverages Ecolor Tech's full range of online water quality instruments — including conductivity meters, pH/ORP analyzers, dissolved oxygen electrodes, flow-through turbidity meters, submersible turbidity sensors, sludge concentration meters, online residual chlorine analyzers, and compact water quality monitoring stations — to build a comprehensive monitoring system from source water to distribution network endpoints.

System Architecture

The system follows a four-tier architecture: Perception → Transmission → Platform → Application.

Perception Layer

Multi-parameter water quality instruments deployed at monitoring points:

• Conductivity Meter: Monitors ionic concentration, reflecting total dissolved solids
• pH/ORP Analyzer: Monitors acidity/alkalinity and oxidation-reduction potential
• Dissolved Oxygen Electrode: Monitors dissolved oxygen levels
• Flow-through/Submersible Turbidity Meter: Monitors water turbidity
• Sludge Concentration Meter: Monitors activated sludge concentration
• Online Residual Chlorine Analyzer: Monitors disinfectant residual
• Compact Water Quality Station: Integrated multi-parameter monitoring

Transmission Layer

Hero V9 Series RTU (EC32/EC60) for data acquisition, protocol conversion, and 4G/5G/NB-IoT wireless transmission.

Platform Layer

Cloud-based water quality monitoring platform for data aggregation, storage, analysis, and visualization.

Application Layer

Real-time monitoring dashboard, anomaly alerts, trend analysis, report generation, and mobile app.

Typical Application Scenarios

1. Source Water Monitoring: Deploy multi-parameter stations at river, lake, and reservoir intakes for real-time raw water quality tracking.
2. Water Treatment Plant Process Control: Deploy online instruments at coagulation, sedimentation, filtration, and disinfection stages for fine-tuned operation.
3. Distribution Network Endpoint Monitoring: Deploy compact stations at key network nodes to ensure tap water compliance.
4. Wastewater Treatment Plant Monitoring: Deploy DO, sludge concentration, and turbidity instruments at biological tanks, secondary clarifiers, and effluent outlets.
5. Industrial Effluent Online Monitoring: Deploy monitoring stations at enterprise discharge outlets for compliance monitoring.
6. Black-Odor Water Body Treatment Monitoring: Deploy multi-parameter monitoring at river treatment sections to evaluate remediation effectiveness.

Solution Advantages
