Micro Water Quality Monitoring Station

Micro water quality monitoring station is a facility used for real-time monitoring of water  quality, typically deployed on the shores of rivers, lakes, reservoirs, and other water bodies. Its primary function is to continuously monitor and collect data on water quality parameters, enabling timely understanding of water quality changes and providing a scientific basis for water environmental protection and management.

I. Main Components

1. Sensor System

Conventional Parameter Sensors: Such as pH, dissolved oxygen (DO), conductivity, turbidity, temperature, etc.

Nutrient Sensors: Such as ammonia nitrogen, nitrate, phosphate, etc.

Organic Matter Sensors: Such as chemical oxygen demand (COD), total organic carbon (TOC), etc.

2. Data Acquisition and Transmission System

Data Logger: Responsible for collecting sensor data and performing preliminary processing.

Communication Module: Transmits data to the data center via wired or wireless methods (e.g., 4G, 5G).

3. Power Supply System

Grid Power Supply: Typically used if the shore station is close to the power grid.

Solar Power Supply: In remote areas, usually equipped with solar panels and batteries.

4. Data Processing and Storage System

Local Storage: Used for temporary data storage to prevent data loss during network interruptions.

Remote Data Center: Used for long-term data storage and analysis.

5. Auxiliary Equipment

Weather Station: Monitors meteorological parameters such as wind speed, wind direction, and rainfall to assist in analyzing water quality changes.

Video Surveillance: Used for real-time monitoring of the surrounding environment to prevent vandalism.

II. Main Functions

1. Real-Time Monitoring:

Continuously monitors water quality parameters to promptly detect abnormal conditions.

2. Data Storage and Analysis:

Stores historical data for trend analysis and early warning.

3. Remote Control:

Allows parameter configuration and equipment maintenance through a remote management system.

4. Early Warning and Alarm:  

Automatically issues warnings or alerts when water quality parameters exceed preset thresholds.

Micro water quality monitoring stations play a crucial role in water environmental protection and resource management. Through real-time monitoring and data analysis, they effectively prevent and respond to water pollution incidents, ensuring the sustainable utilization of water resources.

III. Application

1.Environmental Monitoring:  

Used to monitor the water quality of natural water bodies and assess the health status of the water environment.

2. Drinking Water Source Protection:  

Monitors the water quality of drinking water sources to ensure the safety of water supply.

3. Industrial Wastewater Discharge Monitoring:  

Monitors the water quality near industrial areas to prevent pollution incidents.

4. Aquaculture:  

Monitors the water quality of aquaculture systems to ensure the healthy growth of aquatic products.

IV. Advantages

1. Real-Time Capability:

Provides real-time water quality data, enabling rapid response.

2. Automation:

Reduces the need for manual intervention and lowers operational costs.

3. Multi-Functionality:

Can simultaneously monitor multiple water quality parameters, offering comprehensive water quality information.

4. Remote Management:

Enables remote monitoring and management via the internet, improving management efficiency.

V. Challenge

1. Equipment maintenance:

Senors require regular calibration and maintenance to ensure data accuracy.

2. Environmental adaptability:

Equipment needs to be able to adapt to a variety of harsh environmental conditions, such as high temperature, low temperature, humidity, etc.

3. Data security:

It is necessary to ensure the security of data transmission and storage to prevent data leakage or tampering.
