1. Introduction

The Water Quality Analysis Station integrates water quality detection, data transmission, and pretreatment units into a single system, supporting multiple water quality detection principles.

It enables simultaneous measurement of multiple water quality parameters, including ammonia nitrogen, COD, total phosphorus, total nitrogen, DO, turbidity, and ORP.

It is suitable for water quality monitoring in stormwater, sewage, black-odorous water bodies, rivers, lakes and other environments.

It employs 4G communication technology and is characterized by features such as easy installation, real-time data transmission, high detection accuracy, and stable operation.

2. Function

2.1 Automatic monitoring
According to the user's setting, the system can continuously, timely and accurately monitor the water quality of the target waters and its changes, and can obtain 7 × 24 hours continuous and stable online monitoring water quality data.

2.2 Automatic control

The system is capable of controlling devices such as water pumps, solenoid valves, air compressors, and analytical instruments to execute step-by-step control functions including pipeline water intake, distribution, analysis, cleaning, and backflushing.

2.3 Data Acquisition

The system is equipped with data extraction and acquisition capabilities, automatically archiving the collected data into a database in a standardized format.
2.4 Intuitive Display
On-site real-time display of instrument operational status and monitoring data can be achieved through LED touch screens and large display screens.
2.5 Automatic Alarm
The system automatically triggers alerts to the central station upon significant deviations in monitoring data, including but not limited to data anomalies, instrument status abnormalities, reagent depletion, and power failures.
2.6 Equipment Operation Status Management
The system features automatic operation, power outage protection, and power restoration functions.It supports checking and testing to facilitate routine maintenance and emergency troubleshooting.
2.7 Remote control
The system enables remote configuration of monitoring schedules and frequencies, data retrieval, and activation/deactivation of the automatic operation mode, among other remote control functionalities.
2.8 Data Processing
The monitoring center is capable of performing validity checks and real-time processing on the monitored data, storing it in the database in a standardized format. It can analyze and statistically process the data, conduct water quality assessments, and generate various charts and graphs in accordance with established standards.
2.9 Backflushing and Cleaning
The system performs pipeline backflushing during each analysis cycle, equipped with algae removal and sterilization functions.

3. Installation precautions

The following components should be pre-installed between the sampling point and instrument installation location: water pump, conduit, inlet pipe, outlet pipe, and overflow pipe.

The connecting pipelines should be selected according to specific conditions using rigid materials such as uPVC (unplasticized polyvinyl chloride) plastic, ABS engineering plastic, steel (metal pipes should not be used in areas with acidic or alkaline water quality), or stainless steel. To facilitate connection with the instrument, it is recommended to preferably use rigid PVC pipes for the pipelines.

Note:

1.The instrument mounting surface should be elevated above the tank wall. The pipeline should maintain a continuous downward slope from the instrument to the tank, with the following requirements:
*Minimize the number of pipe elbows.
*There should be no convex or concave in the pipeline.
*Avoid water accumulation in pipelines.
*Implement winter freeze protection measures.
2.Keep the pipeline clean and free of debris with a diameter greater than 2mm to prevent damage to the water pump or blockage of the pipeline.

3.The water flow at the pump installation location should be in a laminar state, and the pumped water should not be in an aerosol-like state (i.e., containing many air bubbles). The aerosol entering the instrument will result in measurement errors or alarms. The reason for the generation of aerosols in open channel drainage systems is that the water flow falls from a high place, carrying many bubbles into the water.
4.If a submersible pump is used, wrap an additional layer of stainless steel filter mesh around the original filter screen of the pump, with pore diameters between 1.0-2.0 mm. Pre-installed pipes should have all ports sealed to prevent debris or particles from entering. The submersible pump should be submerged in water as much as possible.
5.The pump and intake should be designed for easy maintenance, ensuring that large films (e.g., plastic sheets) clogging the intake can be conveniently removed.
