new product online water quality test monitor

- Aug 24, 2020-

1. Background:

 

Drinking water safety is an important basic condition for the sustainable development of modern cities. High-quality and safe drinking water and reliable supply are the foundation for building a healthy club and promoting economic development. The quality of drinking water in today's society has become an important factor restricting the further development of the economy and affecting social stability. Since July 1, 2012, my country has enforced the new version of the "Sanitary Standards for Drinking Water", with as many as 106 new national standard testing indicators. Previously, tap water was only tested for factory indicators. The new national standard requires that the end water and secondary water supply also meet the standards.

Under the current situation of lack of professional management, unsupervised pollution of secondary water supply water quality, and unmaintained water supply facilities and over-age service, how to strengthen the monitoring of secondary water supply water quality and provide residents with safe water supply is an urgent problem to be solved.

 

2. Purpose

 

This scheme is to realize online monitoring of water quality parameters in the process of storing pressurized water supply in the secondary water supply plant, ensuring the safe and reliable operation of the entire water supply system, while optimizing the process, accurately controlling the dosage of the dosing equipment, and reducing labor costs. Invest to achieve the purpose of economic operation.

3, the basic parameters of secondary water supply detection

1.PH

Too low a pH value will corrode water pipes, and too high a pH value will cause the precipitation of dissolved salts and reduce the chlorination and disinfection effect. At the same time, long-term drinking of water with too low or too high pH will also have a certain impact on human physiological health.

 

2. Residual chlorine

If the factory water does not contain chlorine or the amount of chlorine added is not enough, bacteria, E. coli and other microorganisms may multiply in the pipe network, which will affect the water quality of the pipe network. Therefore, a certain amount of residual chlorine must be guaranteed in the water supply pipe network. Therefore, a certain amount of residual chlorine must be maintained in municipal tap water to ensure the safety of drinking water microbiological indicators.

 

3. Turbidity

Turbidity is a vital indicator for water quality. While reducing turbidity, it also reduces bacteria, coliforms, viruses, cryptosporidium, iron, manganese, etc. in the water. Studies have shown that when the turbidity in water is 2.5NTU, the organic matter in the water is removed by 27.3%, when the turbidity is reduced to 0.5NTU, the organic matter is removed by 79.6%, and when the turbidity is 0.1NTU, most of the organic matter is removed, causing disease The content of microorganisms is also greatly reduced. Especially for the tap water industry, the turbidity index is very critical.

 

4, system composition

 

1. Monitoring Center:

Main hardware: cloud server, GPRS data transmission module, computer, etc.

Main software: real-time query APP client

 

2. Communication network: China Mobile GPRS-VPN private network.

 

3. Measurement and control terminal: water quality measurement and control terminal,

 

4. Measuring equipment: online water quality monitoring instrument

 

 

5, characteristics

 

1. Real-time monitoring of water quality and real-time fluctuations of water temperature, pH, residual chlorine and turbidity.

 

2. With RS485 communication interface, it is convenient for on-site users to manage and view data on the upper computer in real time.

 

3. The system consists of sensors/electrodes, transmitters (instruments), wireless modules and other equipment

 

4. Remote monitoring of data, which can monitor data in a short-distance cable, or use the Internet for alarm notification and data transmission through wireless modules such as wifi and gprs. Computers or mobile devices can remotely monitor the corresponding tap water pipe network monitoring points in real-time online through relevant software (such as host computer software system, mobile phone APP), and can remotely connect with the corresponding supervision department. It is convenient for users to receive alarms and store and read related data in time at the remote end.
