How to measure the pH turbidity chlorine value for secondary water supply?

2023,07,31

The secondary water supply of domestic drinking water refers to the form of water supply that transfers tap water to users for daily drinking through water storage equipment and pressurization and water purification facilities. The secondary water supply is mainly established to make up for the lack of pressure in municipal water supply pipelines and to ensure water use for high-rise people. Compared with raw water supply, the water quality of secondary water supply is more likely to be polluted because it has to go through more links. Therefore, it is very important to test and manage the drinking water quality of the secondary water supply.

Sampling points are generally set at the raw water inlet, equipment outlet, terminal water
Required items: color, turbidity, smell, taste and visible matter, pH, coliform group, total number of bacteria, residual chlorine
Optional test items: total hardness, chloride, nitrate nitrogen, volatile phenol, cyanide, arsenic, six prices, iron, manganese, lead, ultraviolet intensity.

Additional measurement items: ammonia nitrogen, nitrite nitrogen, oxygen consumption

pH chlorine turbidity sensor

The multi-parameter water quality analysis instrument developed and produced by Delfino can continuously monitor water quality pH, temperature, turbidity and residual chlorine value. MCC200 is a multi-parameter controller that can connect 2-4 identical or different digital sensors at the same time to realize water quality analysis. Real-time monitoring of multiple parameters. It comes with a RS485 digital communication and supports Modbus communication protocol. If customers need current and relays, we have matching external expansion modules, which are easy to use. The sensors used in the secondary water supply multi-parameter scheme are also digital. Digital pH Sensor, with PPS shell, IP68 protection level, long service life. The low Turbidity Sensor adopts the laser method and can measure the turbidity value in the range of 0~100NTU. The film-covered amperometric system adopted by the residual Chlorine Sensor has a long service life and low maintenance. In addition to the use of electrolyte, it does not need to consume chemical reagents.
