What are the applications of the water quality analyzer?

The online water quality analysis instruments currently on the market mainly include monitoring online water quality analysis instruments and process type online water quality analysis instruments. The difference between the two is mainly that the monitoring type online water quality analysis requires high accuracy and timeliness of measurement data. It is mainly used to monitor the decision-making basis of the department; while the process-based online water quality analysis requires high reliability, stability and accuracy of the data, and is mostly used for technical monitoring and guidance. Application of water quality analyzers.

Field water pollution monitoring

Especially in the downstream of industrial parks, multiple water quality online monitoring stations should be set up. The detection of the chemical composition of water in the water and the content of each major component can instantly reflect the changes in water quality in the waters. In order to save work and improve work efficiency, multiple samples of water quality in the waters can be pre-analyzed and tested, and the main components (generally referred to as harmful components of polluted water, such as heavy metals, sulfur and phosphorus, etc.) Substances, organic non-degradable poisons and others are identified and targeted monitoring of the components being marked using a monitoring online water quality analysis instrument. Of course, in order to ensure the comprehensiveness of water quality monitoring, one or two online water quality analysis instruments are needed to monitor the water quality of all aspects.

Industrial treatment of production wastewater

In the sewage treatment production process, since the treated sewage is used inconsistently (generally in the natural environment or in repeated production), the final parameter settings are different (the treatment requirements for recycling are relatively high). However, in the selection of water quality analysis instruments, the process type online water quality analysis instrument uses the method directly installed on the production system to dynamically reflect the change of water quality in the water treatment system. Of course, the content and scope of the detection analysis at this time are relatively It is more complicated, and should be interlocked with the parameter alarm system to provide instant technical parameter reference for the immediate production operation and the next step of processing through the abnormal fluctuation of water quality components.

Drinking water quality monitoring

The analysis and monitoring of drinking water quality of urban and rural residents is different. For the vast rural areas, especially in North China, the drinking water source generally comes from the groundwater body. It can realize the online water quality monitoring of the groundwater in the surface rivers, lakes and other waters in the region. Real-time monitoring and analysis of water quality. However, for urban residents who use tap water collective water supply, the monitoring of drinking water quality is generally carried out before the factory water pipeline of the waterworks. In some areas, there are also applications of online monitoring instruments in the water pipeline, but the cost is relatively high. In general, there is no major fluctuation or change in the water quality in the tap water pipeline. The online water quality monitoring carried out in the waterworks is the same as the industrial production water treatment monitoring. The instruments are installed in the system, and the alarm is monitored by real-time analysis of the water quality in the system to ensure the water quality. However, since the purpose of the water plant is to drink, the parameters of each component are relatively strict, and the range is relatively wide, and the requirements for water hardness and salt content are relatively high.

Portable online water quality analysis instrument

The portable online water quality analysis instrument is relatively small in size, and has the characteristics of dustproof, waterproof, strong, light weight, corrosion resistance, and easy operation. It is very suitable for special water quality analysis tasks in the field and daily random monitoring and analysis tasks. Its application range is relatively wide, it can not only detect and analyze water quality in the field, but also detect water supply in tap water in residents' homes. However, its accuracy is generally relatively low, which is the main reason why portable online water quality analysis instruments cannot be used as professional industrial water treatment technology.
