How to test water quality

Water quality rapid test kit

This is a portable testing tool that can quickly detect various pollutants in sewage, such as heavy metals, ammonia nitrogen, total phosphorus, etc. When using it, the staff only needs to follow the steps in the instructions, extract an appropriate amount of water sample from the sewage, add the water sample to the reagent tube, and then compare it with the color change and coloristic card to quickly get the test results. This method is easy to operate, easy to carry, and has a short test time. It is particularly suitable for on-site rapid testing.

Laboratory test

This is one of the commonly used methods in engineering water quality testing. First, it is necessary to collect water samples at a specified location and time, and then treat the collected water samples as required to remove impurities and factors that may affect the analysis results. Then, the treated samples are handed over to the laboratory for the determination of multiple indicators. Finally, the data after laboratory analysis will be analyzed and interpreted in detail, and the corresponding test report will be generated.

Phototypesetter determination

This is a commonly used water quality detection method, which can be made by measuring a series of standard solutions. When testing samples, the chromatically is obtained by phototypesetter determination. In addition, all glassware in contact with the sample must be cleaned with hydrochloride acid or solution, and finally washed or drained.

Residual chlorine detection

Residual chlorine detection is an important part of water quality detection. Water plants usually add a large amount of chlorine to disinfect and sterilize, so it is necessary to detect the residual chlorine content in the water. Common detection methods include calorimeter. By adding specific reagents, observing color changes and comparing with color cards, the residual chlorine content can be obtained.

Comprehensive water quality detection box

This is a device that integrates multiple detection functions. It can detect turbidity, residual chlorine, chlorine dioxide, pH, chromatically and other conventional water quality indicators. This detection box is usually powerful and reliable, and is suitable for environmental monitoring, water supply and drainage, disease prevention and control centers and other fields.
