1. Water quality testing
The purpose of water testing is to assess the levels of contaminants in water to ensure it meets health standards. It mainly includes the following steps:
Sample collection: Collect water samples from different locations and time points to ensure that the samples are representative.
Laboratory analysis: water samples are analyzed using physical, chemical and microbiological methods, including testing for the following:
Chemical composition: Detection of heavy metals (such as lead, arsenic), chlorides, nitrates, etc.
pH: A measure of the acidity or alkalinity of water.
Suspended Matter: Assess the concentration of solid particles in water.
Bacteria and Pathogens: Detects bacteria (such as E. coli) in water.

2. Water treatment
Based on the test results, implement appropriate water quality treatment methods. Common water treatment technologies include:
Physical treatment:
Filtration: Use filters to remove suspended matter and solid particles from water.
Sedimentation: Removal of solid contaminants from water by gravity settling.

Chemical treatment:
Disinfection: Use of chlorine, ozone or ultraviolet light to kill microorganisms in water.
Coagulation and flocculation: The use of chemical coagulation agents to cause suspended matter to aggregate into larger particles for easier removal.

Biological treatment:
Activated sludge method: uses microorganisms to decompose organic matter in water, often used in wastewater treatment.
Biofilter: Uses microorganisms to grow on a carrier to remove pollutants from water.

3. Continuous monitoring
Regular testing: Install water quality monitoring equipment to regularly check the chemical and microbiological indicators of the water.
Data Analysis: Use data analysis techniques to evaluate water quality trends and identify and address potential problems in a timely manner.

4. Compliance with laws and regulations
Ensure all water testing and treatment processes comply with local and international standards to protect public health and the environment.

Water quality testing and treatment not only concerns the safety of drinking water, but also involves the sustainable use of water resources. If you are interested in any specific technology or process, or have other related questions, feel free to let us know!
