What is Turbidity?
Turbidity refers to the cloudiness or haziness of a fluid caused by large numbers of individual particles that are generally invisible to the naked eye. These particles may include sediments, microorganisms, organic matter, and pollutants suspended in water. Turbidity is an important indicator of water quality, as it can affect light penetration, photosynthesis in aquatic plants, and the health of ecosystems. High turbidity levels can be detrimental to aquatic life and may signal contamination. Measurement of turbidity is essential in water treatment processes and environmental monitoring, often expressed in Nephelometric Turbidity Units (NTU).
Why We Need to Measure Turbidity?
The turbidity of natural water bodies determines the quality of the growth environment of aquatic plants and animals, and is also one of the indispensable factors for warning of blue-green algae outbreaks. Turbidity affects the changes in underwater light intensity, the respiration and photosynthesis of aquatic plants and animals, and thus affects their growth environment.
Turbidity Sensor Working Principle
The Turbidity Sensor adopts optical technology to measure the turbidity of water by analyzing the scattering and absorption of light as it travels through the water. It comprises a light source, a receiver, and a measuring circuit. The light emitted by the source passes through the water, gets scattered and absorbed by suspended particles, and is then received by the receiver and converted into an electrical signal. The measuring circuit then calculates the turbidity of the water sample based on the strength of the electrical signal.

Chemical and Pharmaceutical: These sensors help maintain the clarity and quality of liquids used in chemical and pharmaceutical manufacturing processes, ensuring product consistency and safety.
Power and Energy: Turbidity sensors are used in power plants to monitor water quality in cooling systems and other processes, ensuring efficient operation and compliance with environmental regulations.
FAQs
1. Difference Between Turbidity and TSS
2. What is Good Level of Turbidity in Water?
Ideally turbidity should be kept below 1 NTU due to the effect of record keeping on disinfection. This is achievable in a large, well-run municipal water supply and should be able to achieve levels below 0.5 NTU prior to disinfection, averaging below 0.2 NTU or less, regardless of the type and quality of the source water.
