The Importance of Turbidity and Why You Should Measure It


Turbidity describes the cloudiness or haziness of water and can have both beneficial and detrimental effects on the environment, as well as human health. In water testing, turbidity can be an important indicator of water quality. But what is turbidity? Why should you even care about turbidity? Here’s everything you need to know about turbidity and why you should measure it using turbidity analysers.

What is Turbidity?

Turbidity is a measurement of the cloudiness or haziness in a liquid. In other words, it’s the level to which particles suspended in the water obscure light passing through. Any suspension (including organics like soil or microorganisms) creates turbidity, but larger particles have more impact than smaller ones.

The goal is to remove these particles so they don’t interfere with drinking water purification, whether that’s via filtration, distillation, ultraviolet radiation, or chlorination. This involves setting a high threshold for turbidity so you can get rid of any initial contamination in your source water before you start purifying it into drinking water.

Increased turbidity can occur when larger particles enter the water, such as sand or silt. And when this occurs it not only reduces the clarity of the water but also prevents light from penetrating as deeply, which can affect photosynthesis at lower depths and hamper fish spawning. When you measure turbidity in your water source using turbidity analysers, you are able to identify potential causes for increased turbidity and make adjustments if necessary.

How to Measure Turbidity?

If you want to measure turbidity, you’ll need to purchase a turbidity analyser. Once you’ve purchased the analyser, you can go about collecting your sample and. The analysis is relatively quick – it takes less than a minute – and will produce an accurate reading on what is known as Nephelometric Turbidity Units (NTU).

How Can We Reduce Turbidity?

Sometimes, turbidity can be reduced by finding the source of the problem. Too much turbidity in water can be caused by chemical or natural constituents. If it is an unnatural cause, consult with a qualified water testing professional to discover the nature of the impurity. If it is from a natural source, such as soil runoff or sediment from erosion, then working on changing these factors may help reduce turbidity levels. However, if you are unsure about the origin of your water’s turbidity levels, contact your local utility company for assistance.

Why Measure Turbidity for Drinking Water Treatment?

Turbidity meters is as much as important as a broken bag detector. Turbidity measurement tells how clear the water is. Higher turbidity readings can be an indication that there are solids in the water, which are often sources for organisms that can cause disease. Additionally, higher turbidity readings mean disinfection will be less effective. If you notice turbidity spikes, try to identify what may have caused them.

Turbidity, or the cloudiness of water, can be an important factor in determining its suitability for a particular use. It’s important to find equipment that gives precise and accurate results so that it can be used to make important decisions about water quality. Deal with suppliers offering high quality systems such as turbidity meters, industrial sirens and beacons, and more.
