Turbidity in drinking water can be measured using a measuring device known as a turbidity meter. The turbidity meter is an electronic device that measures the degree of dispersion of small suspended particles in water. These particles can include minerals, sediment, suspended organic matter and bacteria. If there are too many suspended particles in the water, it can have a negative effect on the appearance and taste of the drinking water. These suspended particles can also actually cause color, taste and odor defects in the water. For these reasons, it is important to control turbidity to ensure good water quality.
This equipment uses a light known as radiant light to measure the degree of availability of suspended particles. The light enters the measuring tube and exits on the other side. Particles suspended in the water block the light and diminish it, measure the radiant light and calculate the degree of scattering.
Operation of the Turbidimeter
This equipment works by measuring the amount of scattered light that results from a high intensity light beam passing through a water sample. When a beam of light passes through a water sample, the light is scattered by the various components in the water, which include organic matter, suspended solids and minerals. The higher the level of light scattering, the less clear the water becomes. The measurement of the amount of scattered light is known as turbidity, and a turbidity meter is used to detect this level of turbidity.
In order to accurately measure the turbidity of a water sample, a turbidity meter is usually equipped with a set of lenses or a capsule. This is necessary to focus the light beam on the water sample. These lenses also help to prevent this light from being deflected, as the light beams would have difficulty passing through the sample if they were not properly focused.
A turbidity meter also includes a photodetector. The photodetector is a device that detects photons scattered by the water sample. This helps to accurately measure the amount of scattered light. Some turbidimeters have infrared light measuring devices that eliminate interference from visible light, giving a more accurate reading.
Use and Efficiency of the Turbidimeter
Turbidimeters can be used to verify the efficiency of water treatment plants. This is because treatment processes reduce the amount of suspended matter in the treated water. If a treatment plant is not working properly, the turbidity level should increase significantly. Therefore, the use of turbidity meters is a way to verify the efficiency of water treatment plants.
In addition, they can be used to establish upper or lower turbidity limits to ensure that water delivered to consumers is safe and of good quality. These limits are set according to international drinking water quality legislation. Governments set safe limits for turbidity, as turbidity that is too high can affect water quality and taste.
In general, turbidity meters are used to check the quality of drinking water by monitoring the degree of dispersion of particulate matter, sediment and suspended organic matter. This is done to determine if the turbidity level is within WHO safe limits. This is an integral part of water quality monitoring and control, and the results help ensure that drinking water delivered to consumers is free of impurities and dangerous contagious organisms.
