What Factors Affect Turbidity Measurements

by:BOQU     2023-03-15
It is very important in the process of water quality testing for each parameter, and turbidity is one of the more representative test items in practice. Anyone familiar with turbidity knows that turbidity is an optical property that can be measured with a spectrophotometer. Ordinary water quality detectors can analyze the parameters of solid substances in water through light wave refractometers. Suspended particles in water can prevent the calculation of transmittance to obtain accurate water quality turbidity data, but as long as they are measured, there will be interference. So what factors affect turbidity measurement? What is turbidity measurement? There are three modern turbidity measurement methods, two of which are the total suspended solids method, and the commonly used ones are the turbidity meter and the Doppler method, whose advantages lie in the range and accuracy of turbidity measurement. Generally, the turbidity parameters obtained by the water quality detector can be used to evaluate the water quality or the efficiency of the water filtration process. Turbidity measurement is an important indicator in many industries and applications. It not only directly affects the output of industrial production, but also affects the institutional factors caused by detection. What factors affect turbidimetry? 1. Bubbles will also interfere with the online detection of water turbidity. In this case, we can choose an appropriate installation point to reduce air bubble interference. 2. During the detection process of the water turbidity detector, scattered light is used to determine the velocity of particles suspended in the liquid medium. Astigmatism depends on the concentration of particles and the horizontal scattering of particles. Second, the shape and size of the particles: the particles are smaller than the wavelength of visible light, and the symmetry of scattered light is 1/10 smaller. Larger particles (typically larger in diameter than the wavelength of visible light) asymmetrically scatter light, and the scattering angle must be taken into account in the determination of turbidity. 3. Wavelength. The intensity of the scattered light depends on the size of the particle. And whether the color of the liquid will reduce the amount of light, this will also affect the turbidity parameter. 4. When implementing the turbidity determination method, you can refer to the detection range. For example, many wineries need to detect yeast particles in liquid yellow water. Therefore, when testing, the angle and absorption of the light source must be considered. When turbidity is detected, some absorbing substances and fluorescence in the water quality will have an influence. However, in motion, this interference can be kept to a minimum by wavelengths other than visible light. The above is about which factors will affect the measurement of turbidity? Which multi-parameter water quality analyzer is a good introduction, I hope it will be helpful to everyone. When using a water quality detector, you must pay attention to the turbidity of the interference to ensure the accuracy of the turbidity parameters.
