Turbidity Test Apparatus FAQs
What is the working principle of Turbidity Test Fixtures?
The Turbidity Test Apparatus is mainly based on the principle of optical scattering, and calculates the turbidity value (unit: NTU, Nephelometric Turbidity Units) by measuring the degree of scattering or transmission of light by particles in water. Common measurement methods include:
90 ° scattering method (ISO 7027 standard): detects the intensity of scattered light at a 90 ° angle to the incident light, suitable for low turbidity water samples (040 NTU).
Transmission method: measures the degree of attenuation of light passing through a water sample, suitable for high turbidity water samples (>1000 NTU).
Ratio method (USEPA 180.1 standard): Combining scattered light and transmitted light data to improve measurement accuracy.
Why is Turbidity Test Apparatus necessary to monitor turbidity in drinking water and industrial water? What is the standard limit value?
Turbidity directly affects water quality safety and process efficiency:
Drinking water (WHO/EPA standard):
≤ 1 NTU (ideal value), ≤ 5 NTU (allowable limit).
High turbidity may mask pathogenic microorganisms (such as Cryptosporidium) and affect disinfection effectiveness.
Industrial water (such as pharmaceuticals, electronics):
Ultra pure water requires<0.1 NTU to prevent particle contamination of precision equipment.
Wastewater treatment discharge standards:
Usually requires<10 NTU (depending on regional regulations).
How to calibrate Turbidity Test Fixtures? How to choose calibration solution?
Calibration method:
Use standard turbidity solutions (such as Formazin or StablCal), with common concentrations including 0.02 NTU, 20 NTU, 100 NTU, and 800 NTU.
Perform multi-point calibration according to the instrument manual to ensure full range accuracy.
Calibration frequency:
Laboratory instruments: calibrated before each use.
Online monitoring device: calibrated weekly or monthly (depending on the usage environment).
Attention: Standard turbidity solution should be stored away from light and cannot be used after expiration.
What factors will affect the turbidity measurement results of Turbidity Test Apparatus? How to reduce errors?
Common interference factors and solutions:
Bubbles: Allow the water sample to settle or undergo ultrasonic degassing before measuring.
Chromaticity: Colored water samples may absorb light, and anti-interference optical systems (such as near-infrared light sources) should be selected.
Particle sedimentation: Shake the water sample evenly before measurement to avoid data drift.
Instrument contamination: Regularly clean the colorimetric dish or sensor window (using lint free cloth and pure water).
How to optimize water treatment process with online Turbidity Test Apparatus?
Waterworks: Real time monitoring of the turbidity of the filter effluent to ensure that the filtration effect meets the standard.
Wastewater treatment: Control the dosage of coagulants and optimize the efficiency of sedimentation tanks.
Industrial processes:
Pharmaceutical industry: monitoring the purity of water for injection (WFI).
Food and beverage: Ensure product clarity meets standards.
Intelligent linkage: Connected with automatic dosing system or alarm device to achieve closed-loop control.
