In the context of increasingly severe water pollution in Vietnam, monitoring the quality of effluent wastewater is a mandatory requirement for industrial wastewater treatment plants.
The ColorVis 705 IQ color sensor from WTW (A Xylem Brand) is an advanced device that enables continuous and accurate water quality monitoring, helping businesses comply with environmental regulations such as QCVN 40:2011/BTNMT..
This article will provide a detailed introduction to this sensor, its outstanding features, and ways to optimize wastewater treatment processes using modern technology.
To meet the current demand for continuous and accurate water quality monitoring, Viet An introduces the ColorVis 705 IQ color sensor (WTW - A Xylem Brand)to our valued customers. This sensor is specifically designed for use in wastewater treatment plants and surface water monitoring, providing direct and continuous measurements without the need for reagents.
The Importance of Wastewater Monitoring and Color Measurement
The color of wastewater is a critical parameter that reflects the level of organic and chemical pollution. Measuring water color helps to:
- Detect early changes in wastewater quality.
- Evaluate the effectiveness of wastewater treatment systems.
- Ensure that effluent wastewater meets discharge standards as per Vietnamese legal regulations.
The ColorVis 705 IQ is designed to measure color, COD (Chemical Oxygen Demand), TSS (Total Suspended Solids), and Nitrate (NO3), making it an ideal solution for wastewater treatment plants, industrial zones, and surface water monitoring.
Outstanding Features of the ColorVis 705 IQ
- High-precision color measurement with turbidity compensation.
- Monitoring of COD (Chemical Oxygen Demand), NO3 (Nitrate), TSS (Total Suspended Solids), and color using a single sensor (with the advanced version).
- Made from high-quality materials: Titanium and PEEK.
- Integrated ultrasonic cleaning system to reduce maintenance and costs.
Measurement Method and Operating Principle
The ColorVis 705 IQ employs UV-VIS optical technology, measuring light absorption at various wavelengths (from 200 nm to 720 nm) to determine parameters such as color, COD, TSS, and Nitrate. The operating principle includes:
- Sample filtration: Removes large impurities to ensure measurement accuracy.
- Light absorption measurement:The sensor automatically selects the appropriate wavelength (in accordance with ISO 7887, , Hazen standards).).
- Turbidity compensation:The compensation feature uses a reference wavelength to eliminate the impact of turbidity, providing results in True Color (TC) or Apparent Color (AC).
- Data conversion:Results are displayed in mg/l Pt/Co or other units depending on the parameter.
This technology ensures direct and continuous measurement,suitable for , suitable for automated wastewater monitoring. in Vietnam.
When measuring, the water sample needs to be filtered to remove large impurities. However, with the UV-VIS optical sensor’s measurement technology,the turbidity compensation method delivers more accurate results, compatible with laboratory measurements.
When the turbidity compensation feature is activated, the sensor subtracts the absorption at the highest wavelength from the measured wavelength, thereby converting the results into mg/l Pt/Co units and displaying them as True Color (TC).
If the turbidity compensation feature is not used, the sensor only measures absorption at the selected wavelength and converts it into Apparent Color (AC).
