Continuous Water Quality Monitoring: The YSI UVT-254 Sensor for IQ SensorNet Systems
Real-Time Insights for Efficient Wastewater Treatment

The YSI UVT-254 sensor represents a powerful advancement in continuous water quality monitoring for wastewater treatment facilities. This innovative probe, designed for the IQ SensorNet system, offers a robust and reagentless solution for measuring critical parameters directly within the process stream. By eliminating the need for sample collection and chemical analysis, the YSI UVT-254 sensor empowers operators with real-time data, leading to more efficient and cost-effective disinfection processes.

Unveiling Key Water Quality Indicators

The YSI UVT-254 sensor utilizes a sophisticated optical approach to measure two key parameters:

UV Transmittance at 254 nm (UVT-254): This measurement quantifies the amount of ultraviolet light (specifically at a wavelength of 254 nanometers) that can transmit through the water sample. Lower UVT-254 values indicate higher levels of organic matter present, which can hinder disinfection effectiveness.

Spectral Absorption Coefficient (SAC): This parameter reflects the overall absorption of light by organic matter in the water. The YSI UVT-254 sensor provides readings for both total SAC and soluble SAC, offering a more comprehensive picture of the organic load.

Beyond Direct Measurements: Correlated Insights for Process Optimization

The power of the YSI UVT-254 sensor extends beyond direct measurements. By leveraging sophisticated algorithms, the sensor can provide valuable correlated data for several crucial water quality indicators:

Biological Oxygen Demand (BOD): This parameter reflects the amount of dissolved oxygen consumed by microorganisms in the water as they break down organic matter. Estimating BOD through the YSI UVT-254 sensor allows for proactive adjustments to optimize the biological treatment process.

Chemical Oxygen Demand (COD): This measurement indicates the total amount of organic matter present in the water, both biodegradable and non-biodegradable. Correlated COD data from the YSI UVT-254 sensor provides insights into the overall treatment efficiency and potential pollutant discharge.

Total Organic Carbon (TOC): This parameter quantifies the total amount of organic carbon present in the water. The YSI UVT-254 sensor can estimate TOC, aiding in monitoring the effectiveness of organic matter removal throughout the treatment process.

Dissolved Organic Carbon (DOC): This measurement focuses specifically on the dissolved fraction of organic carbon in the water. Correlated DOC data from the YSI UVT-254 sensor offers valuable information for optimizing treatment processes targeting dissolved organic matter removal.

Optimizing Disinfection Efficiency

The UVT-254 measurement provided by the YSI UVT-254 sensor plays a critical role in optimizing ultraviolet (UV) disinfection processes. UV light is a widely used method for inactivating harmful microorganisms in wastewater. By understanding the UV transmittance of the water, operators can determine the optimal UV light intensity and contact time required for effective disinfection. This real-time data ensures proper disinfection while minimizing energy consumption and operational costs.

Built for Durability and Ease of Use

The YSI UVT-254 sensor is encased in a rugged, corrosion-resistant field probe, ensuring reliable performance in harsh wastewater environments. The sensor utilizes high-tech materials like titanium and PEEK for maximum durability. Additionally, the innovative UltraClean® ultrasonic cleaning technology minimizes maintenance needs by automatically preventing biofouling buildup on the sensor’s optical components. This translates to less downtime and reduced maintenance costs.

Seamless Integration with IQ SensorNet System

The YSI UVT-254 sensor seamlessly integrates with the IQ SensorNet system, a comprehensive wastewater process monitoring platform. Data from the sensor can be transmitted to either the IQ SensorNet 2020 3G controller (for advanced data acquisition and remote access) or the simplified IQ SensorNet 282/284 controllers, depending on facility needs. This integrated approach provides a centralized hub for monitoring and analyzing critical water quality parameters, empowering operators to make informed decisions for efficient wastewater treatment.

Conclusion: The YSI UVT-254 Sensor – A Game Changer for Wastewater Treatment

The YSI UVT-254 sensor represents a significant advancement in wastewater treatment process control. By offering real-time, continuous measurements and correlated data for key water quality parameters, this innovative sensor empowers operators to optimize treatment processes, ensure efficient disinfection, and ultimately achieve regulatory compliance. With its robust design, ease of use, and seamless integration with the IQ SensorNet system, the YSI UVT-254 sensor positions itself as a valuable tool for any facility seeking to enhance their wastewater treatment operations.
