Tailored Water Quality Measurement from Waste Water and Drinking Water to Environmental Monitoring
Wastewater Treatment: AAO Process Efficiency
The AAO (Anaerobic-Aerobic-Oxic) process is a biological treatment method used in wastewater treatment, combining anaerobic, anoxic, and Oxic (aerobic) stages to remove organic matter, nitrogen and phosphorus.
In the anaerobic stage, bacteria break down organic pollutants without oxygen, producing methane and volatile fatty acids. In the anoxic stage, nitrate serves as the electron acceptor for denitrifying bacteria to reduce nitrogen levels. Finally, in the aerobic stage, oxygen is introduced to support the growth of aerobic microorganisms that further degrade organic material and promote the nitrification process, converting ammonia into nitrate. This integrated approach effectively treats wastewater by addressing both nutrient removal and organic matter degradation.
​
Real-time monitoring using the Online UV Nitrate Monitoring System and Online UV254 Sensor for COD significantly improves control in the AAO process. These instruments provide accurate, continuous data that allows operators to fine-tune aeration and carbon dosing for better efficiency and performance.
​
-
Online UV Nitrate Monitoring enables precise nitrate control in anoxic and oxic zones, reducing aeration energy use and optimizing carbon addition for denitrification.
-
Online UV254 for COD offers early detection of organic load changes, supporting stable biological conditions and preventing over- or under-dosing of carbon.
​
Together, these technologies lead to lower operating costs, improved nutrient removal, and a more sustainable wastewater treatment process.


Monitor Drinking Water: UV for measuring Organic Material
UV254 is used to measure UV Transmission and UV Absorbance in drinking water. This real-time measurement allows water treatment operators continuous insight into the organic load. This helps control the formation of disinfection by-products (DBPs) and ensures the safe distribution of drinking water throughout the network.
Typical locations where UV254 is sited:
​
-
Raw Water Intake: UV254 is measured at the intake point to assess the quality of the source water, identifying the presence of organic contaminants that may require preliminary treatment.
-
Pre-treatment or Coagulation Stage: In this stage, UV254 can help determine the effectiveness of coagulation and flocculation processes in removing organic matter before further treatment.
-
Before and After UV Disinfection: UV254 is monitored before and after UV disinfection systems to ensure that the disinfection process is effectively reducing organic matter and pathogens in the water.
-
Final Drinking Water Output: Measuring UV254 in the treated water before distribution helps confirm that the water meets safety standards and is free from harmful organic substances and microorganisms.
​
By placing UV254 sensors at these critical points, water treatment plants can efficiently manage organic contamination levels, optimize treatment processes, and ensure the delivery of clean and safe drinking water.
