A novel and quick method to avoid H2O2 interference on COD measurement in Fenton system by Na2SO3 reduction and O2 oxidation
Hydrogen peroxide interference on chemical oxygen demand (COD) measurement has been a big problem in the application of the Fenton process. However, there is no simple and effective method available to address this problem, although several methods have been reported in the literature. In this study, a new method has been developed based on Na2SO3 reduction and O2 oxidation, which has easy ...

Improved UV/O3 method for measuring the chemical oxygen demand
We improved the ultraviolet (UV)/O3-based method for measuring chemical oxygen demand (COD) in water. An on-line COD monitoring device was developed and the UV/O3 method was used to oxidize sample solutions. A model was established by using support vector machines (SVM) algorithm to estimate dissolved oxygen and CO2 in solutions. Based on the measured data by each sensor during the oxidation ...

Real-Time Organic Loading Monitoring for Municipal Wastewater Treatment
Summary Operational decisions can be difficult to make when incoming wastewater quality fluctuates. Industrial manufacturers can discharge highly concentrated wastewater unexpectedly causing operational problems if not detected. Aside from potential operational problems, shock loading also has the potential to affect regulatory compliance if wastewater cannot be treated properly. Monitoring ...
