Determination of the chemical oxygen demand (COD) using a copper electrode: a clean alternative method
(Springer, 2009-05-01)
A clean alternative method for the determination of chemical oxygen demand (COD) was developed using a copper electrode as an electrocatalytic sensor. The measuring principle is based on oxidation current of organic compounds ...

Cost-effective removal of COD in the pre-treatment of wastewater from the paper industry
(IWA Publishing, 2020-04)
The present paper reveals results of research for cost-effective removal of chemical oxygen demand (COD) contained in industrial paper mill effluent. Not only process efficiency but also wastewater treatment costs are ...
Black water treatment by an upflow anaerobic sludge blanket (UASB) reactor: A pilot study
(2019-10-15)
Decentralized sanitary wastewater treatment has become a viable and sustainable alternative, especially for developing countries and small communities. Besides, effluents may present variations in chemical oxygen demand ...
Performance Evaluation of First-Order Hydraulic Models for COD Removal in Horizontal Subsurface-Flow Constructed Wetlands
(Asce-amer Soc Civil Engineers, 2017-10-01)
The aims of the present study are to verify the performance of four first-order hydraulic models and identify the model that best described the kinetics of the chemical oxygen demand (COD) removal in constructed wetlands. ...
Influence of the nutrient concentrations of whey on ethanol and biomass production and COD reduction
(Univ Estadual Maringa, Pro-reitoria Pesquisa Pos-graduacao, 2017-01-01)
The present study aimed at the use of cheese whey as substrate for ethanol production by Kluyveromyces marxianus. The effect of the initial cheese whey concentration (M1 57.60; M2 45.60; M3 32.50 and M4 18.80 g L-1) on the ...
