Determination of Chemical Oxygen Demand for Saline Wastewater
2010 4th International Conference on Bioinformatics and Biomedical Engineering, 2010The interference of the chloride ion (Cl-) on the standard method for chemical oxygen demand (COD) determination proposed by American Publican Health Association (APHA) cannot be ignored, especially for samples with high salinity. Increasing the ratio of HgSO4:Cl- and adding some masking agents such as AgNO3, Cr3+, Al3+ are all good modifications of ...

Journal of the Science of Food and Agriculture, 1983
AbstractClose, largely linear, relationships were found between volatile fatty acids (VFA) determined by gas chromatography, total organic acids (TOA) determined colorimetrically, biochemical oxygen demand (BOD5) and chemical oxygen demand (COD) in the soluble fraction of piggery slurries.

Chemical oxygen demand reduction in a whey fermentation
European Journal of Applied Microbiology and Biotechnology, 1980The efficiency of Chemical Oxygen Demand (COD) reduction η in the fermentation of whey by Kluyveromyces fragilis IMAT 1872 was studied at various temperatures, lactose concentrations, air dilution ratios and stirring speeds. Their effects on the biomass yield (y) has been determined previously (Moresi et al. in press).

An automated system for the determination of chemical oxygen demand
Water Research, 1969Abstract Measured volumes of sample, mercuric sulphate and potassium dichromate/ sulphuric acid digestant are metered into a mixing pot. The mixed solution is pumped through a 40 ft length of glass coil suspended in a fluidized sand bath heated to 160°C.
