Chemical Oxygen Demand and BOD in Dyehouse Effluent
topic
COD analysis of textile effluent uses dichromate oxidation in refluxed acidic solution followed by titrimetric or photometric endpoint detection, while BOD5 measures oxygen consumption by microbial oxidation over five days at 20 degrees Celsius; COD to BOD ratio characterises the biodegradability of effluent organic load and determines suitability for biological wastewater treatment.
Role
Provides the primary organic pollution load parameters that govern wastewater treatment plant performance design, compliance monitoring against discharge consent conditions, and assessment of in-plant cleaner production measures that reduce the organic load from textile dyeing and finishing operations entering receiving water bodies.
