In order to determine the chemical oxygen demand (COD), the raw sample was diluted with distilled water to have a concentration of 0.3g/L [8]. Secondly, it was digested at 150°C for 2h in
2014/12/1 · Abstract. The objective for this paper was to develop a high throughput methodology to determine chemical oxygen demand (COD), five-day biochemical oxygen demand (BOD5) and other water quality parameters via turbidity measurements of the treated effluent that has residual suspended microalgae. This methodology has twin applicability and can be
2019/1/8 · Measuring chemical oxygen demand (COD) is one of the most frequently performed tests for assessing water quality. The test is widely applied in municipal wastewater facilities and industrial wastewater treatment plants to determine the degree of water
It is possible to calculate COD or BOD into standard personal units, 60 g of oxygen to decompose the organic compounds from one person per day or equaling of 135 g of oxygen to decompose Chemical Oxygen Demand (COD) in waste water (COD=2.25×BOD).
