Daily BOD5 pollution load (kg/d
Daily BOD5 pollution load (kg/d): …
biological oxygen demand for 5 days (BOD5
Evaluation of outflow values BOD5 (mg/l
Certificated performance EN 12566-3 (up to 98% BOD5)
Biochemical oxygen demand (BOD5 at 20° C) without nitrification (2)
By definition, one population equivalent equals 60 g of BOD5 per day.
BOD5 measures the quantity of biodegradable organic matter contained in water.
By definition, one population equivalent corresponds to 60 g of BOD5 per day.
Average Influent Biological Oxygen Demand (BOD5) is the BOD5 concentration of wastewater when it is entering a Wastewater Treatment Plant to be treated.
Obtains the value equivalent to BOD5 in just 90 min.
BOD5 measures the quantity of biodegradable organic matter contained in water.
The BOD5 loading injected (unless otherwise specified, the expression BOD must be construed as BOD5) into urban wastewater per inhabitant and per day can be estimated, after pre-treatment, as follows :
(Example: a treatment plant of 1000 p.e. receives 60 kg BOD5/day).
Notes on determining biochemical oxygen demand after five days (BOD5) in 24h composite samples
The value of COD or BOD5 at the end of the experiment is to be compared to wastewater discharge standards (usually COD = 180 mgO2/l , BOD5 = 70 mgO2/l).
BOD is commonly reported as BOD5, the amount of oxygen consumed over a 5-day period of incubation.
an essentially organic and easily biodegradable organic content identified by COD/BOD5 ratios < 2;
Conventionally, BOD5 is used, or in other words the quantity of oxygen consumed after five days of incubation.
