BOD 5 – The Biochemical Oxygen Demand (BOD5) is a biological indicator of water pollution, specifically measuring the amount of oxygen consumed by microorganisms during the decomposition of organic matter over a period of 5 days. The average BOD5 value for household wastewater is typically around 300–400 mg/l, while for treated water, it is usually less than 30 mg/l.
PE – The Person Equivalent (PE) is a unit representing the pollution generated by one person, with an average wastewater production of about 150 litres/day and a BOD5 production of 60 grams/day.
