5 = 200–250 mg/l), whereas in tropical countries the wastewater is strong (BOD. 5. = 300–700 mg/l) as the water consumption is typically much lower (40–100 l/person day). The other factor determining the strength of domestic wastewater is the BOD (= amount of organic waste) produced per person per day.
