Sewage population equivalent
WebAn activated sludge system is designed to treat wastewater from a population equivalent of 65,000 . The domestic wastewater contains 220 mg / L of organic compounds and need to be reduced to 20 mg / L. Volume of the reactor used is 3800 m 3 and the biomass concentration in the reactor is maintained at 3000 mg / L. http://www.abccert.org/pdf_docs/abcwwtfctable.pdf

WebPopulation equivalent refers to the amount of oxygen-demanding substances (measured in BOD or BOD5) in wastewaters whose oxygen consumption during biodegradation equals the average oxygen demand of the wastewater produced by one person during one day. For practical calculations, it is assumed that one unit equals 54 grams of BOD per 24 hours. WebPopulation Equivalent - Population Equivalent is the total strength of wastewater for estimating the treatment required for municipal sewage treatment plant.
