Biochemical oxygen demand from customers is the amount of oxygen eaten by micro organism and other microorganisms whilst they decompose organic subject underneath aerobic situations.
Dilution Aspect: Dilution Aspect will be the ratio of the amount from the sample to the quantity on the diluted sample. It's employed during the formula of BOD if the sample is diluted for its volume reduction. Quantity of Sample is the quantity of your undiluted h2o sample measured in millilitres (mL).
น้ำเสียมาจากโรงงานอุตสาหกรรม : และกิจกรรมมนุษย์อื่น ๆ มีปริมาณสารอินทรีย์ที่สูง เช่น น้ำหลังจากกระบวนการผลิตอาหาร น้ำเสียจากการเคลื่อนไหวของยานพาหนะ และน้ำเสียจากการบำบัดน้ำมัน ซึ่งประกอบไปด้วยปริมาณมากของไขมัน โปรตีน และสารอื่น ๆ ที่สามารถย่อยสลายโดยจุลินทรีย์ได้
If there is not any food items supply, there is often no BOD, because there click here would be no oxygen demanded for breakdown of the food. The reasonable issue to inquire is: Imagine if your effluent is extremely-clean; it's no meals supply for that bugs?
