The Wastewater Whiteboard: BOD vs COD (Biochemical Oxygen Demand vs Chemical Oxygen Demand)

Welcome! I am a CA Grade 4 Wastewater Treatment Plant Operator and Chief Plant Operator. I also hold a CA D3 Drinking Water Distribution Operator Certificate and a CA T2 Drinking Water Treatment Plant Operator Certificate. This is the first in a new series called The Wastewater Whiteboard, which distills concepts down into easy-to-understand discussions. Today we discuss BOD (Biochemical Oxygen Demand) vs COD (Chemical Oxygen Demand) and how they relate to each other. We go over their definitions, uses, what constituents they cover, and laboratory procedures. This info is relevant to all grades and all levels of test takers out there, and will most benefit entry level exam takers like the Grade I, Grade II, and Class C. Like, subscribe, and comment any questions. Enjoy!
