ZP is an ISO13485 independent contract developer and manufacturer of biosensors including dissolved oxygen (DO) sensors, which can have application in Biochemical Oxygen Demand (BOD)
BOD
Biochemical Oxygen Demand (BOD) is a measure of the amount of dissolved oxygen that microorganisms consume while decomposing organic matter in water. It is a key parameter used to evaluate the quality of water in streams, lakes, and wastewater treatment plants. BOD is expressed as the amount of oxygen in milligrams per liter (mg/L) required for the decomposition of organic matter under specific conditions, usually over a five-day period.
The BOD test is typically conducted by measuring the dissolved oxygen (DO) content of a water sample at the beginning of the five-day incubation period and again at the end of the incubation period. The difference between the initial and final DO concentrations is then used to calculate the BOD value. The higher the BOD value, the greater the amount of organic matter present in the water, and the lower the water quality.
BOD is an important parameter used in the design and operation of wastewater treatment plants to ensure that the discharge meets regulatory requirements and does not cause harm to the environment. BOD can also be used to monitor the health of aquatic ecosystems by measuring the oxygen demand of microorganisms in the water.
