Web6 Sep 2024 · So, the more the organic content in the water the higher is the value of BOD. The value of BOD is expressed in milligrams of oxygen per litre of a given sample. The BOD is considered weak in the given water sample when the value is around 100 mg/l; medium when it is 200 mg/l and strong at 400 mg/l. Web7 Apr 2024 · As a result, the five-day Biochemical Oxygen Demand (BOD 5) test was invented in 1908 as a measure of organic pollution in water. BOD 5 is one of the most frequently used sum parameters for establishing levels of organic contamination in wastewater.
WebOur company designed and built an air release valve specifically for wastewater mains that actually works.
