As being the title implies, a DO test steps the focus of oxygen dissolved inside of a drinking water or wastewater sample.
The seed (bacteria) added to every Answer will degrade the biodegradable substance in each sample relative to the quantity of oxygen removed from the water. click here The sample dilution and number of oxygen removed can be utilized to compute the quantity of biodegradable material inside the sample in mg/L. Every single sample will have to create a residual of 1.0 mg/L of dissolved oxygen and have had click here a dissolved oxygen uptake of a minimum of 2.0 mg/L.
In case the BOD is 300mg/L and previously mentioned, sewage is said to become weak, and whether it is 100mg/L or down below, it is claimed for being wholesome.
