This Evaluation is performed using three hundred mL incubation bottles where buffered dilution drinking water is dosed with seed microorganisms and stored for five days at midnight area at 20 °C to stop DO production by using photosynthesis. The bottles have historically been made of glass, which required cleansing and rinsing amongst samples. A SM 5210B accredited, disposable, plastic BOD bottle is offered which eliminates this move. Besides the assorted dilutions of BOD samples, this procedure requires read more dilution drinking water blanks, glucose glutamic acid (GGA) controls, and seed controls.
