Even today, the biological oxygen requirements are of fundamental significance in terms of controlling biological waste water treatment plants or the oxygen content in bodies of water.
When determining the biochemical oxygen demand after n days (BODn, n is the incubation time; either 5 or 7), with an expected BOD in the range of 1 mg/l to 6,000 mg/l using the dilution method, in accordance with DIN EN ISO 5815-1 significantly, you considerably reduce personnel output and therefore costs.
