As a wastewater treatment plant operator, we measure BOD in the inlet and outlet water stream on a daily basis. This information is used to estimate the wastewater treatment efficiency. Unfortunately, the five day incubation period makes it impossible to do any technological correction if something went wrong. Measuring the BOD in real time means we’ll be able to fine tune the operations and keep the outlet stream in optimal parameters. The local water ecosystems will be kept safe and they’ll provide important ecosystems services such as fresh water, oxygen production and climate regulation.
