Abstract
- The biological oxygen demand (BOD) test is widely used in many wastewater treatment plants. The conventional BOD tests are usually time-consuming and the results are often out of date for process control purposes. The aim of this research was to compare the manometric respirometric test with common chemical methods in the determination of BOD of wastewater from a pulp and paper mills as well as to evaluate theBOD7values of both wastewaters from the short-term respirometric measurements. The results showed that there were differences in theBOD7values of paper mill samples measured by conventional and respirometric methods. The main cause was found to be the dilution solution used in the conventional BOD tests. Using the same mineral solution in the respirometric measurements diminished the difference remarkably. Evaluation of theBOD7value after two or three days incubation was proved to work very well and the estimated results were close to measured values (deviations 1%–12%).
