Predicting df for BOD and DO in Various Wastewaters
Project Goals
This study aims to establish empirical correlations between the 5-day biochemical oxygen demand and organic decomposition time to control organic pollution in various wastewater effluents. Ultimate biochemical oxygen demand and minimum and average BODt data sets along with their reaction rates were collected from earlier sampling analyses.
Interesting Findings
Results showed that such BOD5 relationships with time (power equations) or with COD (linear correlations) are helpful for wastewater engineers to generate valuable and accurate results for quality control, without the need to conduct laboratory experiments.
Potential Impact
df values can serve as a good start in sampling analysis to reach an optimum cost effective DO5 concentration without the addition of excess
oxygen amounts. Such proposed regression equations would bridge the gap between scientific observations and industrial best practices.
