Biochemical Oxygen Demand (BOD)
Biochemical oxygen demand (BOD) is a widely used parameter to assess the organic pollution in water systems. This parameter can be detected by the amount of oxygen consumed via microorganisms in aerobic metabolism of organic matter present in the water. The authorized test to analyze biodegradable organic compounds is given by the American Public Health Association Standard Method Committee tha...
متن کاملMethods for assessing biochemical oxygen demand (BOD): a review.
The Biochemical Oxygen Demand (BOD) is one of the most widely used criteria for water quality assessment. It provides information about the ready biodegradable fraction of the organic load in water. However, this analytical method is time-consuming (generally 5 days, BOD5), and the results may vary according to the laboratory (20%), primarily due to fluctuations in the microbial diversity of th...
متن کاملimproving the performance of ann model, using wavelet transform and pca methodfor modeling and predict biochemical oxygen demand (bod)
in recent decades, the developments of artificial intelligence to predict hydrologic models have been widely used. in this study, the ability of artificial neural network(ann) models for modeling and predict the biological oxygen demand (bod) is located on the karun river in west iran were evaluated. to improve the simulation results, wavelet analysis was used as a hybrid model. bod index month...
متن کاملthe study and zoning of dissolved oxygen (do) and biochemical oxygen demand (bod) of dez river by gis software
pollution sources into the water, the necessity of qualitative studies of water resources is one of the most important new challenges for mankind in almost every parts of the world. dissolved oxygen (do) and biochemical oxygen demand (bod) are among parameters of water quality indexes which are considered as water pollution indexes. in the present research, do and bod of dez river basin water (...
متن کاملNitrification in the Surface Water of the Włocławek Dam Reservoir. The Process Contribution to Biochemical Oxygen Demand (N-BOD)
Nitrifying activity in the surface water of the Włocławek Dam Reservoir (WDR) was determined by use of a nitrification selective inhibitor (ATU). The highest values of nitrification were observed in the stations nearer the dam, with lower flow velocity, where the activity amounted to up to 120 μg N/dm3/day. Nitrification process [%] involvement in biochemical oxygen demand increased with passin...
