Bod Experiment Lab Report Discussion

The difference in DO for each sample before and after incubation represents the DO used by the bacteria to decompose the organic matter. Decomposable means that organic matter can serve as food for the bacteria and energy is derived from its oxidation.

Biochemical oxygen demand BOD Bacteria placed in contact with organic material will utilize it as a food source.

. 2 determine the BOD of a domestic greywater sample. Biochemical oxygen demand is a measure of the quantity of oxygen used by. Temperature of water.

The Biochemical Oxygen Demand or BOD is the amount of dissolved oxygen which is used up by these microorganisms and is roughly equivalent to the amount of food organic matter found in the wastewater. Water pollution test the Biochemical Oxygen Demand BOD test. In this experiment we will try to find the temperature that organisms thrive best in on an organism dependent on oxygen and three types of water.

The aim of this lab is to provide you with an opportunity to experience the measurement of a common. Biochemical Oxygen Demand BOD 441. State in a sentence or two whether results from the lab fully keep up with your hypothesis dont support it or support it with some exceptions.

In order to better answer the question of how to make a discussion in lab report consider the following steps when you write your lab report. RESULTS AND DISCUSSION For the second part which is Part B biochemical oxygen demand BOD determination of wastewater the biochemical oxygen demand BOD test measures the ability of naturally occurring microorganisms to digest organic matter in a five day incubation at 20 oC by analyzing the depletion of oxygen. Biochemical Oxygen Demand BOD The amount of oxygen required by the bacteria while stabilizing decomposable organic matter under aerobic conditions.

In addition to preparing diluted samples the experiment utilizes control samples which dictate the strength of the seed. 1 Laboratory Report Experiment 6 Biochemical Oxygen Demand Group 1 Jonathan Damora Tuesday March 11 2014. Proves that the temperature of the water does affect how much dissolved oxygen a body of water can hold.

View BOD_LAB_REPORT_NEWpdf from ENGG 3590 at University of Guelph. The more food that is present in the water the more DO will be used up by the bacteria and the greater the BOD reading will be. In this utilization the organic material will eventually be oxidized to stable end products such as CO2 and water.

Some recommendations to improve the BOD experiment could be to try different nutrient buffer pillows or to use more calibrated equipment to increase the accuracy of. Report BOD azida md zin. The amount of oxygen used in this process is called biochemical.
