Anaerobic / cell molecular bio The purpose of the study is to chronicle and evaluate the effects of different doses of ferric (III) chloride. This experiment is performed to help treat wastes and waste water using bacteria that could ferment it into methane and less toxic products. They used the process called anaerobic digestion, digestion without the presence of oxygen, to fulfill this task. This technology is presumed to have great advantages. However, waste manufacturers who use it are bereaved by its languid process during the period of digestion at a given quantity of waste. Therefore, scientists and authors in this journal, Charles J. Banks and Zhengjian Wang, have conjured a scheme using an ionic salt to enhance the desired yields quickly. Banks and Wang actually used the research and investigations from other two scientists- Anderson and Zhou, as mentioned in the articleto further analyze the ionic salt’s, Iron chloride or ferric chloride, effect in the medium containing the bacteria and waste. The bacterial species are mesophiles, that is, bacteria who grow in moderate temperatures. In the experiment, they are very sensitive to the products it makes such as COD, or known as chemical oxygen demand, and sulphide concentrations. Their sensitivity decreases their rates of digestion gradually. Consequently, scientists are determined to discover an alternative route to eradicate the impediment to the bacteria. They will use different doses of the salt to monitor the effect of the reaction. Four stirred-tanks reactors were used in the study with a volume capacity of 4 liters. They acquired a 4 -liter sample of waste water to utilize for the test. Ferric Chloride was dispensed each day to the reactors. One reactor was used as a control while the other as a variable containing ferric chloride.
