Biodegradation of Hazardous Waste during Biological Treatment Process

In recent years, biodegradation and its application in bioremediation of pesticides has proven to be an appropriate method for treatment of polluted aquifers that could be implemented either in-situ or off-site in especially designed reactors or wastewater treatment plant. In practice, activated sludge process has been found very effective in the treatment of organic compounds. However, in order to treat toxic substances in such system, specific microorganisms are required to be added with controlled operating parameters. This book, therefore, describes a recommended procedure of toxic waste treatment. According to research findings, degradation of Cypermethrin, a least water soluble compound, only be possible in the presence of isolated Pseudomonas organism and its biodegradation rates significantly depend on Cypermethrin concentration as well as operating conditions like temperature, dissolved oxygen, rate of agitation/aeration. Moreover, the mathematical models obtained from the results may also be helpful to scientist and engineers in designing and operating an efficient pollution control treatment system.
