Removing Excess Nitrogen from the Environment using Denitrifying bioreactors technology as part of Ecological Engineering

September 1, 2012

I know that the Kingdom of Bahrain is after N2 in its different forms. Excess nitrogen from its different sources has been the core of many studies either in the region or continents. Expectations to predict the demand for nitrogen has shown a jump from 9.5 Million liters per anum in the industrial uses in 1988 to reach 33 Million liters per anum in the industrial sectors in 2011. The same consumptions for oil field suppose to jump from 0.55 Million liters per anum in the petroleum sectors in 1988 to reach 3.5 Million liters per anum in 2012. There is others demand in the form of medical to be 0.45 (1988) to reach 6.5 (2012) as Million liters per anum The figure is for the HVAC system and cooling sectors plus others started in 1988 as 0.25 million liters per year to reach 11.5 Million liters per year. So I put it as a total in 1988 to be 11.5 Million liters per year to jump 35 Million liters per year in 2012. The nitrogen is important to agricultural and urban lands are contaminating groundwater, streams, lakes and estuaries, where it causes harmful algal blooms and contributes to fish kills. The Cost-effective approaches to removing this nitrogen from croplands and urban stormwater runoff before it reaches sensitive water bodies have been elusive. Now researchers are experimenting ideas to do denitrification that brought together ecologists, engineers and policy experts to find answers. This is a beautiful idea to fulfill the needs of the society at the cheapest way. Denitrification is a biological process carried out by soil and aquatic microorganisms, in which forms of reactive nitrogen are converted to unreactive and harmless dinitrogen gas. This is in its way an opening idea for chemical engineering departments in the region to start-up experimental approaches to produce the nitrogen. I tried to find out some information’s on how to produce nitrogen for the benefit of GCC countries and did some work on extracting nitrogen from carbon generator but found problems with reactors design. This special issue of Ecological Engineering, as a part of sustainability ideas could be started when mingling biological dept with chemical engineering dept to produce what is requires. There is a nitrogen producing pilot plant in college of science but this has nothing to do with the sustainability idea of ecological engineering. Ecological engineering is a subject that should exploit both skill and science and engineering background. If its focus on managing denitrification in human-dominated landscapes, highlights our need to understand Earth’s microorganisms and their processes. I call for a need of a workshop to identify the need for nitrification engineering using international and interdisciplinary group of scientists and engineers to synthesize the knowledge necessary to provide pure water for generations to come. The expertise skill needs to address the goal of using ecological principles in engineering design to control nitrogen pollution. The goal is to evaluate a new and relatively inexpensive way to treat wastewater and drainage from agricultural lands using “denitrifying bioreactors.” These bioreactors use common waste products, such as wood chips, to provide a food source for naturally occurring microorganisms. The microbes convert dissolved nitrogen into harmless nitrogen gas, which is then released to the atmosphere. All confirm that denitrifying bioreactors may be used in many settings, and operate well in a range of temperatures. Research in this issue of should start by using and facilitating the Ecological Engineering goes a long way toward applying a scientific understanding of the biological processes of denitrification to the engineering challenges of denitrifying bioreactors.
