Introduction
Although a fast growing economic hub, Abu Dhabi remains a relatively dry land that needs maximum water preservation. In addition, the increasing population and number of local, regional and multinational organizations and businesses seeking to operate in the city require adequate supply of water.
At the same time, wastewater management remains a challenge to the city, especially in terms of managing the city’s sewage. However, technology has the potential to recycle much of the wastewater with an aim of preserving the city’s precious water resources while at the same preserving the environment (Tseng & Lin, 2004). The purpose of this paper is to define a wastewater treatment planning for Abu Dhabi’s future.
The plan describes the best technology for wastewater treatment and the process involved. Moreover, it will provide the best possible location as well as the type of operation necessary to enhance wastewater management.
Description of an ideal wastewater management technology for Abu Dhabi
The proposed wastewater treatment plant will be located at Allamahah, some 20 kilometers west of the Abu Dhabi. The purpose is to serve the city’s population both as a source of water and as a water treatment facility. The aim is to treat some 600,000M3/d of sewage per year and produce some 400,000m3/d of clean water per annum for use in the industries and partly for domestic use (Tseng & Lin, 2004).
The plan is to create a conventional treatment plant that will involve a technology to treat the water with efficiency and reliability. The technology will include a preliminary, a primary and a secondary treatment sections. They will include an activated sludge to which a secondary settlement will be developed.
The proposed technology will be primarily a biological model in which there will be minimal use of fuel. The biological section will also be coupled with filtration and a serial disinfection process to ensure that the water is microorganisms-free (McCarty, Bae & Kim, 2011).
In this case, the biological procedure will follow the conventional anaerobic treatment of domestic wastewater (Tseng & Lin, 2004). From a biological analysis, it is evident that anaerobic treatment of wastewater, especially the sewage water, has the potential to enhance energy production while as the same time producing high quality water for domestic and industrial use.
The program has identified a number of issues that need be addressed in order to avoid a case where the production of water will fail. For instance, the problems of low temperature and low organic concentration might be the barrier to the program, as cited in theory.
However, the problem of low temperature is not likely to affect the plant in Abu Dhabi because the area is relatively hot, which makes the survival of microorganism is generally high. Secondly, the plant will involve a high-energy sufficient technique that will oversee the overall preservation of energy (McCarty, Bae & Kim, 2011).
Within the context of biological treatment, the technology will involve genetically engineered bacteria with a high capacity to remove nutrients, organic and inorganic substances as well as kill other microorganisms. It is also expected to include a number of bacteria species with different capacities to ensure that all these substances are removed from the water.
It is also important to include additional caution because some bacteria may act on others, producing certain effects or rending the process ineffective. For this reason, each species of bacteria used will be positioned in separate chambers, where water will pass through to ensure the full effect of the bacteria on the water.
