Abstract
Of this research has been thinking of a way to arrange technologies sewage treatment according to specific criteria established by the decision-makers using a mathematical method. Therefore, the goal of the research is to design a matrix using (AHP) Analytic Hierarchy method, to help decision-makers to choose the appropriate technology for wastewater treatment in Egypt according to specific criteria (such as cost - environmental - energy consumption and the number of employment.
Has been compiled data on operational and technical performance of the treatment plants in Egypt, and that showed a discrepancy between the different technologies in terms of cost ,performance , energy consumption and the number of employment... etc. It has been shown that the technology, which consume less energy may need to large areas of the establishment, which can be built on small areas may need to skilled labor for operation. from search AHP method was used to compared between different technologies, with the development of this method is that we can apply in this area by adding new scale called AHPm, Which showed the following: -
In Upper Egypt prefers to use oxidation ponds, extended aeration, activated sludge or primary treatment
In Delta preferred to use primary treatment , extended aeration or activated sludge, and prefers to stay away from technology oxidation ponds, by review of our findings on the nature of the application during the same way on the provinces (Assiut - Menoufia) and comparison, has notes match the order in these provinces with different grades.
Finally, is recommending that the way AHP suitable to be used to compare between the technologies of wastewater treatment according to specific criteria and access to the results can be applied.
Key Words:
Wastewater treatment; ranking of wastewater technologies; Analytical hierarchy process (AHP).
