Techno-economic analysis of a municipal wastewater treatment plant: A comparison among SBR, MLE & A2O Processes
Sequencing batch reactor (SBR), modified Ludzak Ettinger (MLE), and anaerobic/anoxic/aerobic (A2O), were modeled and simulated using the data of the Konarak-Iran wastewater treatment plant. GPS-X and CapdetWorks software were used for technical and economic evaluation, respectively. The cost of MLE treatment per cubic meter of effluent with a flow rate of 900 cubic meters per day was $ 0.96 per cubic meter, which was 36.4% and 12.5% lower than SBR and A2O, respectively. The removal efficiency of pollutants using the A2O method was above 90%, which has the best efficiency compared to the other two methods. However, since the quality of the effluent is also met by the MLE method, the choice of the same method can be desirable. Therefore, modeling and technical and economic simulation of wastewater treatment to perform comparisons between different methods lead to better engineering decisions based on the cost and quality of effluent.
期刊介绍：
The objectives of Scientia Iranica are two-fold. The first is to provide a forum for the presentation of original works by scientists and engineers from around the world. The second is to open an effective channel to enhance the level of communication between scientists and engineers and the exchange of state-of-the-art research and ideas.
The scope of the journal is broad and multidisciplinary in technical sciences and engineering. It encompasses theoretical and experimental research. Specific areas include but not limited to chemistry, chemical engineering, civil engineering, control and computer engineering, electrical engineering, material, manufacturing and industrial management, mathematics, mechanical engineering, nuclear engineering, petroleum engineering, physics, nanotechnology.
