In this study, accumulated data of Up-flow Anaerobic Sludge Blanket (UASB) reactor treating petroleum refinery wastewater under six different volumetric organic loads (0.58, 1.21, 0.89, 2.34, 1.47 and 4.14 kg COD/m3�d, respectively) were used for developing mathematical model that could simulate the process pattern. The data consist of 160 entries and were gathered over approximately 180 days from two UASB reactors that were continuously operating in parallel. Artificial neural network software was used to model the reactor behavior during different loads applied. Two transfer functions were compared and different number of neurons was tested to find the optimum model that predicts the reactor pattern. The tangent sigmoid transfer function (tansig) at hidden layer and a linear transfer function (purelin) at output layer with 12 neurons were selected as the optimum best model. © Maxwell Scientific Organization, 2013. date: 2013 publisher: Maxwell Science Publications official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84880662666&doi=10.19026%2frjaset.6.3827&partnerID=40&md5=15763de3334b093c96846acb77d8d5d2 id_number: 10.19026/rjaset.6.3827 full_text_status: none publication: Research Journal of Applied Sciences, Engineering and Technology volume: 6 number: 11 pagerange: 2077-2082 refereed: TRUE issn: 20407459 citation: Gasim, H.A. and Kutty, S.R.M. and Isa, M.H. and Alemu, L.T.
