Iron leaching from bauxite ore in hydrochloric acid using response surface methodology
In this work, hydrochloric acid is used to remove iron impurities in the bauxite ore contained in the diasporite mineral located in the Sari region. The bauxite ore was calcined at different temperatures and times, and then dissolved in a hydrochloric acid solution. After determining the optimum calcination conditions in 1 h at 900 °C, the response surface methodology (RSM) with four factors in...
متن کاملOptimization of ammonia removal in an integrated fix-film activated sludge using response surface methodology
In this work, removal of ammonia from synthetic wastewater using integrated fixed-film activated sludge (IFAS) process was optimized using response surface methodology (RSM). The main operating parameters such as ammonia concentration rate (ALR) and hydraulic retention time (HRT) were optimized to acquire the maximum removal efficiency. The linear, 2FI, quadratic, mean, and cubic models were ut...
متن کاملStatistical Optimization of Conditions for Maximize Production of Mannan by Saccharomyces Cerevisiae Using Response Surface Methodology
In view of the increase in Saccharomyces cerevisiae mannan content, the culture condition for S.cerevisiae were optimized in this study. The influence of culture condition such as original pH, inoculum size, and temperature on mannan production were evaluated using Response surface methodology. The mathematical model was established by the quadratic rotary combination design. with the order of ...

متن کاملEnvironmental Impact of Sewage Sludge Ash Assessed through Leaching
Article history: Received: 22.7.2016. Received in revised form: 2.11.2016. Accepted: 3.11.2016. As part of a wider feasibility study on the possible reuse potential of Croatian sewage sludge ash, ash has been produced by laboratory incineration of sewage sludge from two Croatian wastewater treatment plants. The Croatian sewage sludge ash was tested for soluble heavy metals according to EN 12457...
