Abstract

Optimization of flocculation-magnetic separation for enhanced phosphorus removal was carried out using response surface methodology (RSM) and Box-Behnken design of the experiment. The effects of mass of ferric salt, mass of magnetic Fe powder and reaction standing time were investigated. 17 tests were performed, and the results showed that the mass of ferric salt and mass of magnetic Fe powder had great effects in the model. The optimum degree of variables achieved in phosphorous removal was pH = 7, mass of ferric salt was 20 mg/L, mass of magnetic Fe powder was 0.6 g/L, and resting time was 5 min. The quadratic model was developed to establish the relationship of the variables to the response. The coefficient of determination (R2) value for the model was 0.9535, which indicated that the experimental results of process optimization were in agreement with the predicted values.
