The wastewater reuse was investigated the efficiency of fecal coliform(FC) removal using the intermittent media infiltration (IMI) with varying soil content and natural porousmedia (sand, zeolite, vermicompost and charcoal), and its prediction was introduced by applying fuzzy rulesemulated network (FREN). The physicochemical properties of the porous media were determined and themechanisms of FC removal were discussed as the effect of fine particle size and increasing of ion charges. The compositions of soil and porous media at a ratio of 75/25, respectively, gave the best performance of FC reduction. The network architecture was constructed by the knowledge regarding to the relation between soil content (25, 50 and 75) and FC removal, and was introduced IF-THEN rules for FREN construction as theirpredicted curves at 20 iterations. The learning rate was selected as 5 following the main theorem and theconvergence of FREN prediction could be guaranteed. The results showed that the prediction methodologygave a good performance to forecast FC removal with the range of soil content (20-80%) and several compositions of porous media in IMI system.}, keywords = {Bacterial removal,fuzzy logic,infiltration,Porous media,Prediction}, url = {https://ijer.ut.ac.ir/article_623.html}, eprint = {https://ijer.ut.ac.ir/article_623_80ccc13d7cb050a82a4b440a8f8cd1d2.pdf} }
