Oil is an essential component used in various industries and it is therefore controversial in many countries. Eversince its discovery and traortation by sea marine, ecosystems were put at serious risk. There is a wide range of methods to prevent and control oil pollution, and yet none of them is flawless. Applying technical textiles such as fibrous substrates is one common method to separate oil from water, as it is simple and effiecient. In this study, a new structure is designed that recycles and collects oil from a mixture of water and oil, using technical textiles. Four types of commercial technical textiles have been used for various experiments. Independent variables in these experiments include fabric type (nonwoven and spacer weft-knitted), thickness and density of the fabric, number of layers of fabric used in the sample (5, 7 and 9 layers), dimensions of the fabric, inlet flow rate, and presence or absence of the drains. The employment of drainage in the structure of the filtering device was an important innovation in this research. An absorption capacity test was conducted on filtering devices. Experiments were designed according to Taguchi method and analyzed in Minitab v17.1.0-F4C software. The filtration structure which had a drain system consisting five filtering layers with a thickness of 0.378 mm showed a better oil absorption than other filtered samples. A numerical model was also fitted to predict the output concentration of the filter based on time and mass balance for complete mix reactors. The adaptation of this model to laboratory results was investigated. The experimental results showed a good correlation with the outputs of the proposed model
