Multilayer technical fabrics are an important part of fibrous filters used in raw water filtration systems. The implementation of the filtration process depends on the structure of the fabric system, water particle deposition mechanisms and water flow conditions. This paper discusses, in terms of theoretical models, the results of an investigation on the flow resistance and efficiency of raw water filtration at the initial stage, in which the dispersed phase consists of liquid particles, through a multilayer technical fabric system with different structural parameters.
The research results indicate the functional dependence of filtering properties on thestructural parameters of the fibres studied (primarily, fabric packing density coefficient,fabric tightness, and raw water flow parameters, such as the water flow rate (time)). The results of the research on multilayer technical fabrics with particular focus on the analysis of pore fraction distribution may be of crucial importance in forecasting the use of multilayer technical fabrics as filtering media for raw water filtration processing, considering that the conditions are sufficient
