dc.description.abstractThere is a growing use of nonwovens in technical applications such as filtration. The ability to understand the parameters that influence the filter medium is important for the use of filter media. Parameters like pressure drop and efficiency are the two most important parameters that filter media designers consider when designing filter media. The aim of this study is to test if the geometry of pleated filters produced by the ROTIS II technology has influence on the following filtering parameters: pore size, pressure drop and filtration efficiency. This will also involve comparing these parameters to find if there is linear relationship between them. For this study pleated filter media was prepared using the ROTIS II technology and tested. Their results were compared to that of flat filter media to find out if the is an influence on filtering parameters. The permeability coefficient results have shown that pleating the filter media increases its permeability coefficient than flat filter media. However if were to use the same weight of material for flat filter as in pleated filter media we will increase permeability coefficient slightly higher than that of double layered filter media. Pleating the filter media changes the pore sizes. Pores can be smaller or larger than that of flat filter media depending on the pressure. There is no linear relationship between pore size and permeability coefficient. There are varied results for pore size against dust starting pressure as such we could not come to the conclusion that there is linear relationship between pore size against dust starting pressure. Pleating the filter media increases the efficiency of the filter media that do not have 100 percentage efficiency. The pore size influences the efficiency of the filter media. The smaller the pore size the higher is the efficiency and the larger the pore size the smaller is the efficiency however this linear relationship does not apply to filter media that have 100 percentage.cs
