Energy Intake Models for Intermittent Operation of Dead-End Microfiltration Filling Line

In filling lines equipped with membrane separation devices in the form of filters energy, consumption is only one important working parameters, other being sustainable filter performance terms efficiency. As line typically a valve, intermittent operation an its use. Whereas overall energy filtration process governed by continuous mode, characterised opening/closing contributes most to problems failure, i.e., breakthrough filtered particles through membrane. A model for determination intake microfiltration during opening and closing valve presented this work. The based on computational analysis pressure wave signals recorded using Fourier transform, expressed nondimensional area specific form. applied case constant dead-end three types: single filter, stacked pleated surface areas ranging from 17.7 cm2 2000 cm2. Both clean filters, as well partially clogged cases are taken into account. Second order polynomial models developed evaluated extensive experimental data. results show that largest was observed case. When fouling occurs at flow rate values it leads larger intake, however, due decreasing these do not exceed
