Modernisation of filter design with bulk dispersed media

Abstract

The object of research in this article is the design of the filter with bulk dispersed media; this type of device has a wide application within the framework of water treatment for technological needs of food enterprises. On the basis of the data of the previously obtained complex of theoretical and experimental studies of the process of bulk filtration of mechanically activated aqueous solutions, the main purpose of the work is to find effective options for modernisation of the filter design with bulk dispersed media, allowing one to improve the filtration process, namely to increase productivity and improve the quality of filtrate. The research methods included both theoretical (methods of analysis, comparison, etc.) and experimental measures aimed at studying vibromechanical activation of the initial solution in the process of filtration, studying the physical and chemical properties of the activated solution, and determining the rational modes of mechanical action. The results obtained in the course of the research are determined by the basis of the modernisation of the device, the changes made in the design had a positive effect on its operation, and the cycle time changed by 20-22 %. The achievements of the device modernisation are represented by: built-in vibromechanoactivators; washing and regeneration without the use of reagents; measurement by sensors of indicators in the device tanks before and after the filtering process; improved wear resistance and durability of the casing coating inside and outside. On this basis, further plans are focused on the realisation of the design ideas into an experimental industrial unit and subsequent research in laboratory and industrial conditions.
