## Research of suspensions filtration in a filter press

### Piotr Gajewski

#### Abstract

The process of the filtration in the filter press involves separating particles present in suspended solid matter from a liquid. The result of the process is the separation of the filter cake and filtrate. The aim of the research was conducting the filtration process of chalk in the filter press. The research was performed in a constant pressure and stable filtration speed. The range of the research included: preparing the equipment, making suspension, performing the filtration and washing the filter cake. The second part of the research included preparing educational materials in the form of the multimedia presentation. The filter press used in the research had five pairs of board-frame sets of the total area of the filtration S=0.305m2. The suspension of water and chalk of 1%wt. with addition of salt NaCl of 0.5%wt. concentration was filtered. The experimental part included the performance of the filtration under the constant pressure. During the practical part of the research it was stated that the filtrate was clear and the cake had a compact structure. On the basis of the research the following charts were elaborated: the volume of the filtrate in the function of time, the inverse of the filtration speed in the function of volume the filtrate and the conduction of the washings in the function of the washing time. Moreover, constant filtration values were fixed as well as the compressibility coefficient of the filter cake. Besides, the volume of the washing liquid needed to wash the filter cake was fixed too. All the findings are presented in the forms of the tables and charts.
