Filtration Testing and Slurry Conditioning

By Chemical Engineering |

Testing in filtration processes is critical for determining the properties of solids being filtered and the ease or difficulty of the filtration. In addition, laboratory testing is important in specifying filter media, filter aids, filter area, cake space needed and cake discharge techniques. Experimental data gathered in the laboratory help in the design of the full filtration system needed for production. In many cases, the optimal filtration system involves combining various filtration techniques with different configurations. The mechanical conditioning of slurries allowed by combining filtration techniques gives rise to a more efficient overall filtration process. This article discusses what data are required for slurry testing and provides examples of mechanical conditioning of slurries using combinations of filtration methods. Test objectives Laboratory testing often uses a test sample of process fluid in a container that allows measurement of the volume of the test batch for filtration. Tests are designed to analyze cake depths, operating pressures, filter media, washing and drying efficiencies and cake discharge. An example of a data collection sheet for filtration laboratory testing is shown in Table 1. The specific objectives…
