Summary of results and process implications

With the a-form of particle, the required filter area is 2 m for the specified 50 kg of solids per batch and 50 mm cake thickness. Each cake discharged 

Total volume of liquids produced during cycle (m ) 0.773 0.736 

The implications of processing the -form of particle are significant in terms of either longer cycle times and/or raised equipment specification. 

The calculations presented in Sections 6.4.1 and 6.4.2 illustrate the degree to which the operation of a filter can be predicted from the knowledge of suspension and cake properties as well as basic operational parameters. Simulations develop these procedures to allow the performance of batch filters to be investigated over a wide range of process conditions without the need to perform costly sequences of experiments. While any of the filters shown in Table 6.1 can be simulated with the aid of the equations and procedures presented throughout this chapter, the diaphragm filter press cycle considered in Section 6.4.1 is chosen to illustrate the process.
