Owing to deposition of solid particles in the used in filters, considerable losses can occur with able solids throughput. This negative effect is intensified if the fluid phase; generally water; contains salts that can crystallise. Investigations on pressure disc filters of Ruhrkohle AG have revealed that a comprehensive cleaning of filter mesh is not possible with the standard cleaning equipment (high pressure water jet with pressure difference 25 bar) installed at the filters. Pressure differences of 170 bar and more are required for this. On the basis of the test results, a high pressure water jet cleaning unit was developed as prototype on two filter plants. In both cases, a considerable increase of throughput rate and also a slight improvement of content of filter cake was able to be achieved with Currently a cleaning unit is being developed at DMT-Gesellschaft fur Forsching und Prufung mbH where the A the prototype unit (e.g. high weight) have been eh~ ly, this can be applied to all known and industrial1y used disc filer types.
