<p>There is described a control system for a filtration assembly wherein the amount of medium introduced into the filtration assembly is constant, even though the filterability of the medium or the condition of the filters has changed, in that the working cycle of the filtration assembly changes when the pressure difference across the filter mesh increases over a certain period of time, said control system being capable of distinguishing between the filterability of the medium introduced and the condition of the filter mesh.</p> |
