Title: Method of Filtering Suspensions
IPC: B01D37/03
Filed: 1979-03-02
Abstract: In the filtration of liquid suspensions, e.g. waste water (@A) containing phosphous impurities to which a flocculant (@F) has been added, using one or more space filters (6) which are subjected to a backwashing process at specific intervals of time, the backwashing process is effected whenever a layer of suspension particles begins to form on the surface of the space filter. The formation of this layer is determined either by a continuous measurement of the pressure drop, e.g. by sensor (7), or by measuring the pressure profile of the filter layer at discrete intervals of time. In the first case, the actual pressure drop is compared in controlled (3) with an ideal pressure drop which would develop without the layer of suspension particles forming at the surface of the space filter. <IMAGE>
