    Abstract: A rotary drum-type vacuum filter in which the grids which support the flexible filter medium over the filtering compartments of the drum are respectively formed to provide one or more corrugations extending generally in the direction of the drum axis and defining one or more channels, said corrugations also defining valleys in addition to said channels and into which the flexible filter medium is sucked during its immersion in the slurry being filtered to form corrugations in the filter media which mate with said valleys. Thereafter, when the filter medium emerges from the slurry with a filter cake formed thereon said mating corrugations, the channels are eliminated by removal of the filter medium from the drum for passage on to the discharge roll. Such elimination of the mating corrugations from the flexible filter medium and the resulting elongation of the filter medium relative to the less flexible filter cake, facilitates the separation of the cake from the medium.

    Abstract translation: 一种旋转鼓型真空过滤器，其中分别形成在滚筒的过滤隔室上支撑柔性过滤介质的网格，以提供大致沿鼓轴方向延伸并限定一个或多个通道的一个或多个波纹，所述波纹 除了所述通道之外，波纹还限定了谷，并且柔性过滤介质在其浸入被过滤的浆料中时被吸入其中，以在与所述谷配合的过滤介质中形成波纹。 此后，当过滤介质从其上形成有滤饼的浆料中排出时，通过从滚筒上除去过滤介质以通过排出辊而消除通道。 从柔性过滤介质中消除配合波纹和相对于较不柔性的滤饼导致的过滤介质的延伸，有助于将滤饼与介质分离。

    Abstract: Sewage is subjected in sequence to primary and secondary treatment to derive separately therefrom a primary sludge formed of heavier solids and a secondary sludge formed of relatively lighter solids. The primary sludge is concentrated by filtering to form a comparatively dry filter cake, and the secondary sludge is delivered into a flotation tank, together with a pressurized solution of air and water, so that air bubbles released incident to the reduction of pressure attach to the agglomerated sludge particles and float them to the surface of the body of liquid within the tank. The floating blanket of sludge is removed from the tank and blended with the filter cake to form a substantially homogeneous liquid slurry which is then spray-dried and incinerated.
