    • A continuous microfiltration machine for removing suspended solid particles from process and waste water comprises a container (2) with an inlet conduit (4) defining a flow direction (F), and having therein an influent chamber (7) for feeding the liquid to be filtered, a treatment chamber (8) with a bottom wall (9), at least one pair of filter disks (1 0) keyed to a shaft (1 2) perpendicular to the flow direction (F) and having inner filter surfaces (1 0') outer surfaces (1 0") and outer peripheral edges (1 5) in sliding contact with the bottom wall (9), an effluent chamber (1 7) for receiving the filtered liquid, with a discharge conduit (1 8), drive means (1 3, 14) for imparting rotation to the disks, first jet washing means (20) directed against the outer surfaces (1 0") of the disks (1 0) for removing the particles retained thereby, a first collecting duct (24) for collecting the removed particles, which is interposed between the disks (1 0) and has substantially parallel side edges (25) located at a predetermined minimum distance (D) from the inner surfaces (1 0') of the disks (1 0). The inner surfaces (1 0') of the disks are substantially flat and continuous surfaces, with a flatness error (ε) smaller than said predetermined minimum distance (D).
    • 用于从工艺和废水中除去悬浮固体颗粒的连续微量过滤机包括具有限定流动方向(F)的入口管道(4)的容器(2),并且其中具有用于将液体供给的流入室(7) 过滤,具有底壁(9)的处理室(8),至少一对键合到垂直于流动方向(F)的轴(12)的过滤盘(110),并且具有内部过滤器表面(1) 0')和与底壁(9)滑动接触的外周边缘(15),用于接收过滤液体的流出室(117)和排出管道(108) 驱动装置(13,14),用于使盘旋转;第一喷射洗涤装置(20),其指向盘(10)的外表面(10),用于除去由其保留的颗粒;第一收集 导管(24),其用于收集被移除的颗粒,其被插入在盘(10)之间并且具有基本平行的侧边缘 s(25)位于与盘(10)的内表面(10')预定的最小距离(D)处。 盘的内表面(10')基本上是平坦且连续的表面,平坦度误差(ε)小于所述预定最小距离(D)。
