    • A filter and housing (10) for waste water treatment includes a housing (10) having a plurality of coaxially mounted vertically extending sections adaptable to receive a filter cartridge therein. An upper section (12) is provided with an outlet consisting of at least two coaxially aligned rings (22) of preselected diameters wherein the thickness of the rings and the spacing between the rings is sufficient to receive waste water treatment outlets of different diameters. The filter cartridge is comprised of a stacked arrangement of a plurality of disc-dam units (32) wherein each disc-dam unit (32) is provided with a serpentine configured first dam (46), the first dam extending upwardly from an upper surface of the disc-dam unit, the first dam having terminating ends spaced at outer terminating edges (34a, 34b) of the disc dam unit to define a cord segment therebetween. The terminating ends are connected by a second dam (46) having a height less than the first dam. The serpentine configured first dam divides the disc-dam unit into an upstream side along the outer periphery and a downstream side along the inner periphery. Slots are positioned within the serpentine configured dam on the upstream side thereby providing flow communication with underlying disc-dam units. The top of the first dam is of a preselected height so as to provide a preselected spacing between the top of the first dam and the under surface of an overlying disc-dam unit.
    • 用于废水处理的过滤器和壳体(10)包括具有多个同轴安装的垂直延伸部分的壳体(10),该部分适于在其中容纳过滤器滤芯。 上部(12)设置有由预定直径的至少两个同轴对准的环(22)组成的出口,其中环的厚度和环之间的间隔足以容纳不同直径的废水处理出口。 过滤筒由多个盘形坝单元(32)的堆叠布置组成,其中每个盘坝单元(32)设置有蛇形构造的第一坝(46),第一坝从上表面向上延伸 所述第一坝具有在所述盘坝单元的外终止边缘(34a,34b)处间隔开的端部端部,以在其间限定绳索段。 终端通过具有小于第一坝的高度的第二坝(46)连接。 蛇形结构的第一坝将圆盘坝单元沿着外周边和沿着内周的下游侧分隔成上游侧。 槽位于上游侧的蛇形构造的坝内,从而提供与下面的盘坝单元的流动连通。 第一坝的顶部是预选高度,以便在第一坝的顶部和上覆的盘坝单元的下表面之间提供预选的间隔。
