    Abstract: A screen filter for wastewater applications includes a chain tensioner assembly configured to provide a tensioning force for a screen filter chain. The chain tensioner assembly includes a slide plate configured to move axially with respect to the screen filter chain, and a shaft mount attached to the slide plate and configured to mount a shaft. The chain tensioner assembly additionally includes an abutment member attached to the slide plate. The chain tensioner assembly further includes a spring adjuster having at least one spring and configured to contact the abutment member to provide a bias force to the slide plate.

    Abstract translation: 用于废水应用的筛网过滤器包括链式张紧器组件，其构造成为筛网过滤器链提供张紧力。 链条张紧器组件包括被配置为相对于筛网过滤器链轴向移动的滑动板和附接到滑动板并构造成安装轴的轴安装件。 链条张紧器组件还包括附接到滑动板的抵接构件。 链条张紧器组件还包括弹簧调节器，弹簧调节器具有至少一个弹簧并构造成接触抵靠构件以向滑板提供偏置力。

    Abstract: In one embodiment, a system includes first anoxic moving bed biofilm reactor (MBBR) configured to receive a fluid containing selenium and to process the fluid via a first biofilm disposed on a first media to produce a first MBBR fluid by removing nitrogen from the fluid. The system further includes a second anoxic MBBR fluidly coupled to the first MBBR to receive the first MBBR fluid and to process the first MBBR fluid via a second biofilm disposed on a second media to produce a selenium enriched fluid, followed by a solid-liquid separation system to remove selenium in solid form as sludge and produce a treated effluent containing equal to or less than 5 micrograms of selenium per liter. The system includes a plurality of first sensors and first actuators disposed on the first MBBR, and a plurality of second sensors and second actuators disposed on the second MBBR.
