An apparatus includes a materials separator that includes a continuous filter belt disposed around a plurality of rollers. The apparatus also includes a pressure differential system operatively coupled to the separator and configured to adjust a pressure differential across the continuous filter belt. A vacuum is applied to the continuous filter belt and a fluid portion of the slurry on the continuous filter belt is drawn through the continuous filter belt. An apparatus includes a materials separator having a first deck with a first continuous filter belt and a second deck with a second continuous filter belt.

The invention relates to a conveyor belt filter device for mechanically cleaning a liquid which flows through a channel and is polluted with solids, comprising an endless filter belt of interconnected flat filter elements which can be pivoted against one another, and a flexible driving means which is guided over a lower deflection device and at least one upper deflection device and comprising a framework which carries the deflection devices and the filter belt, wherein in the area of the upper deflection device a wiper device is arranged which can be driven to rotate and is arranged on a swinging link which is mounted on the framework, the wiper device being supported against the weight of the wiper device by a support device, and the support device being arranged together with the upper deflection device on a common carrier which is adjustable with respect to the framework.

A system and process for removing from an aqueous stream impurities such as grit, particulates, floating debris, suspended solids, turbidity, bacteria, fecal coliform, oil, grease, color, and the like, and for treating an unacceptable biological oxygen demand, chemical oxygen demand, and/or dissolved oxygen by utilizing a treatment system positioned partially in a channel adapted to a flow of the aqueous stream. The treatment system comprises a containment zone for containing the aqueous stream for treatment by at least one of traveling or stationary screen filtration, aeration, anaerobic and/or aerobic digestion, clarification, media filtration, chemical addition, disinfection, pH adjustment, particulate removal, and/or the like. A partition wall is provided to bypass untreated water such as storm water. After passing untreated waste water through the treatment zone, the treated aqueous stream may be recycled for further use or discharged to its desired destination, such as a lake, river, or ocean.
