A method for separating swine waste using at least one perforated conveyor belt and at least one fluid trough. A quantity of swine waste is collected through a slatted floor of a barn into at least one funneling channel. The quantity of swine waste is gravity-fed through the at least one funneling channel onto at least one perforated conveyor belt. Liquid waste is strained from the quantity of swine waste on at least one perforated conveyor belt into the fluid trough, retaining solid waste on the at least one perforated conveyor belt. The solid waste is then transported into a solid-waste storage vessel with the at least one perforated conveyor belt. Simultaneously, the liquid waste is gravity fed into a liquid-waste containment vessel from the at least one fluid trough. The solid waste and the liquid waste are stored to be processed later.

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.

The disclosed technology regards a water/solids separator for filtering slurry into residue cakes and filtrate water. The separator includes a frame supporting a plurality of rollers supporting a filter media belt, a plurality of blades and wipers for cleaning the rollers and removing excess filtrate water and cake material, and an inlet water manifold to distribute slurry water uniformly on the filter media belt. The frame supports a filter bed, with a slurry receiving area having a perforated panel at its base, for receiving, pre-filtering and moving the slurry through the separator, and a filter bed collection tub with an exit aperture for collecting and delivering filtrate to a water holding tank. The filter media belt traverses the plurality of rollers, through and about the filter bed, supported along a portion of its path by the perforated panel. Both a residue cake bin and a clean water holding tank may be provided with the system to collect residue and filtrate water, respectively, for re-use or disposal. The present invention also regards a method for separating filtrate water and cake residue from slurry, using the water/solids separator herein described, by continuously providing slurry through the inlet water manifold, while powering the gear motor to cause rotation of the drive roll, resulting in rotation of the filter media about the plurality of rollers. By this method and the disclosed technology, a portion of the water from the slurry is removed, through the filter media belt and the perforated panel.
