Abstract: An integrated process that includes liquid-solids separation and filtration system that treats swine or dairy feeding operations residual waste (manure flushwaters) for recovery of solid and dissolved nutrients for reuse and recycling of water from these wastes for a variety of uses. The system includes a coarse liquid/solids system to remove coarse material and multi stage, multimedia filter system that includes a set of modules. Each module includes screen assemblies and filter media sandwiched between the screen assemblies. A plurality of control assemblies is associated with each of the modules. The control assemblies include at least one external valve and are in fluid communication with a corresponding module to control flow through the corresponding module.

Abstract: A filter system includes a set of modules, each module including screen assemblies and filter media sandwiched between the screen assemblies. A plurality of control assemblies are associated with each of the modules. Each of the control assemblies is in fluid communication with a corresponding module to control flow through the corresponding module. The control assemblies selectively control fluid in each of the modules between at least one of a forward flow through the screen assemblies to treat an influent flow, a bypass flow to bypass at least one of the modules, and a reverse flow to backwash a given filter media. A method of filtering influent includes providing an influent flow to a set of modules, each module including screen assemblies and filter media sandwiched between the screen assemblies. The influent is filtered by directing the influent through the set of modules. A given module is bypassed when the given module becomes occluded.

Abstract: Multi-media modular filtration unit for separating solids from a fluid comprising at least two filtration modules disposed in series alignment within a water tight cabinet, wherein each module has a pressure release valve to allow fluid being filtered to bypass its clogged filtering surface to permit continuation of filtering on an unclogged succeeding surface.
