Abstract: Disclosed is a system and method for treating municipal and sanitary wastewater. The system includes a three-output axial-flow type separator that separates wastewater into at least three fluid streams according to the specific gravity of the solids within the fluid streams. The lighter-than-water and heavier-than-water solids streams are combined and the resultant combination capable of being mechanically dewatered without intermediary biological-process systems. The system advantageously simplifies municipal and sanitary wastewater treatment by potentially eliminating traditional primary and secondary treatment stages, and significantly reducing the system's operational footprint. The system and method can be scaled to very large municipal systems.

Abstract: Disclosed is an apparatus for separating solids within a water carrier having different specific gravities. The apparatus includes an axial-flow pump with an impeller (13). The apparatus includes a hollow tube (11) sized and positioned to discharge a fluid stream where the solids within the fluid stream have a specific gravity less than one. The hollow tube (11) includes an inward facing opening that makes an oblique angle along its entire circumference with respect to a longitudinal axis of the hollow tube (11). This arrangement is especially useful in municipal and sanitary wastewater treatment applications for keeping lighter-than-water debris such as hair, food fiber, and synthetic fibrous materials from building up against the leading edge of the hollow tube (11) and clogging it.

Abstract: Disclosed is a system and method for treating municipal and sanitary wastewater that uses only mechanical devices and processes, which eliminates biological processes and settling tanks. The system includes a three-output axial-flow type separator that separates wastewater into three fluid streams according to the specific gravity of the solids within the fluid streams. The lighter-than-water and heavier-than-water solids streams are combined and the resultant sludge is mechanically dewatered without intermediary biological-process systems or sedimentation. The partially clarified water component can be directly filtered by a membrane filter and optionally optically or chemically disinfected for reuse or disposal. The system advantageously simplifies municipal and sanitary wastewater treatment eliminating traditional primary and secondary treatment stages, and significantly reducing the system's operational footprint. The system and method can be scaled to very large municipal systems.
