3. U.S. Patent No. 8,101,078 (Issued January 24, 2012)

U.S. Patent No. 8,101,078 claims several methods that involve diverting wastewater from a sewer main and dynamically reintroducing the concentrated solids back into the sewer main. One method dynamically reintroduces the concentrated solids so that wastewater loading is within a preset range. Another method dynamically reintroduces the concentrated solids so that the wastewater loading does not exceed a preset quantity. A third method dynamically reintroduces the concentrated solids so that the solids loading does not exceed a preset range.

4. U.S. Patent No. 8,142,656 (Issued March 27, 2012)

U.S. Patent No. 8,142,656 claims several systems that involve diverting from a sewer main and dynamically reintroducing the concentrated solids back into the sewer main. One system dynamically reintroduces the concentrated solids so that wastewater loading is within a preset range. Another system dynamically reintroduces the concentrated solids so that wastewater loading does not exceed a preset quantity. A third system dynamically reintroduces the concentrated solids so that the solids loading does not exceed a preset quantity.

6. US Patent No. 9,487,425 (Issued November 8, 2016)

U.S. Patent No. 9,487,425 claims both systems and methods for treating sanitary and municipal wastewater that separates the wastewater into at least three streams using a “Richter-type” centrifugal separator.

Heavier-than-water and lighter-than-water solids streams are recombined and fed to a sludge dewatering device without intermediary biological treatment or sedimentation devices and without biological or sedimentation pre-treatment.

8. U.S. Patent No. 9,512,022 (Issued December 6, 2016)

U.S. Patent No. 9,512,022 claims both systems and methods for treating sanitary wastewater (i.e. wastewater from any source that contains biologically active material) that separates the wastewater into at least three streams using any axial flow centrifugal separator. Heavier-than-water and lighter-than-water solids streams are recombined and are fed to a sludge dewatering device without biological treatment or sedimentation devices.

U.S. Patent No. 9,512,022 also claims a system and method for treating sanitary wastewater that separates the wastewater into at least three streams using any axial flow centrifugal separator. Heavier-than-water and lighter-than-water solids streams are recombined and are capable of being fed to directly to the sludge dewatering device.

9. U.S. Patent No. 9,527,014 (Issued December 27, 2016)

U.S. Patent No. 9,527,014 claims a device for separating solids within a water carrier with different specific gravities that includes a hollow discharge tube for discharging a lighter-than-water solids stream. The opening of the hollow discharge tube is slanted and has a concave contour. Without this device, during the wastewater separation process, floating debris can get tangled on the edge of an ordinary discharge tube and clog it.

The unique shape of this discharge tube prevents build-up of hair, fiber, and other floating debris during the wastewater separation process.

10. U.S Patent No. 9,611,162 (Issued April 4, 2017)

The current patent covers both systems and methods for treating sanitary wastewater (i.e. wastewater from any source that contains biologically active material) and separating it into at least three streams using an axial flow centrifugal separator. The liquid streams that include heavier-than-water solids and the lighter-than-water solids are recombined and fed to a sludge dewatering device. This combined stream is capable of feeding the sludge de-watering device without biological treatment systems.

11. U.S Patent No. 10,173,910 (Issued January 9, 2019)

This patent covers 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 Richter-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.

12. U.S Patent No. 11,008,227 (Issued May 18, 2021)

This patent covers the proprietary methods and processes which make Eco’s separation system the most effective and efficient flotation module in the market. It covers the use of a Venturi air injector to add micro air bubbles to the system, a first dose of flocculant to create air entrenched micro floc, the use of a hydrocyclone to further mix the flocculant with the particles after passing a serpentine piping system, a second dose of flocculant is added to the output vortex of the hydrocyclone which vigorously mixes the flocculant with the air entrenched particles making macro floc, and a second addition of micro air bubbles with a second Venturi air injector which adds the bubbles to the exterior of the macro floc. This specially treated macro floc provides rise rates more than twice as fast as any other system on the market. The macro floc treated wastewater then travels through a velocity reduction system to allow for rapid separation which enables a higher flow rate than other systems.
