FILTRATE SPLASH PLATE AND/OR DEFLECTOR | 2 |
| 20080203006 | Self-standing weighted diffuser assembly - An apparatus designed to convert the dynamic of residential wastewater treatment processing bacteria from anaerobic to aerobic bacteria in existing single or multiple compartment septic tanks. The apparatus consists of a small self-standing weighted diffuser assembly designed with a center tube having a specific series of vertically lined orifices and a deflector plate that can be lowered through an 8-inch diameter opening by means of the attached flexible airline into an existing septic tank and sit directly on the bottom of the septic tank. A flexible airline attaches the diffuser assembly to a small air pump located outside of the septic tank. When the air pump is activated, air will enter the diffuser assembly and discharge through the orifices a combination of fine and coarse air bubbles. This action causes the wastewater to be forced against the deflector plate and creates a rolling action starting at the bottom of the septic tank and rolling upwards toward the outside of the tank. This rolling wastewater is forced to the top of the liquid level in the septic tank and then is pulled back down to the bottom and back toward the diffuser where the cycle begins again. This unique action takes place on all sides of the diffuser assembly very quickly breaking solids down into small particles. Additional benefits include the production of sufficient oxygen in the wastewater to proliferate the growth of aerobic bacteria. With the constant rolling action of sewage and particles, it is necessary especially in a single compartment septic tank to eliminate those particles from exiting the tank and entering into the secondary treatment system. The apparatus is designed to draw those small waste particles down and away from the septic tank discharge point, and back toward the diffuser assembly ensuring those particles do not exit the septic tank. | 08-28-2008 |
| 20090145832 | Pipe separator - A pipe separator for separation of a fluid, in particular separation of fluids with non-mixable fluid components such as oil, gas and water, comprising an extended tubular separator body with a diameter that is principally the same as or slightly larger than the diameter of the inlet pipe and the outlet pipe(s) for the separated components from the separator. | 06-11-2009 |
