A wastewater treatment system is provided having a pretreatment tank which receives wastewater from a wastewater source, and an aeration tank which is in fluid communication with the pretreatment tank. A recirculation pump is carried in the aeration tank and returns wastewater from the aeration tank to the pretreatment tank. The recirculation pump returns the wastewater according to a recirculation ratio R:I where R is the volumetric flow rate of wastewater through the recirculation pump and I is average volumetric flow rate of wastewater entering the pretreatment tank. A control panel cycles the recirculation pump on and off according to the recirculation ratio.

Nitrogen-reducing wastewater treatment system

A wastewater treatment system for processing borne wastewater. The treatment system having a tank with an inlet and an outlet and an access assembly residing at the top of the treatment tank. The treatment tank having an aeration chamber where oxygen is added to the wastewater to encourage bacterial breakdown of the solid waste. The treatment tank also having a clarifying chamber separated by a frusto-conical wall. The treatment tank also containing an ultraviolet disinfection system which exposes the wastewater to ultraviolet light prior to the wastewater exiting the treatment tank such that bacteria in the wastewater is neutralized prior to discharge.

A process is disclosed for making new and improved diamond, 'diamond-like carbon' (a-C) and 'diamond-like hydrocarbon' (a-C:H) coatings bonded to substrates by using intermediate bonding layers engineered to reduce the residual stress in the diamond coatings.

Synthetic diamond coatings with intermediate bonding layers and methods

This invention discloses new and improved multi-layer coatings for gas turbine engine parts that are exposed to elevated temperatures, such as blades and vanes in the high pressure compressor and turbine of multi-stage aircraft engines, by applying a diamond film over columnar thermal barrier coatings such as yttria-stabilized zirconia, improving the erosion resistance of the thermal barrier coating.

This invention relates to methods of making new and improved diamond, 'diamond-like carbon' (a-C) and 'diamond-like hydrocarbon' (a-C:H) coatings bonded to substrates by using intermediate bonding layers comprising amorphous 'glassy' metals, engineered to reduce the residual stress in the diamond coatings, and to articles of manufacture made using such methods.

A game ball (10) including a large collapsible outer shell (12) partially filled with filler material (14). The game ball (10) includes a selectively closeable aperture (22) adapted to permit insertion and removal of filler material (14) within the outer shell (12). The game ball (10) also includes at least one air vent (34) through the outer shell (12). A game can be played with the ball (10) by having players (16) simultaneously grasp opposing sides of the ball (10) while attempting to move the ball (10) toward a goal area (38,40) and resist movement of the ball (10) toward an opponent's goal area (38,40).
