Abstract: The invention is a system of raising an effluent level of a septic system drainfield. The system includes an outer housing comprising an inlet in fluid communication with a septic tank. The housing further includes an outlet that enables the effluent to exit the system at a higher elevation. The housing interior includes a hollow insert that extends above a bottom surface of the housing. A baffle is positioned within the interior of the housing to surround the insert, dividing the housing interior into two compartments with insert passing therethrough. In use, wastewater effluent enters the housing interior from a septic tank and gravity falls into the bottom of the housing. An air pump can then be initiated to pump air into the system, which lifts the effluent into the housing upper compartment, where it will exit the system at a higher elevation.

Abstract: An air extractor including a liquid cavity, an air extracting cavity, a connection channel, a drainage channel, and an air extracting channel. The liquid cavity contains rotating liquid and the air extracting cavity has liquid therein. The liquid in the air extracting cavity is in communication with the liquid cavity through the connection channel, the liquid cavity drains the liquid through the drainage channel. The air extracting cavity is in communication with an object to be subjected to air extraction through the air extracting channel and air in the object to be subjected to air extraction flows through the air extracting channel into the air extracting cavity.

Abstract: A valve assembly for an inflation system that includes a pressure relief valve and a vent valve. The pressure relief valve has a pressure relief housing and a pressure relief valve poppet. The pressure relief housing defines a first pressure relief cavity that is disposed between a first end wall defining a first flow port and a first wall defining a passageway and a second pressure relief cavity disposed between the first wall and a second wall. The pressure relief valve poppet is movably disposed within the first pressure relief cavity and the second pressure relief cavity. The vent valve has a vent housing and a vent valve poppet. The vent housing defines a vent cavity that is disposed between the second wall defining a vent flow port and a second end wall. The vent valve poppet is movably disposed within the vent cavity.

Abstract: A gas lift pump apparatus for treating ballast water includes a column through which a liquid medium, such as seawater, may be pumped by gas lift. The apparatus includes a delivery device for delivering a flow of a gas into the liquid medium, and a resonance chamber that generates ultrasonic energy therein by the flow of the gas therethrough. The apparatus is operable to launch the ultrasonic energy into the liquid medium in the column.

Abstract: A sump pump tracking system includes a pressure sensor including a first port and a second port, a tube extending from the first port, a processor in communication with the pressure sensor, a remote server in communication with the pressure sensor, and a memory in communication with the processor. The memory includes instructions, that when executed by the processor, cause the processor to: receive a water pressure reading from the first port; calculate a corresponding air pressure from the water pressure reading from the first port; and determine the pressure differential between the first port and the second port. The server is configured to be programmed with an alarm threshold limit. The pressure sensor communicates the pressure differentials to the server. The server is configured to compare the pressure differential with the alarm threshold limit and send an alert if the pressure differential is above the alarm threshold limit.

Abstract: An airlift pump comprising a hollow, cylindrical main body having an injection hole near the bottom end, a channel routed in the outside surface of the main body and extending continuously from the injection hole to the top end, and an air tube seated in the channel and bonded to the main body. The air tube comprises an injection end having an elbow forming an injection angle such that the air is injection into the main body in a downward direction toward the bottom end. The air tube further comprises a receiving end extending past the top end of the main body and connecting to air supply tubing. The pump has a restricted lateral width enabling the pump to fit inside the narrow monitoring wells typical in the groundwater monitoring industry.
