摘要： A submersible aeration pump includes a motor housing, an air inlet conduit carried by the motor housing, a pump motor in the motor housing, a rotatable armature drivingly engaged by the pump motor and disposed in air communication with the air inlet conduit and at least one air discharge conduit carried by and disposed in air communication with the armature. Air is drawn from the air inlet conduit, through at least a portion of the armature and is discharged from the at least one air discharge conduit, respectively, by centrifugal force responsive to operation of the pump motor.

摘要： A wastewater treatment system for treating wastewater effluent flowing through a sewer pipe from a sewage treatment plant, and specially designed chlorine tablets for use in the treatment system. In a preferred embodiment the wastewater treatment system is characterized by a wastewater flow conduit which is mounted in the sewer pipe and a tablet loading neck, closed by a removable lid, extends upwardly from the wastewater flow conduit. A tablet support rod extends downwardly through the lid and tablet loading neck into the wastewater flow conduit. Multiple treatment tablets, each having a central opening, are slidably mounted on the tablet support rod in stacked relationship, and as the tablets in the wastewater flow conduit are dissolved by the flowing wastewater, the tablets in the tablet loading neck descend on the tablet support rod into the conduit, to replace the dissolved tablets. In another embodiment the tablet support rod is slidably mounted in the lid and biased upwardly and as the tablets are dissolved, the tablet support rod moves upwardly through the lid and is either visually inspected or attached to an alarm switch which activates an alarm to indicate the need for replacing tablets on the rod.

摘要： A pressure alarm for sewage treatment systems such as waste-water or sewage treatment tanks which require water level control. In a preferred embodiment the pressure alarm includes a pressure sensing apparatus which includes a tee or elbow located in a tank or system aerator air line, a nipple set into the tee leg of the tee or the elbow and a ball float fitted with a shaft or neck extending through the nipple and receiving an air deflector. According to the method of this invention, the air deflector projects into the run of the tee or the elbow responsive to floating of the ball float upwardly in a high water condition in the treatment tank or system. Extension of the air deflector into the run of the tee or the elbow causes a pressure drop through the tee or elbow as air is deflected from the run of the tee through the tee leg or elbow. A control system including a pressure-sensitive switch, is provided, typically on a conventional compressor or blower for sensing this pressure drop and sounding an audible and/or a visual alarm.

摘要： A sewage treatment system which includes a cylindrical treatment tank fitted with an air distribution system and an inverted, cone-shaped clarifier, wherein air is supplied to the aeration chamber of the treatment tank through the air distribution system by means of a compressor. The treatment tank is normally installed below the surface of the ground and the air distribution system includes downwardly-extending air drop lines, the plugged ends of which project at or below the plane of the bottom open end of the cone-shaped clarifier. The drop lines are provided with spaced air openings which face the clarifier and are located above the plane of the bottom open end of the clarifier, to facilitate optimum diffusion of air into the aeration chamber toward the clarifier from the drop lines, responsive to operation of the compressor.
