Abstract: Disclosed are a vent disclosed for a septic system, including a conduit configured to vent gas therefrom, including a leg configured to conceal a portion of, and convey gas from, the conduit, and a method of concealing a conduit configured to vent gas from a septic system including sizing the conduit, then mounting on the conduit a leg configured to convey gas from the conduit.

Abstract: An apparatus for associating a solution at an infinitely-variable level and/or flow rate with respect to an agent including an agent amount indicator that promotes agent-solution association adaptable for use in a chlorinator, or comparable component, of a fluid treatment plant. An embodiment configured according to the invention includes a chamber with an inlet and a vertically-inferior outlet. The level and flow of fluid in the chamber is regulated by a weir mounted on the outlet. Fluid in the chamber passes through an agent the retainer maintained in the chamber and washes over the agent, dissolving and depleting the agent. A magnetic follower on top of the agent urges the agent toward the bottom of the retainer. As the agent becomes depleted, the follower approaches the bottom of the retainer until it attains a predetermined distance from a sensor which activates a low-agent-supply alarm. If the alarm remains activated for a predetermined amount of time, a second alarm is activated.

Abstract: An array of sonic hydraulic nozzles for injecting a mixture of water with dissolved or suspended particulate into a chamber to form a continuous spray of spherical droplets. Low pressure areas form in the wakes of the droplets which promotes a phase change and evaporation upon being submerged in heat vortices created along the edges of the sonic shock waves. All dissolved and/or suspended solid particles in the mixture precipitate from the spray upon the vaporization of the water. Shortly thereafter, the particle-free vapor re-condenses into a dense water mist of substantially pure water, while releasing the excess heat captured in the evaporation vortices. The water mist then is absorbed by nucleating screens located above the nozzles. The screens concentrate the dense mist into water streams through a channel running out of the apparatus.

Abstract: An embodiment of a belt scraper constructed according to principles of the invention includes a blade mounted on a blade holder. The blade holder is mounted on a shaft. Each end of the shaft is retained by a pillow block. Each pillow block is mounted on a bracket. Each bracket mounts on a non-moving portion of a conveyor belt frame. The pillow blocks are adjusted to orient the blade relative to and urge the blade against a conveyor belt for optimal debris removal.

Abstract: A remote pump control apparatus and method that allows a septic tank service worker to physically control the end of the evacuation hose and operate a conventional pump which induces flow therein while servicing a septic tank including an actuator that mounts on and manipulates the flow control of the pump. The compressed fluid-driven actuator is controlled by a hand-held remote signal sender. A septic tank service worker depresses a switch on the hand-held remote signal sender and generates a signal which is received in a control box. The control box activates a solenoid which directs compressed fluid into one passage of a housing of the actuator, causing the actuator to manipulate the pump flow control in one direction, and into another passage, causing the actuator to manipulate the pump flow control in an opposite direction.

Abstract: A sewage treatment apparatus including a treatment tank with a floor, walls and having an upper aperture. A hopper having a clarifier chamber is centrally disposed in the treatment tank, maintained at a predetermined height above the treatment tank floor by hopper supports. A deflector cone is centrally disposed on the floor of the treatment tank, its vertex being received in the lower aperture of the hopper. The exterior of the hopper, the deflector cone and the inner walls of the treatment tank define an annular aerator chamber, subdivided into a plurality of aerator zones. Diffusers disposed in each aerator zone introduce oxygenation of and induce flow of sewage in the treatment tank. A cover mounted over the treatment tank aperture maintains a pressurized pocket of air above the sewage for increased oxygenation of the sewage. Treated sewage passes from the aerator zones into the clarifier chamber, then into the environment.

Abstract: A method for introducing materials into a medium including creating passages in the medium with a blast of a pure preselected compressed gas that encourages activity of a preselected entity within or introduced into the medium and maintaining the passages with preselected materials for maintaining the passages.
