  • Patent number: 7879230
    Abstract: A vacuum-actuated liquid chlorine dispenser for use in an aerobic treatment system. Effluent is diverted from a discharge pipe in an aerobic treatment system into an inlet of a venturi chamber. The resulting pressure differential resulting from effluent flowing through the venturi chamber is communicated to a dosage container, which results in disinfectant flow from a reservoir into the dosage container until the volume of disinfectant contained by the dosage container causes a pressure control device, such as a float valve, to inhibit further pressure communication. Thereafter, the accumulated disinfectant within the dosage container egresses through a disinfectant outlet that may include a flow regulation device such as a drip emitter or check valve. The present invention allows for more regular dosing of known and accurate disinfectant amounts following each pumping cycle of the aerobic treatment system.

  • Patent number: 7874462
    Abstract: A pressure-actuated disinfectant dispenser and method for treating wastewater in an aerobic treatment system. The dispenser includes a reservoir for holding a disinfectant supply and a dosage container for holding a dosage of disinfectant. The container is positioned within the reservoir and has a flow-regulated path for fluid communication from the reservoir into the container. The invention also includes actuation means for increasing the pressure within the dosage container to force disinfectant therefrom, and a discharge assembly for discharging fluid from the dosage container into said storage tank.
