Abstract
A water purification system includes a settling tank to allow small particulate material to settle on the bottom of a conical section. The liquid from the bottom of the tank is pulled to the top of a drum bagger which is a depressurized filtration apparatus. The drum bagger includes a filter bag separated from the outer walls of a drum and a vacuum source at the bottom of the drum adapted to suck liquid from the bottom of the drum. The vacuum source is an eductor which creates a vacuum by pumping liquid through the eductor either to a holding tank or back to the settling tank. This drum bagger separates the liquid from solid material and can even dry the solid material reducing disposal costs.
Claims11
A drum bagger including a vacuum vessel having a top, a bottom and a side wall;
- a liquid inlet through the top of said tank;
- valve means adapted to close said liquid inlet;
- a filter basket adapted to support a filter medium said bracket open to said inlet and separated from said bottom and side walls of said vacuum vessel;
- a venturi eductor outside and below said bottom wall communicating with an interior of said vacuum vessel through said bottom wall;
- a pump adapted to force liquid through said eductor to create a suction through said venturi eductor at the bottom of said vacuum vessel to thereby draw liquid from the interior of said drum bagger such that when said valve means is closed said venturi acts to draw a vacuum in the interior of said tank to remove liquid and to dry material collected in said filter basket.
A water purification system including a settling tank having a particulate collection point at the bottom of said settling tank;
- an outlet from said bottom of said settling tank leading to an inlet of a drum bagger said drum bagger including a vacuum vessel having a top, bottom and side wall, a water inlet passing through said top wall leading to the interior surface of a filtration medium support, said filtration medium support separated from the bottom and side walls of said vacuum vessel;
- a vacuum eductor outside and below said vacuum vessel adapted to suck water from said vacuum vessel through the bottom of said drum bagger;
- a pump adapted to pass purified liquid from said settling tank and pump a portion of said liquid through said vacuum eductor to thereby create a suction within said vacuum vessel and draw liquid from said drum bagger.
A method of purifying a particulate containing liquid comprising admitting said liquid to the top of a drum bagger into a filter medium separated from the side walls of said drum bagger, sealing said drum bagger, drawing a vacuum through the bottom of said bagger using an eductor by pumping liquid through said eductor thereby sucking liquid through said filtration medium and through said eductor.
A water purification system including a settling tank having a particulate collection point at the bottom of said settling tank;
- an outlet from said bottom of said settling tank leading to an inlet of a drum bagger said drum bagger comprising a vacuum vessel including a top, bottom and side wall, a water inlet passing through said top wall leading to the interior surface of a filtration medium support, said filtration medium support separated from the bottom and side walls of said vacuum vessel;
- a vacuum eductor through the bottom of said vacuum vessel adapted to suck water from said vacuum vessel;
- a pump adapted to pass unpurified liquid through said vacuum eductor providing a suction within said vacuum vessel and draw liquid from said drum bagger;
- means to direct unpurified liquid from said pump to one of said eductor and said settling tank.
