Abstract: Systems, apparatus and methods are described that control and manage wastewater collection and treatment. One or more sensors monitor and measure levels of contaminants, other chemicals and or environmental conditions in a well of a collection station and/or in inflow and/or outflow mains. An additive that can include one or more of ozone, oxygen, a bioagent, bleach, peroxide and other chemicals, and selected to treat chemicals and/or contaminants in wastewater, can be mixed with waste water in the well and the main. A dispersion assembly deployed within the collection station is adapted to mix and spray the waste water and additive onto a wall of the well or surface of a body of wastewater in the well. A processor configured to control the rate at which the additive is provided to the dispersion assembly or force main based on measurements of contaminants received from the first and second sensors.

Abstract: Systems, apparatus and methods are described that control and manage wastewater collection and treatment. A method for treating waste water comprises receiving from a vessel, a portion of a body of fluid for treatment at an input port, providing the oxidizing gas under pneumatic or vacuum pressure to a mixing chamber, where the oxidizing gas comprises one or more of oxygen and ozone, and conducting the portion of the fluid to the mixing chamber. The fluid and oxidizing gas may be mixed to obtain treated fluid which may be reintroduced to the vessel.

Abstract: A method, an apparatus, and a computer program product for treating fracking fluids are provided in which a dispersion system receives a portion of a body of fracking fluid collected in a well. The dispersion system may comprise a hydrodynamic mixing chamber and a nozzle. An additive comprising one or more of ozone and oxygen may be mixed with a portion of collected fluid passing through the mixing chamber. The nozzle may disperse a mixture of the collected fluid and additive received from the mixing chamber. The system may comprise a controller having at least one processor configured to monitor the level of the additive or a contaminant in the well. The processor may be configured to cause a portion of the fluid to be pumped from the well through an outflow main when the level of fluid in the well exceeds a threshold level.

Abstract: Systems, apparatus and methods are described that can be used for cleaning wells using unfiltered fluids and fluids that contain solid matter. A spray head assembly mounted in a pumping station comprises a hydrodynamic mixing chamber configured to create turbulence in a fluid received from a pump. The pump draws a fluid from a well of the pumping station and provides a pressurized stream of the fluid to a pipe. A nozzle associated with an outlet of the mixing chamber, receives the mixed fluid from the hydrodynamic mixing chamber and the nozzle disperses the mixed fluid to the surface of a body of the fluid in the well.

Abstract: Systems, apparatus and methods are described that control and manage water collection and treatment. One or more sensors monitor and measure levels of contaminants, other chemicals and or environmental conditions in a well of a tank, well and/or collection station and/or in inflow and/or outflow mains. An additive that can include one or more of ozone, oxygen, a bioagent, bleach, peroxide and other chemicals, and selected to treat chemicals and/or contaminants in water, can be mixed with water in the well and the main. An infusion assembly deployed within the tank is adapted to mix the water and additive into a body of water in the well. A processor configured to control the rate at which the additive is provided to the infusion assembly or force main based on measurements of contaminants received from the first and second sensors.

Abstract: Systems, apparatus and methods are described that can be used for cleaning wells using unfiltered fluids and fluids that contain solid matter. Spray nozzles cooperate with deflectors to direct and outflow of the apparatus to surfaces to be cleaned. The apparatus comprises a mixer having an inner chamber, an inlet and a plurality of outlets. Deflectors are attached to associated outlets. The inner chamber has an impact surface located opposite the inlet, the impact surface redirecting the flow of fluid proportionately to the outlets and minimizes eddies in the flow of fluid. The deflectors generate a force from the fluid flow that includes rotational and/or translational components sufficient to cause rotation about a first axis and/or translation along a second axis.

Abstract: A roller screen is retrofitted to the lower edge of a retractable door, which screen is the same width as the door and the free end of which is removeably attached to the floor adjacent the lower edge of the door. The roller screen has a driving spring which is wound up as the retractable door opens and the screen is drawn out and which acts to roll up the screen as the door is closed. The free end of the screen is attached to the floor adjacent the lower edge of the door by connectors which can be uncoupled to allow access. The screen can also be built into the lower edge of a retractable door and its vertical edges can be retained in the same track which guides the opening door.
