Waste water treatment systems and methods

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.

What is claimed is: 
     
         1 . An apparatus comprising:
 a spray head assembly having a hydrodynamic mixing chamber provided therein;   a nozzle coupled to the spray head assembly; and   a multi-port manifold adapted to attach the spray head assembly to an end of a conduit that carries waste water from a well, wherein the multi-port manifold is configured to conduct waste water from the conduit to the hydrodynamic mixing chamber in the spray head assembly, and further configured to couple a supply of additive to the hydrodynamic mixing chamber in the spray head assembly,   wherein the hydrodynamic mixing chamber is configured to obtain a mixture by mixing one or more fluids received from the multi-port manifold, and   wherein the nozzle is configured to disperse the mixture as a spray on to a surface of a body of waste water maintained by the well or a wall of the well.
