Abstract: A system and method is provided for optimizing chemical additions, mixing energy and other variables while treating a contaminated liquid stream. Samples from the contaminated liquid stream are tested to determine the optimal parameter for each variable, including type and amount of chemistry added, chemistry sequence, mixing energy and time, temperature, pressurization, etc. A system of mixing devices, flotation chamber, and other components are designed and modified to achieve optimal results based on the prior testing. The system can be modified over time in response to the changing contaminated liquid stream.

Abstract: A system for separating particles from a contaminated liquid stream includes an apparatus for mixing the liquid with one or more separation enhancement additives and gases. A pressure reducing device having a flow restrictor element within an enlarged tube receives the mixed liquid and creates bubble laden floccs by reducing the pressure of the liquid stream. The pressure reducing device empties into a bloom chamber of a flotation tank, where the bubble laden floccs are directed upwardly to an upper portion of the flotation tank. The flotation tank is configured such that the bubble laden floccs circulate within the upper portion of the flotation tank until they float to the upper surface, while decontaminated liquid flows to a lower portion of the tank for removal. A skimmer removes the floated contaminated floccs from the upper surface of the flotation tank into a dewatering apparatus.

Abstract: A method and system for utilizing electromagnetic energy to inhibit, prevent, reverse, or alter the formation of rust or scale on various liquid contacting surfaces is disclosed. An electromagnetic signal at a frequency related to the energy absorption/emission characteristics of the liquid being treated are directed into the liquid. The frequency of the treatment signal, preferably between 0.1 KHz and 1000 MHz, may be changed if the absorption/emission profile of the liquid changes during treatment.
