Abstract: Wastewater from industrial processes commonly contains dissolved metals which require removal in order to meet discharge limits. The metal precipitant IE 061 may be utilized along with Floccin Agents™ for the removal of dissolved metals. The method here described indicates how to determine the appropriate dosage of IE061 metal precipitant and Floccin Agents™ required to treat the water. The method utilizes pH adjustment to an insoluble level for metals of concern. IE061 is then incrementally added to the water until the metals have precipitated utilizing oxidative state as an indicator of level of soluble metals. Required concentrations are determined by adding precipitant until the oxidative state indicates that no further precipitation is achievable. A Floccin Agent™ is then added in measured incremental steps in order to coagulate, flocculate and encapsulate the insoluble metals. The Floccin Agent™ is added incrementally to determine the concentration that yields acceptable metals removal.

Abstract: An apparatus for oxygenating and mixing a body of liquid includes an impeller rotating about a vertical axis and driven by a submersible motor. The impeller is incased in a housing with intake ports for both oxygen and water. Ports are located around the circumference of the housing such that the oxygen infused water may exit the housing in a radial direction and be dispersed across the tank before the pockets of oxygen rise to the surface. The motor and impeller housing are mounted to a horizontally positioned plate which is suspended from a float by adjustable chains or cables allowing variance in the depth of submersion for use in lagoons. Alternatively the unit may be mounted to the bottom of a tank or basin in applications where permanent installation is feasible such as in tanks. Pure oxygen is supplied from a source outside the body of water and is of a purity level that allows highly efficient transfer of oxygen to the water receiving treatment.

Abstract: A composition of ingredients and application process that enables the removal of contaminants from water or wastewaters, the composition when added and mixed with water(s) sequences to coagulate, flocculates and ion exchange with the composite materials. The application process is the addition of the composite material to water or wastewater where the contaminated materials are removed from the water(s) and contained in a solid material for disposal. The application is for clarification of potable waters for solids, clarification and settling aid for municipal wastewater waters, and contaminant and solids removal from industrial wastewaters.

Abstract: A highly efficient impeller apparatus for mixing concentrated oxygen in a liquid-filled pond, pool or lagoon. The downward and outward direction of liquid flow, coupled with optimally small bubbles produced through injection holes in tubes mounted on the impeller blades, optimizes the absorption of oxygen by the liquid. A rigid shroud surrounding the impeller constrains the liquid motion to axial, rather than radial, flow to ensure efficient mixing and minimize the electrical load requirements. The impeller drive may powered by a solar panel and battery combination, or by electrical utility service, or by a combination thereof.
