  • Patent number: 8048316
    Abstract: A method for subjecting a microorganism to a combination of ozone and irradiation of UV light which has a synergistic effect on the reduction of the microorganism that may be resistant to either ozone or UV light alone. In particular, Adenovirus and Naegleria fowleri, are significantly more reduced when subjected simultaneously to the combination of ozone and UV light than when subjected only to ozone or UV light, respectively.

  • Publication number: 20110233144
    Abstract: The present invention is directed to a method and apparatus for improved separation or clarification of solids from a solids-laden liquid. Entrained gasses can also be removed. A liquid to be treated is introduced into the inlet of a solid-liquid separator modified to include one or more sources of vibrational energy. The liquid to be treated is directed through a conduit within the separator. Preferably the conduit within the separator is configured into a tortuous flow path to assist in the separation of solids from the liquid. Vibrational energy is applied to the flow path, preferably through the flow path conduit. As solids fall out of solution, they are collected. The clarified liquid is also collected. A vacuum can be applied to the system to assist in moving the solid-liquid mixture through the system and to provide vacuum clarification. Electrocoagulation electrodes and gas sparging can also be employed.

  • Patent number: 8002992
    Abstract: A method for treating a liquid is disclosed using an apparatus having: (a) a pump volute or hydrocyclone, (b) a throat connected to the pump volute or hydrocyclone head, (c) a parabolic reflector having a vertex, a focus and an opening at the vertex, wherein the opening is connected to the throat such that the vertex and focus are axially aligned with the central axis and the focus is not located within the throat, and (d) a wave energy source having a first electrode within the pump volute or hydrocyclone head that extends into the throat along the central axis of the throat, and a second electrode extending into the parabolic reflector proximate to the focus wherein the second electrode is spaced apart and axially aligned with first electrode. The liquid is supplied to the pump volute or hydrocyclone head and is irradiated by the wave energy source.

  • Patent number: 7910006
    Abstract: The water is at the origin of an entire series of geological and climatic processes and is primarily the basis of all forms of life. Actually, it is the majority component of all living organisms (50% to 98%); the human body contains 70% of the total mass thereof. The biosphere in its entirety consists of 80% water. Although this may be one of the most highly examined liquids, its properties comprising numerous anomalies have not yet all been elucidated. It plays an essential role in the structure and metabolism of all living beings. This biological role is due to its physical and chemical properties that are out of the ordinary. Bernal and Flower established a rule defining that each oxygen atom has two hydrogen atoms as neighbors and each hydrogen bond contains one hydrogen atom. The separation of the liquid water molecules produces the formation of hydroxyl ion (OH?) and hydronium ions (H3O+), which hampers this rule.

  • Publication number: 20110011801
    Abstract: The present invention pertains to an effective system and method for reducing or eliminating the formation of scale in desalination systems. The system utilizes at least one pair of electrodes in direct contact with a liquid to induce an oscillating electric field directly in a portion of the liquid or a liquid stream of the desalination system. The electric field is capable of inducing bulk precipitation of ions, minerals, salts, particulates, contaminants or a combination thereof from the liquid stream.

  • Publication number: 20100320156
    Abstract: The present invention provides a method for oxidizing a substance (e.g., in a waste stream, drinking water, a paper pulp slurry, or on a surface), which uses free radicals and reactive species generated from multiple oxidants. The method comprises combining peroxynitrite or peroxynitrous acid and at least one additional oxidizing agent for a period of time sufficient to oxidize the substance of interest. The peroxynitrite or peroxynitrous acid preferably is formed by irradiation of nitrate ion and/or nitric acid (e.g., with UV or gamma rays). The yield of free radicals and reactive species, which are the intermediate species that perform the oxidation may be increased by addition of a catalysts, electromagnetic radiation, sonic waves, and/or electrolysis.
