The apparatus further comprises a disperser device, operatively associated with the rotor mechanism, for dispersing the plurality of gas bubbles from the rotor mechanism within the vessel, and wherein the gas bubbles create an oily froth on the top of the raw water, and a skim tray, positioned about the rotor mechanism, is provided for removing the oily froth from the top of the raw water as well as a secondary skimmer positioned within the skim tray. In one preferred embodiment, an external skim tank that is configured to deliver a gas to the rotor mechanism and wherein the external skim tank is configured to receive the oily froth from the secondary skimmer.

  • Patent number: 8029678
    Abstract: The invention concerns a water treatment method including a step of clarification, followed by an ozonization step and at least one filtration step, wherein after the clarification step (1), one fraction of the main stream of water is diverted (9); said diverted fraction of water is circulated counter-current (7) to an ozone-rich carrier gas, and the ozone-enriched fraction of water is diluted in the main stream.

    Abstract: In some embodiments, a system may reduce contaminants in water. A system may include a biofilm in a container. The biofilm may be formed from one or more bacteria coupled to one or more substrates. The bacteria may be selected to maximize the reduction of contaminants in water. The system may include one or more bacteria generators to provide bacteria to the biofilm and/or one or more air sources to provide an air bubble stream to the container and/or the bacteria generator. In some embodiments, bacteria may be preserved in a starvation phase. Bacteria may be incubated until they reach a starvation phase. The bacteria may then be preserved as beads or immobilized on a substrate. The preserved bacteria may be used in a system for the reduction of contaminants in water.

  • Publication number: 20110233147
    Abstract: A method produces high-purity water from low-purity water, which is not limited to seawater but includes sewage. The method includes having one or more types of gases capable of forming gas hydrates and low-purity water come into contact under conditions in which the temperature is higher than the freezing point of the low-purity water and the gas hydrates can be formed, thereby producing solid gas hydrates which are suspended in the low-purity water. The low-purity water used in the gas hydrate formation process is removed while substantially maintaining the gas hydrate state. Components adhered to the gas hydrates are cleansed with cleansing water; and by increasing the temperature in the gas hydrate state or decreasing the pressure in the gas hydrate state, the gas hydrates are decomposed into a gas and high-purity water.

  • Patent number: 8025807
    Abstract: A processor for decontaminating devices is comprised of a chamber for holding devices and a circulation system to circulate a microbial decontamination fluid through the chamber. A water filtration system filters water used in the processor. The water filtration system has a water line connectable to a source of pressurized water. A water decontamination system fluidly communicates with the source of water and the processor. The water decontamination system has a water circulation path and a tank located within the water circulation path. Means are provided to circulate water along the water circulation path through the tank. A gas circulation path fluidly communicates with the tank. Conveying means is provided to convey gas along the gas circulation path through the tank. An ozone producing device is located along the gas circulation path to introduce ozone into gas flowing along the gas circulation path and through the tank.

  • Publication number: 20110226683
    Abstract: A sewage treatment system is revealed. Water with contaminants is drawn from sources to the sewage treatment system for automatic and fast water purification. Thus clean drinking water is generated. The water with contaminants is sent to a treatment tank by a motor. Then non-toxic and odorless chemicals are sprayed in the treatment tank. By stirring and mixing of movable blades, the contaminants are coagulated and precipitated into a funnel under the treatment tank to be discharged. Next clean water in the treatment tank is sent to a centrifuge separator to be filtered and dehydrated by centrifugation. Water comes out from the centrifuge separator is drinking water. The sewage is converted into clean water. The system can provide clean safe drinking water to regions without water treatment plants.

  • Patent number: 8017089
    Abstract: A method and apparatus for conducting supercritical wet oxidation reactions wherein any precipitated solids do not contact the solid side walls of the containment vessel so as to prevent any of these precipitated solids from adhering to or corrode the vessel walls is provided. To do this, a controlled, continuous flow of clean fluid, preferably under supercritical conditions, is introduced to the process so as to form a film-like, clean fluid surface between the physical containment vessel walls and the supercritical wet oxidation reactants.
