  • Publication number: 20130270181
    Abstract: Selenium in the form of a reduced species such as selenocyanate is oxidized to produce an oxidized selenium species such as selenate or selenite, and then a biological reduction process is used to remove selenium from the oxidized selenium species. In an example, a chemical oxidant is added to a wastewater containing selenocyanate to produce selenate and selenite. The partially treated wastewater is then fed to a reactor containing a fixed media supporting a biofilm with selenium reducing organisms. The selenium in the selenate and selenite is reduced to an insoluble form of selenium, such as elemental selenium, which precipitates from the wastewater.

  • Patent number: 8557107
    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.

    Abstract: One embodiment of a method to system for enhancing TOC removal while maintaining membrane filter performance is the implementation of a dual pH control system. This embodiment will enhance the ability to maximize TOC removal while maintaining optimum membrane filter performance. By adjusting pH, dosing a chemical coagulant and incorporating liquid-solids separation, a considerably higher degree of TOC removal is possible. By adjusting pH again after liquid-solids separation this embodiment can drastically increase the efficiency of the membrane microfiltration/ultrafiltration system. Thus pH control for soluble organic removal is critical. This pH level however may not be the ideal set point for minimizing membrane fouling which is the basis for this embodiment. An example: the pH set point for optimum soluble organic removal is designated to be 5.5. However, the optimum pH set point for optimum membrane performance is 7.0.

    Abstract: A method and system for processing fluoride-containing wastewater includes treating the wastewater with brine (waste) created by the regeneration process implemented by in ion exchanging water softener. The brine, which is typically disposed of, contains both calcium and magnesium salts, in varying concentrations and ratios. The regeneration process brine is added to the fluoride-containing wastewater within a reaction tank, and the fluoride ion concentration is monitored. When the fluoride ion concentration falls below a predetermined level (e.g., 15 ppm), the flow of regeneration process brine is stopped. A pH controller monitors the pH within the reaction tank, and adds a basic agent to ensure that the pH remains above a predetermined level (e.g., pH>9). The pH control results in a clear effluent, and a sludge having a high settling rate and a high dewater ability.

    Abstract: The invention is an apparatus and method for treating fluid in a pool, spa, or water tank, etc., using ozone and treated air. A fluid filter is placed in an auxiliary reservoir or a smaller fluid tank located in or next to the pool, spa, or main water tank. An ozone generator pumps a combination of ozone and air into the smaller fluid tank. Fluid in the smaller fluid tank passes through a filter and back into the main reservoir without the use of any fluid pump. More specifically, a vertical lift tube is placed beneath the smaller fluid tank so that the open top of the lift tube is within the smaller fluid tank. Fluid from the main reservoir is piped to the bottom of the lift tube. Ozone and air from the ozone generator is also piped into the lift tube near its bottom. The fluid flows through the filter due to the effect of ozone and air bubbles released by a diffuser at the bottom of the lift tube.

  • Publication number: 20130118994
    Abstract: Systems and methods have been developed for treating waste water and produced water, so as to remove contaminants therefrom. The systems and methods allow specifically for the removal of contaminants from produced water from oil and gas wells, fracturing flow-back water, and water- or brine-based drilling fluids. The water is treated by contacting the contaminated fluid with ozone after contacting the fluid with a diffused air system to generate small bubbles for entrainment of some contaminants. Thereafter, the water is contacted with an electro-coagulation system in order to remove flocculants and adjust the pH and the total dissolved solids levels of the fluid.

  • Publication number: 20130106003
    Abstract: The invention relates to an apparatus (1) for feeding chlorine dioxide to water, comprising a first feed pipe (5a) for feeding in a first reaction component, comprising a second feed pipe (5b) for feeding in a second reaction component, comprising a mixing tube (2) for mixing and reacting the two reaction components to chlorine dioxide, at one end of which the two feed pipes (5a, 5b) join and at the other end of which is arranged a suction chamber (4) into which feed water to be enriched with chlorine dioxide can be sprayed by means of a nozzle (12), and comprising an exit water pipe (13) leading downstream from the suction chamber (4). This object is further to develop such an apparatus so that it is simple and has a robust design and permits different chlorine dioxide syntheses based on two reaction components to be carried out without danger.

  • Publication number: 20130105377
    Abstract: A method and system for reversibly converting water between an initial ionic strength and an increased ionic strength, using a switchable additive, is described. The disclosed method and system can be used, for example, in distillation-free removal of water from solvents, solutes, or solutions. Following extraction of a solute from a medium by dissolving it in water, the solute can then be isolated from the aqueous solution or “salted-out” by converting the water to a solution having an increased ionic strength. The solute then separates from the increased ionic strength solution as a separate phase. Once the solute is, for example, decanted off, the increased ionic strength aqueous solution can be converted back to water having its original ionic strength and reused. Switching from lower to higher ionic strength is readily achieved using low energy methods such as bubbling with CO2, CS2 or COS.
