  • 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.

  • Publication number: 20130228522
    Abstract: A system is provided for removing arsenic from water to safe levels at or below the EPA standards. The system is a hybrid spouted vessel/fixed bed filter system that significantly enhances/improves arsenic removal for drinking water using zero-valent iron (ZVI) particles. Movement of the circulating, iron-containing particles in a dense moving bed that forms on the spouted vessel bottom creates an abrasive “self-polishing” action among them that continuously generates colloidal iron corrosion products. This material then circulates with the water in the vessel and is removed and concentrated in a fixed bed filter. The colloidal material captured and immobilized in the filter has been shown to remove arsenic from contaminated water at very rapid rates.

  • Patent number: 8506810
    Abstract: A process and an apparatus for low-emission storage of biodegradable materials by means of aeration, without aerobic conditions materializing in the material, permits a more consistent feed of the downstream stages in the process. Aeration inhibits methanogenesis and the risk potential of an explosive gas mixture forming in the storage vessel or in the components of the system exhausting waste gas. Closed loop control of the aeration adapts the rate of aeration to the biological activity in the stored material and minimizes air input so as to minimize the loss of methanogenesis potential by aerobic conversion of the matter whilst minimizing the energy required for aeration. The process is characterized in that controlling the aeration in the storage vessel inhibits relevant methanogenesis.

  • Publication number: 20130161264
    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.

The precipitated phosphorus and other solids or sludge produced from the chemical treatment portion may be recycled upstream for reuse in the primary, secondary, and/or tertiary treatment stages. Such recycle may reduce the amount of added chemicals required in the tertiary treatment stage to phosphorus or other pollutants to desired amounts.

  • Patent number: 8097153
    Abstract: A device, system and method for exchanging components between first and second fluids by direct contact in a microfluidic channel. The fluids flow as thin layers in the channel. One of the fluids is passed through a filter upon exiting the channel and is recycled through a secondary processor which changes the fluid's properties. The recycled fluid is reused for further exchange. The filter excludes blood cells from the recycled fluid and prevents or limits clogging of the filter. The secondary processor removes metabolic waste and water by diafiltration.

  • Patent number: 8083706
    Abstract: The present invention is directed to devices, systems and methods for removing undesirable materials from a sample fluid by contact with a second fluid. The sample fluid flows as a thin layer adjacent to, or between, concurrently flowing layers of the second fluid, without an intervening membrane. In various embodiments, a secondary separator is used to restrict the removal of desirable substances and effect the removal of undesirable substances from blood. The invention is useful in a variety of situations where a sample fluid is to be purified via a diffusion mechanism against an extractor fluid. Moreover, the invention may be used for the removal of components from a sample fluid that vary in size. When blood is the sample fluid, for example, this may include the removal of ‘small’ molecules, ‘middle’ molecules, macromolecules, macromolecular aggregates, and cells, from the blood sample to the extractor fluid.
