  • Patent number: 8840845
    Abstract: Provided herein are systems and methods for the treatment and purification of fluids (e.g., water) using a light-emitting diode (LED) light source. In one embodiment, for example, there is provided a fluid flow conduit having an LED light source and a photo-catalytic material disposed therein. The LED light source emits ultraviolet light with a peak wavelength between about 265 nm and about 400 nm. In operation, the photo-catalytic material absorbs the ultraviolet light from the LED light source, and releases free radicals into the fluid. The free radicals then degrade organic substances (e.g., bacteria) in the fluid.

  • Patent number: 8834805
    Abstract: In order to disinfect and to detoxify a fluid, a photoreactor contains at least two light sources. One light source activates the catalytic function of a semiconductor material in the fluid to reduce the concentration of contaminants in the fluid, such as by breaking down organic contaminants into non-toxic compounds. A second light source acts directly on living biological entities to sterilize or kill them and thereby disinfect the fluid, and can also serve to activate a semiconductor photocatalyst that in turn causes further damage to biological contaminants. The semiconductor photocatalyst is desirably attached to an optically transmitting fiber substrate in the fluid. The second light source in one embodiment is external to the fluid and illuminates the photocatalyst through transmitting surfaces in a fluid containment vessel. The light sources can comprise respective sets of plural LEDs.

  • Patent number: 8828240
    Abstract: A method to purify water includes the steps of providing a septic tank to hold unpurified water and having an outlet to provide a water stream for processing, and processing the water in an electrocoagulation and flocculation reactor that uses electrical energy to convert dissolved solid material in the water stream into suspended particulate form that can be subsequently filtered and separated out. The method continues with introducing air into the water stream to promote aerobic processing of contaminants and to assist in agglomeration and flocculation of suspended solid material, filtering the water stream to separate suspended solid material from the stream and to adsorb some of its dissolved contaminants, and processing the water stream with a reverse osmosis processor that provides a reject stream that provides water back to the septic tank and a recycle stream that provides unpurified water back to the water stream exiting the septic tank.

  • Patent number: 8795498
    Abstract: The invention comprises two key components: dielectrophoresis (DEP) and reversible binding surfaces. DEP has become an important tool for trapping dielectric particles. Moreover, DEP can manipulate cell movement as dictated by the intrinsic dielectric constant of the cell without modification. DEP therefore provides a mechanism by which to force targets in a flow channel to a reversible binding surface. By building selectivity into the binding surface, the capacity to choose which targets can be held after the dielectric field is turned off, providing a separation strategy that does not suffer from fouling issues, as large foulants can freely pass over the surface through the flow channel.

  • Patent number: 8691097
    Abstract: The system and method is directed to improved separation or clarification of solids from a solids-laden liquid and removal of entrained gasses. 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 is directed through a conduit within the separator. This conduit can be 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 along with height adjustable weirs and an oil accumulator.

  • Patent number: 8685238
    Abstract: Embodiments of the invention relate to systems and methods for a solar and/or AC current powered water disinfection system that is sized for portable use and is specifically tailored for use in under-developed areas of the world or in areas where natural disasters have occurred. Embodiments herein disclosed provide for a system that utilizes an ultraviolet light that is operatively coupled to a pump, inverter, battery, and a charge converter that is adapted for use with a solar panel or AC current. The system is placed into a storage container, or the like, and the water in the storage container is pumped through the ultraviolet light, which kills most waterborne, water-washed, and water-based diseases.

  • Patent number: 8679351
    Abstract: A water decontaminization system and method which utilizes an apparatus for producing hydroxyl ions through hydrolysis of water molecules to oxydize contaminents in the water. The apparatus includes a water chamber with an input water conduit and an output water conduit to establish a water flow in the chamber, in which electrodes positioned in the water chamber apply a voltage potential which causes electric current to flow through the water to create hydroxyl ions in the water, in a manner effective to kill contaminents such as viruses, bacteria, algae, organic substances, etc.

  • Patent number: 8663444
    Abstract: Prolongation of the lifetime for reduced water is attempted. Production water that presents alkalinity is produced by utilizing raw water with ionized metallic minerals being dissolved therein and hydrogen gas H2. When inpouring the hydrogen gas together with the raw water into an electromagnetic portion in the apparatus, the hydrogen gas is bubbled and ionized to produce ions. The gas bubbles of the ionized hydrogen-ions are miniaturized. By making a metallic mineral as a core, hydrides (H?), which are negative ions in the hydrogen ions, coordinate on the periphery of that core. The metallic minerals which are complex-ionized (complex-ionized metallic minerals) based on a fact that the hydrides coordinate are dissolved in the water stably for long period of time, so that production water which presents alkalinity, that is, reduced water can be obtained. The reduced water can be utilized as drinking water. A metal container is preferable for a refilling container.
