  • Patent number: 10365214
    Abstract: The concentration of mercury in a sample is measured by a reader secured to a camera-containing mobile electronic device. The reader has holders for sample and control solutions. First and second light sources emitting light at different colors illuminate the sample and control holders. Each holder contains gold nanoparticles, thymine-rich aptamers, and sodium chloride. The light sources illuminate the sample and control holders. An image is captured of the transmitted light through the sample and control holders, wherein the image comprises two control regions of interest and two sample regions of interest. The device calculates the intensity of the two control regions of interest and the two sample regions of interest and generates intensity ratios for the sample and control, respectively, at each color. The device calculates a normalized color ratio based on the intensity ratios and outputs a concentration of mercury based on the normalized color ratio.

  • Patent number: 9061267
    Abstract: Sorbent comprising a solid support material, the surface of which comprises a first residue comprising a pyridyl ring, whose hydrogen atoms may be substituted, and a second residue comprising a carboxyl group. The first and second residues may be attached to a polymer which coats a carrier, but which polymer is not covalently grafted to the carrier. The sorbents can be used to separate or to increase the concentration and/or purity of a protein or peptide from a mixture containing the same.

  • Publication number: 20150144564
    Abstract: Disclosed herein are embodiments of a system for treating water. The system comprises a biochar inlet, and optionally a metal salt inlet, ozone inlet, organic carbon compound inlet or any combination thereof. The biochar may be produced by biomass pyrolysis and the pyrolysis may be coupled to energy generation. The system also comprises a filtration device, such as a reactive filtration device. The system produces a treated water stream and a reject stream, which may be further separated into a recycled water stream and a solid product. The solid product may be suitable as a soil amendment for application to agricultural land, or for recycling. A method for using the system to treat water also is disclosed.

  • Patent number: 9039899
    Abstract: Separation processes using osmotically driven membrane systems are disclosed generally involving the extraction of solvent from a first solution to concentrate solute by using a second concentrated solution to draw the solvent from the first solution across a semi-permeable membrane. Enhanced efficiency may result from using low grade waste heat from industrial or commercial sources. Pre-treatment and post-treatment may also enhance the osmotically driven membrane processes.

  • Publication number: 20150129503
    Abstract: Method of removing dissolved organic carbons from raw water, containing suspended and/or colloidal matter in a suspended ion exchange process, includes: feeding the water into a plug flow reactor at a rate of at least 500 m3/h, adding an anion exchange material to the liquid at the inlet of the reactor, suspending the anion exchange material in the water, transporting the water and the suspended anion exchange material under plug flow conditions to an outlet of the reactor after a predetermined residence time, feeding the water and the suspended anion exchange material to a separator and feeding treated water and anion exchange material from a reactor outlet to a separator, wherein the concentration of the anion exchange material in the reactor is smaller than 20 ml/l, and the residence time of the anion exchange material in the reactor is lower 30 minutes.

  • Publication number: 20150114908
    Abstract: In accordance with one embodiment, a process is described for a water treatment process in which water produced from a fuel production process is treated with recycled biochar. In accordance with one aspect, process water is passed through activated carbon generated by the biomass pyrolysis and gasification. In accordance with another aspect, the process water is treated to expel gaseous compounds within the process water. In this manner both inorganics, light organics and heavy organics can be removed from the process water. No fermentation is involved.

  • Patent number: 8999154
    Abstract: Disclosed is a water treatment apparatus for treating Lake Okeechobee water. The treatment apparatus operates on a continuous flow of water which is subjected to hydrodynamic waves, acoustic ultrasonic waves in combination with injected ozone and electrolysis. The treatment system provides a cost efficient and environmentally friendly process for cleaning contaminated water that is directed into estuaries, lagoons, intracoastal waterway, everglades, and the ocean. Treatment includes addressing various levels of contaminants such as aerobic bacteria, often called a green slime that produces a bio-film. The apparatus can be mounted on a vessel to permit targeting of algae blooms.
