The method further involving pumping the warm waste material to a separation mechanism, such as a dryer, that separates a portion of the solid material (e.g., cuttings) from a portion of the liquid material (e.g., drilling fluid). The method may further involve mixing the separated solid material with a bioremediation agent.Type: ApplicationFiled: December 18, 2013Publication date: June 26, 2014Inventor: Mark Joseph Mathis

Patent number: 8747764Abstract: An inline intravenous (IV) fluid sterilization system can be located within directly upstream of the patient's access point, downstream of any breach points, so as to ensure fluid sterility. The chamber space between the walls is accessed by a fluid inlet port and a fluid outlet port between which the fluid flows. The inlet port is connected to a conduit/tubing from the fluid source and the outlet port is interconnected with a conduit/tubing that is free of breach points and interconnects to the patient access point. The inner wall allows for transmission of UV light into the fluid space. The walls define a space therebetween that is relatively small radially, allowing for a sufficient flow rate, but providing a large surface area and small fluid depth for exposure to the UV light. The UV light is provided by an elongated lamp within a cavity of the inner wall.Type: GrantFiled: March 29, 2010Date of Patent: June 10, 2014Assignee: Dartmouth-Hitchcock ClinicInventors: Corey A. Burchman, Steven D. Reinitz, Kathryn E. Boucher, Renee N. Cottle

Publication number: 20140151293Abstract: Contaminating material is extracted from a body of water by providing a floating bed on which plants such as Cat Tails can be grown with their roots hanging into the body of water over an area where extraction of contaminating material from the body of water is required, growing the plants to take up the contaminating material from the body of water and harvesting the upstanding plant mass by moving the bed to a harvesting machine which cuts away the plant mass leaving at least part of the root mass to continue growing into a new season. The bed can be returned to a location for the next season.Type: ApplicationFiled: November 26, 2013Publication date: June 5, 2014Inventor: Michael Francis Curry

Publication number: 20140144835Abstract: A system for harvesting rainwater for use in a skirt building. The skirt building includes a main building and a podium supporting the main building. The system includes: a standpipe; a buffer channel; a filter channel; and a green roof. The green roof includes a vegetation region including a baffled diversion corridor, and a bottom filtering layer including a drainage pipe. The standpipe is arranged on the main building and is connected to the buffer channel where the energy of rainwater flowing out of the standpipe is dissipated. The buffer channel, the filter channel, and the green roof are arranged on the podium, and the buffer channel communicates with the filter channel. The filter channel is connected to the green roof. The filter channel is divided into a plurality of sections respectively filled with different matrix materials.Type: ApplicationFiled: November 27, 2013Publication date: May 29, 2014Applicants: Promotion Centre of Science and Technology Development, Ministry of Housing and Urban-Rural, Chongqing UniversityInventors: Hongxiang CHAI, Feng ZHANG, Weijie WANG, Yanrong BAO, Luwei GUO, Shen LI, Hua ZHAO

Patent number: 8734646Abstract: A system for converting urine into potable water for drinking and use in a hand washing station (165) comprises a commode (100), a three-way valve (110) at the outlet of the commode, a urine reactants tank (145), a storage container (160), a pump (170), and a spigot (175). A user turns an actuator (111) on the valve in one direction to direct feces and feces-plus-urine into a reactants tank for feces, and in another direction to direct urine into the urine reactants tank. The urine reactants tank contains a plurality of baffles (210) separating the tank into chambers. A first chamber contains algae and microorganisms supplied by a seed (150). These organisms absorb nutrients from the urine as they grow into a mass (152). A last chamber contains only purified water which flows from the tank into the storage container from which it can be pumped to the spigot.Type: GrantFiled: October 11, 2013Date of Patent: May 27, 2014Inventors: Allen John Schuh, Jordan Timothy Porter, Jake Timothy Porter

Publication number: 20140138307Abstract: A scalable, modular water filtration and re-capture system is disclosed, such as for use as a high performance bioswale, or other purposes. The system includes a filter container with a removable cartridge that contains a filter media soil and planted vegetation, which may be for example one or more hyperaccumulators. The filter container is stacked together with a cistern container and in fluid communication therebetween to form a stacked container pair as a water filter and capture module. This allows for efficient servicing and removability of the filter cartridge, such as in bioswale, below ground, or above ground configurations. Water inflows and outflows may be circulated for varieties of reclamation uses, or treated water may simply be stored or conveyed into the ground. Multiple such modules may be secured together in custom scalable configurations to meet various needs and intended uses for water volumes, available space or terrain, or specific water treatment needs.Type: ApplicationFiled: September 3, 2013Publication date: May 22, 2014Inventors: Jeff Howard Coffman, Guy Stivers
