Publication number: 20170173558Abstract: A method, device, article of manufacture and apparatus are disclosed for binding successive layers of a “guest specie” such as an atom, cation, anion, organic molecule, and/or pathogen to a substrate or multiple different substrates. Possible substrates include materials with a porous nature; macro, micro and nano porous materials are all candidates. The adsorbent capacity of a substrate is extended by coordinating a layer of bi- or multi-functional ligand (L) to an adsorbed atom or ion or molecule or pathogen, which is then coordinate to a second layer of adsorbed atom or ion or molecule or pathogen.Type: ApplicationFiled: December 28, 2016Publication date: June 22, 2017Applicants: Crystal Clear Technologies, Inc., University of OregonInventors: Darren Johnson, Melanie Pitt, James Harris

Patent number: 9221018Abstract: Forward osmosis methods and apparatus using a supported osmotic agent to establish or enhance an osmotic forward bias are disclosed. A supported osmotic agent may be assisted by osmotic agents not attached to a support and/or a pressure differential between an influent and effluent chamber and/or a temperature gradient and/or other means to increase the osmotic pressure in an effluent chamber.Type: GrantFiled: August 8, 2008Date of Patent: December 29, 2015Assignee: Crystal Clear Technologies, Inc.Inventor: James M. Harris

Patent number: 7713496Abstract: The invention has two primary portions, a means to provide ultra-violet radiation and a means for adsorbing organic, inorganic and, optionally, pathogens. The means to provide ultra-violet radiation comprises ultra-violet light sources emitting, at least in part, in the spectrum around 265 nm. Light emitting devices, including light emitting diodes and other solid state light emitting devices are available in this range as well. The adsorbent portion comprises several different adsorbent media, including zeolites, titanium dioxide (TiO2), alumina, carbon, micro- and/or nano-porous carbon, other minerals with a naturally occurring micro- and/or nano-porous structure, synthetic, including organic, substrates with a micro- and/or nano-porous structure, and surface-modified variations of the preceding adsorbents.Type: GrantFiled: December 7, 2005Date of Patent: May 11, 2010Assignee: Crystal Clear Technologies, Inc.Inventor: James M. Harris

Patent number: 6862573Abstract: An automated knowledge dependent transaction management system for processing both the front-end and back-end of a transaction is provided. The system contains hard-coded transaction management module to support the processing of deterministic manual work independent of the specific transactions. According to the invention, the hard-coded module is separated from the business logic that comprise the definition and configuration of the transaction specific data models, business rules and process steps which drive the manual work of human operators. Such separation of code and business logic allows any ordinary business administrator without any computer programming experience to quickly develop the business logic through a simple GUI. Further, any change in the business logic can be implemented quickly using the GUI by the ordinary administrator to accommodate changes in the business environment without relying on computer programmers.Type: GrantFiled: March 22, 2001Date of Patent: March 1, 2005Assignee: Clear Technology, Inc.Inventors: John Kendall, Chris Phillips

Patent number: 5205936Abstract: A sequencing batch reactor is controlled to provide an effective, efficient treatment of raw waste water. Controls include regular withdrawal of mixed liquor during each cycle of operation. The withdrawal is volumetrically controlled to provide a sludge retention time of 5 to 10 days in the system. This produces a carbon and nitrogen oxydizing bacterial culture with good setting properties. Hydraulic loads in the system are controlled according to liquid levels, while the bacterial processes are controlled by timed sequences. A storm control procedure monitors the influent rate and shortens the cycle times according to the magnitude rate, to increase the system capacity. The system also includes a novel effluent withdrawal system, with a check valve controlled intake about midway up the reactor. This is trouble-free, with the check valve preventing sludge entry into the effluent withdrawal and maintaining prime on the effluent withdrawal pump.Type: GrantFiled: February 5, 1992Date of Patent: April 27, 1993Assignee: Bio Clear Technology Inc.Inventor: Brian H.
