Patent number: 11514208Abstract: Aspects described herein provide a computer implemented radio frequency propagation simulation tool to allow the simulation of radio frequency propagation across a topographic area which has been very finely mapped in three dimensions to include possible obstructions to high frequency radio waves. A computer implemented RF propagation simulation tool may identify any possible obstructions one edge of which may lie in a simulated RF propagation path between two points, and apply an edge based RF diffraction model (a so-called “knife edge diffraction” model) thereto to simulate the RF propagation around the obstruction. In some aspects, a computer implemented RF propagation simulation tool may identify possible obstructions which in their entirety lie within the width of a simulated RF propagation path, and apply a further diffraction model (a so-called “shield diffraction” model) thereto to simulate the RF propagation around the obstruction.Type: GrantFiled: September 28, 2018Date of Patent: November 29, 2022Assignee: Ordnance Survey LimitedInventors: Jack Harrison, Richard Woodling, Bart Chudas

Patent number: 8815096Abstract: An integrated process for removing sulfate from water sources, such as pretreated acid mine drainage (AMD). The multivalent cation (MVC) content of a sulfate stream is reduced by strong acid cation (SAC) ion exchange and sulfate is concentrated with a membrane system and separated as precipitate and overflow. Precipitation results from reaction of sulfate with MVC produced by regeneration of SAC with sodium chloride. The overflow is reacted with carbonate to precipitate MVC, generate sodium chloride and give a further overflow stream. This latter stream is concentrated to a level capable of being a regenerant for the SAC and when needed, used to regenerate the SAC and produce MVC for sulfate precipitation. The process minimizes the use of chemicals by treating, reconcentrating and recycling input species. Capital expenditures are minimized by precipitation of only side streams.Type: GrantFiled: April 13, 2009Date of Patent: August 26, 2014Assignee: Siemens AktiengesellschaftInventors: Joseph Edward Zuback, Richard Woodling

Patent number: 8758632Abstract: Aspects and embodiments of the present invention are directed to apparatus and methods of filtering a fluid to reduce a level of at least one contaminant therein. The filtering of the fluid may be accomplished with a radial flow filtration column comprising a fluid chamber having an inlet, an outlet, and a side wall, an inner permeable retainer positioned in the fluid chamber, an outer permeable retainer positioned in the fluid chamber spaced apart from and surrounding the inner permeable retainer, a media bed compartment formed between the inner permeable retainer and the outer permeable retainer, and an adjustable element biased into the media bed compartment and configured to maintain a predetermined packing density of a media bed to be disposed within the media bed compartment.Type: GrantFiled: March 24, 2011Date of Patent: June 24, 2014Assignee: Evoqua Water Technologies LLCInventors: Davis Yohanes Arifin, Kok Wee Henry Lim, Karthikeyan Sathrugnan, Richard Woodling

Publication number: 20110318237Abstract: Ultraviolet reactors having an ultraviolet light source for treating a fluid are disclosed. In one embodiment, a reactor is disclosed which includes a vessel having an inlet for receiving fluid and an outlet for discharging fluid. The vessel further includes a plurality of segmented baffles. The baffles further include a partial circumferential edge section that terminates in a vertical edge section to form right and left segmented baffles. The left and right segmented baffles are arranged in an alternating pattern in the vessel to provide plug flow and enhanced radial mixing.Type: ApplicationFiled: June 26, 2010Publication date: December 29, 2011Inventors: Richard Woodling, Jing Feng, Davis Yohanes Arifin, Kok Wee Henry Lim

Publication number: 20110163032Abstract: A high recovery sulfate removal process comprises treating a feed water stream conditioned with antiscalant from a source with a reverse osmosis membrane system to produce a purified water permeate stream and a reject stream containing the retained or rejected ions and organic matter. The reject stream is further treated to remove dissolved and suspended species. The reject stream flows to a desaturation/clarification process. A preferred process includes a constant stirred tank reactor (CSTR) where co-precipitation agent is added followed by a clarifier. Water recycled from the clarifier overflow is blended with feed water stream. The removed solids are collected as sludge or a slurry and disposed of in a manner consistent with applicable regulations.Type: ApplicationFiled: September 17, 2009Publication date: July 7, 2011Applicant: Siemens Pte LtdInventors: Gerald Alexander, Stanley R Karrs, Richard Woodling, Karthikeyan Sathrugnan

Patent number: 5597489Abstract: Contaminants in ground water, waste water and industrial effluents are removed using a contaminant removing media packed in a radial flow column. The radial flow column includes a fluid chamber having cylindrical inner and outer screens positioned therein. A contaminant removing media is packed in a media bed between the inner and outer screens. Contaminated water is passed through the column with the water passing through the outer screen, the contaminant removing media and out the inner screen.
