Publication number: 20100040421Abstract: An apparatus for pneumatically conveying particulate material from a container to an application site includes a mill that is operative to reduce the particle size of the material. The apparatus further includes a blower. Pneumatic lines are configured to connect the blower pneumatically with the application site through the container to convey material-laden air from the container to the application site. The pneumatic lines are configured for connection in alternative milling and non-milling arrangements.Type: ApplicationFiled: October 6, 2009Publication date: February 18, 2010Applicant: O'BRIEN & GERE ENGINEERS, INC.Inventors: Eric T. Fleckten, David M. Gerber, Stephen C. Palin

Publication number: 20090194618Abstract: The present invention provides an in-line system for milling sorbent material to be used in a pneumatic conveying system. The system provides for optimal particle size in a duct injection system, regardless of the original sorbent particle size, and is designed to prevent clogging of the milled material through the system. Methods of operation for milling, as well as cleaning the mills while providing various sorbent material by-pass configurations to minimize system down-time while enhancing material throughput and that support the unique aspects of the system, are also described in detail below.Type: ApplicationFiled: January 26, 2009Publication date: August 6, 2009Applicant: O'BRIEN & GERE ENGINEERS, INC.Inventors: Stephen C. Palin, Jonathan Norman, Eric Fleckten

Publication number: 20060075899Abstract: An apparatus is disclosed, for filtering, containing and removing mold spores and other undesirable particulates in conjunction with a conventional vacuum cleaner. The apparatus includes a cylindrical housing that contains a HEPA filter. The cylindrical housing is connected to an exhaust tubular connection which connects to a conventional vacuum or other vacuum source. The cylindrical housing is also connected to an intake tubular connection for drawing in a stream of air from which particles will be filtered. The cylindrical housing also includes a valve for selectively sealing the interior of the cylindrical housing from the atmosphere. According to one embodiment, the apparatus also includes a pressure relief valve for controlling the vacuum pressure. According to another embodiment, the apparatus includes a clamp for securing the apparatus to hoses of various sizes.Type: ApplicationFiled: October 4, 2005Publication date: April 13, 2006Applicant: O'Brien & Gere Engineers, Inc.Inventor: James Evans

Patent number: 6592757Abstract: The apparatus of the present invention generally comprises a wastewater contact tank that is broken into three distinct zones: a selector zone positioned between a stabilization zone and a contact zone. The entire influent is introduced into the selector zone which is maintained in an anoxic condition. Baffles positioned within the selector zone permit control of microorganisms levels present in the zone. The wastewater introduced into the selector zone and treated via the microorganisms present therein, flows over a weir into the contact zone. In the contact zone, the solids suspended in the liquor (the mixture of the wastewater and activated sludge) settle to the bottom and pass through a line which returns it to the selector zone. The return line, however, includes a valve which controls the rate of passage. The treated wastewater (which includes waste activated sludge and treated water) passes from the contact zone into the clarifiers for final processing.Type: GrantFiled: January 30, 2001Date of Patent: July 15, 2003Assignee: O'Brien & Gere Engineers, Inc.Inventor: Sami M.

Patent number: 6565750Abstract: The present invention provides a two stage process for treating wastewater that subjects the influent to anoxic and oxic filtering processes. The first stage performs anoxic nitrification i.e., the conversion of nitrate to nitrogen gas by bacteria operating in the absence of oxygen. Influent (effluent from the primary clarifiers) is fed into the bottom of the anoxic dentirification tank, preventing contact with the atmosphere and thus reducing the amount of unwanted dissolved oxygen. The influent passes upwards through a layer of sludge biomass before contacting bacteria coated media which performs the denitrification process. This arrangement permits the influent to contact the sludge and the biomass to circulate through the filter, enhancing deoxygenation and the performance of the system.Type: GrantFiled: August 31, 2001Date of Patent: May 20, 2003Assignee: O'Brien & Gere Engineers, Inc.Inventor: Sami M.
