Publication number: 20120267325Abstract: The invention relates to a wastewater treatment plant and method for treating wastewater, and to a wastewater treatment system having a plurality of filter layers disposed one under the other for purifying the wastewater, wherein at least one feeding device (200) for feeding wastewater to the filter layer (110) and at least one discharge device (300) for discharging the purified wastewater from the filter layer (110) is associated with each filter layer (110). The feeding device (200) for at least two of the filter layers (110) is directly fluidically connected to a wastewater feeding line (400) and the discharge device (300) is directly fluidically connected to an intermediate store (600), such that the unfiltered quantity of wastewater fed to each filter layer (110) can be filtered by said filter layer (110).Type: ApplicationFiled: July 23, 2010Publication date: October 25, 2012Inventors: Tariq Kaddoura, Gert Köhler

Patent number: 8252148Abstract: A mobile waste processing system and method is disclosed for processing materials in a tank, typically an underground storage tank. A mobile fluid processing module is disposed adjacent to or over the tank, and sealingly connected to the tank through a tank riser. Support equipment, which may include an electric power module, a chiller module, a heating module, and a control and monitor module, are disposed a distance from the processing module, and connected thereto. A pump and optionally a dispersal nozzle are deployed from the processing module into the tank, and effluent is extracted for processing. The processing trailer includes effluent processing equipment such as an evaporator and demister, condenser, vacuum pump, and interim storage tank. The effluent is processed, and at least a portion is removed. Some of the processed effluent may be returned to the tank.Type: GrantFiled: June 15, 2011Date of Patent: August 28, 2012Assignee: Columbia Energy & Environmental Services, Inc.Inventors: Stephen Wolfe, Brian Brendel

Patent number: 8246791Abstract: A method and apparatus for separating draw solution solutes and product solvent from a draw solution using a plurality of distillation columns is disclosed. In one embodiment, the draw solution is used in a Forward Osmosis (FO) water desalination process. In this embodiment, the draw solution is directed to the plurality of distillation columns in parallel while the energy stream (heat) is directed to the plurality of distillation columns in series such that the efficiency of heat use is improved and in turn the cost of the heat is reduced.Type: GrantFiled: June 7, 2007Date of Patent: August 21, 2012Assignee: Yale UniversityInventors: Robert L. McGinnis, Menachem Elimelech

Patent number: 8231793Abstract: A cartridge type filter is mounted in a housing and is serviced through the top of the housing. The cartridge includes first and second media packs axially stacked. The second media pack is in series behind the first media pack, and filters a portion of the liquid therethrough. The second media pack has a higher efficiency than the first media pack. The overall design has a drain system which allows liquid to drain from the interior of the filter housing and back to the sump before the filter cartridge is completely removed from the housing. Other optional features include an oil cooler, various valving, and a filter cartridge lockout mechanism.Type: GrantFiled: January 22, 2009Date of Patent: July 31, 2012Assignee: Donaldson Company, Inc.Inventors: John R. Hacker, Bradley S. Honermann, Mark S. Emery

Patent number: 8226832Abstract: A method that can be used in a portable system and apparatus to effectively and efficiently treat aqueous fluids by quickly and reliably adjusting and controlling the free residual level of disinfectants, contaminants or additives through the addition of one or more treating agents such as oxidizing chemicals and/or other special-purpose additives, and that can continuously store, log, retrieve and report the related fluid composition data and other operating parameters on a real-time basis at either the use site or a remote location. A preferred use for the subject method is managing the chemistry of disinfectant, contaminant and/or additive levels in aqueous fluids used in hydraulic fracturing operations, and controlling the free residual levels of the disinfectant or contaminants within the fluids, including fluids maintained in frac tanks during temporary cessation of a hydraulic fracturing operation.Type: GrantFiled: April 9, 2010Date of Patent: July 24, 2012Assignee: NCH Ecoservices, LLCInventors: Jerome F. Angelilli, Patrick D. Guccione, Billy E. Pierce, Daniel Wai-tak Wong, John H. Williams
