Publication number: 20180370827Abstract: A method of operating a waste water treatment plant (WWTP) having at least one of an aerobic digester (AD) and a membrane bioreactor (MBR) is described. The method of operating AD is comprised of monitoring and controlling AD in real-time using an online extended Kalman filter (EKF) having a online dynamic model of AD. The EKF uses real-time AD measured data, and online dynamic model of AD to update adapted model parameters and estimate model based inferred variables for AD, which are used for AD control by AD control system having supervisory and low-level control layers. The method of operating MBR is similar to that of AD. The supervisory control ensures the WWTP satisfying the effluent quality requirement while minimize the operation cost. A WWTP having at least one of an AD or MBR is disclosed. The method of operating a WWTP can be implemented using a computer.Type: ApplicationFiled: August 14, 2018Publication date: December 27, 2018Applicant: General Electric CompanyInventors: Aditya Kumar, Anthony John Murray, Ruijie Shi, Zhaoyang Wan, Mustafa Tekin Dokucu, Vijaysai Prasad

Patent number: 9433903Abstract: A gas sparger for a filtering membrane system produces an intermittent flow of bubbles even if provided with a relatively continuous gas flow. The sparger has a housing to collect a pocket of gas and a conduit to release some of the gas from the pocket when the pocket reaches a sufficient size. Optionally, a cover over an outlet from the conduit may break up or distribute the released gas. A large sparger for can comprise a plurality of smaller units or areas. The supply of gas to the sparger may vary in flow rate over larger periods of time in response to changes in conditions in the membrane system to change the time between consecutive bursts of bubbles. A gas supply pipe may have two or more outlets at different elevations in communication with each of two or more units or areas.Type: GrantFiled: July 30, 2010Date of Patent: September 6, 2016Assignee: ZENON TECHNOLOGY PARTNERSHIPInventors: Jeffrey Ronald Cumin, Henry Behmann, Youngseck Hong, Reid Bayly, Zhaoyang Wan, Joseph Breitner

Patent number: 8517600Abstract: A system and method are disclosed wherein differential heat transfer resistances are used to effectively and efficiently detect the early onset of deposit accumulation in industrial fluid processes and fluid transport vehicles. According to one embodiment, a probe is provided in conjunction with a heat source, a water source and a probe. The probe is comprised of a heat transfer surface, a first part of which is covered only by a thin metal layer. The second or remaining portion of the heat transfer surface is covered by a heat flux sensor and a thin metal layer. The metal layers of both the first and second areas of the probe are connected, and water flows across the full heat transfer surface. Deposition forms on a portion of the heat transfer surface as a result of slow water flow and elevated water temperature. The temperatures of the heat source, water source, and heat flux are measured. The deposition rate as a rate of change of heat transfer resistance is measured.Type: GrantFiled: October 27, 2009Date of Patent: August 27, 2013Assignee: General Electric CompanyInventors: Zhaoyang Wan, Caibin Xiao

Publication number: 20090057210Abstract: A filtration system is disclosed that uses a combination of dead end filtration across opposing membranes with a sample take-off in the middle and cross-flow to prevent cake formation on these opposing filters. In one embodiment is a system that uses opposing filters with a central collection chamber that flips flow back and forth between the sides at a frequency that minimizes filter cake formation. In another embodiment, a combination flip-flip, cross flow system is disclosed. An additional embodiment discloses an actuator valve driven sampling system, in which valves collect the cross flow/counter flow filter cake samples as they are liberated from a filter surface and a quick through filter fluid pulse loosens the sample cake from the filter material. The invention increases effective operation time, allows for continuous filtration operation without interruption, and provides filtered samples that accurately represent the concentration of macromolecular species in industrial systems.Type: ApplicationFiled: August 18, 2008Publication date: March 5, 2009Inventors: Kenneth Charles Barrett, Scott Boyette, Caibin Xiao, Zhaoyang Wan
