Patent number: 10017406Abstract: An upflow continuous backwash deep bed sand filter (UCBF) having a recycle line for returning carbonaceous denitrifying bacteria attached to biomass to the influent of the UCBF. The recycle line returns the biomass to the treatment process at a location upstream of the upflow continuous backwash filter. Further, a liquid level control unit is provided that reduces fluctuations and significant drop in the liquid level upstream of the upflow continuous backwash filter, thereby avoiding or minimizing flow turbulences, air induction, and undesirable wastewater aeration resulting in the need to dose excessive carbon source to remove dissolved oxygen in the aerated wastewater.Type: GrantFiled: October 2, 2013Date of Patent: July 10, 2018Inventors: John H. Reid, Wade Tanner

Patent number: 10000397Abstract: Described herein are attached growth reactor systems which increase nitrifying bacteria biomass through a variety of means during warm weather. As a consequence, the attached growth reactor system contains sufficient nitrifying bacteria biomass to remove ammonia from wastewater in cold to moderate climates. In one example, there are two attached growth reactors into which wastewater is distributed discontinuously. Specifically, wastewater is transferred to the first attached growth reactor for a first period of time and then is transferred to the second attached growth reactor for a second period of time during warm weather which effectively doubles the nitrifying bacteria biomass in the system. During cold weather, approximately half of the wastewater is applied to each reactor simultaneously.Type: GrantFiled: August 23, 2017Date of Patent: June 19, 2018Inventors: Martin Hildebrand, Merle Kroeker

Patent number: 9902636Abstract: A method for reducing recalcitrant chemical oxygen demand (COD) of a liquid in a water system is provided. The method comprises pretreating the liquid in a pretreatment unit (12) to remove indigenous bacteria or microbes to a population level below which the indigenous organisms can interfere with the screened and externally introduced microorganisms. The liquid is then provided to a reactor (20) that has a filter bed (22) formed with a carrier material (26). Special microbes are screened and used to colonize the carrier material (26) to remove recalcitrant COD. A biofilm is cultured on the surface of the carrier material (26) to immobilize the screened microbes in the reactor (20). The method further comprises adding a co-substrate as the liquid enters the reactor (20) and percolating the liquid through the filter bed (22) colonized with the screened microbes to degrade at least part of the recalcitrant COD under aerobic conditions.Type: GrantFiled: September 10, 2012Date of Patent: February 27, 2018Assignee: General Electric CompanyInventors: Sijing Wang, Lei Wang, Haiwu Zhang, Weiqing Xu, Ying Zhou

Patent number: 9751786Abstract: The invention relates to a fixed bed for aerobic or anaerobic wastewater purification, comprising an upper frame having support elements fixed to opposite side rails and/or intermediate rails for attaching textile, foldable, non-degradable supports for microorganism, a lower frame having support elements for fixing the textile supports to the lower frame, and means connecting the frames at a corner region. The invention is a fixed bed where all parts of the fixed bed can be assembled to form a relatively small packaging unit that already contains the inserted textiles. Frames are provided with spacers at least in the corner regions, the height of which spacers corresponds to the material height of the folded supports between two frames and the supports are fixed by means of the supports members to the side rails and/or intermediate rails of the frames in a preassembly step before folding.Type: GrantFiled: September 10, 2012Date of Patent: September 5, 2017Assignee: B+M TEXTIL GMBH & CO.

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: 9138695Abstract: An apparatus for making high-oxygenated water includes an oxygen supply, an exchange tank, and a pressure tank. The oxygen supply respectively supplies pure oxygen to the exchange tank and the pressure tank. The pure oxygen is dissolved in water in the exchange tank in a normal pressure environment to obtain oxygenated water. A slow-down unit is provided in the exchange tank to extend the time of the pure oxygen staying in the exchange to raise the dissolved oxygen of the oxygenated water. Next, the oxygenated water is drained to the pressure tank, and then the pure oxygen is dissolved in the oxygenated water in the exchange tank in a high pressure environment to obtain high-oxygenated water.Type: GrantFiled: November 9, 2012Date of Patent: September 22, 2015Inventor: Chien-An Chen
