Publication number: 20240091708Abstract: Wastewater is treated though primary treatment of the water by way of a micro-sieve to produce a primary effluent and primary sludge. There is secondary treatment of the primary effluent by way of a membrane bioreactor (MBR) or an integrated fixed film activated sludge (IFAS) reactor to produce a secondary effluent and a waste activated sludge. The micro-sieve may have openings of 250 microns or less, for example about 150 microns. In a process, a gas transfer membrane is immersed in water. Pressurized air flows into the gas transfer membrane. An exhaust gas is withdrawn from the gas transfer membrane and used to produce bubbles from an aerator immersed in the water.Type: ApplicationFiled: November 14, 2023Publication date: March 21, 2024Inventors: Pierre Lucien COTE, Steven Kristian PEDERSEN, Wajahat Hussain SYED, Jeffrey Gerard PEETERS, Nicholas William H.

Patent number: 11453010Abstract: In an apparatus and process described, an organic fraction of solid waste is separated from light contaminants such as plastics and heavy contaminants such as grit. The organic fraction is subsequently processed by anaerobic digestion, which converts volatile solids to gas. In a first stage of the process, the waste is processed through a separator such as a vertical mill, which removes light fraction contamination, reduces organics particle size and dilutes the waste to thereby produce a slurry. In a second stage of the process, the slurry passes through a grit removal system, which removes heavy and settleable material, for example by way of a hydrocyclone. The light and heavy fraction contaminants are not carried through to the digestion process. The particle size of the organics is also reduced to facilitate digestion and the slurry has a dry solids concentration suitable for anaerobic digestion.Type: GrantFiled: October 11, 2018Date of Patent: September 27, 2022Assignee: BL TECHNOLOGIES, INC.Inventors: Michael Theodoulou, Youngseck Hong, Nick Braithwaite, Marion De Backer

Patent number: 9556046Abstract: A membrane supported biofilm apparatus has a plurality of hollow fiber gas permeable membranes in a tank containing water to be treated. A biofilm supported on the membranes occupies between about 40% and 80% of the volume of water to be treated in a reactor. Wastewater treatment processes are described. A process to denitrify water or treat oxidized contaminants comprises introducing hydrogen into an inner volume of the membranes to grow autotrophic organisms in the biofilm near the membrane and heterotrophic organism near the water. Another process is operated as a biomass concentration of at least 10 g/L and up to about 40 g/L to maintain a biofilm having a surface area of over 1000 square meters per cubic meter of tank volume. A hybrid process has suspended biomass and a membrane supported biofilm.Type: GrantFiled: February 27, 2015Date of Patent: January 31, 2017Assignee: ZENON TECHNOLOGY PARTNERSHIPInventors: Hidayat Husain, Rocco Mazzaferro, Minggang Liu, Richard Wong, Heather Lossing, Fengshen Fan, Youngseck Hong, Reid Bayly

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: 8580113Abstract: In an anaerobic membrane bioreactor (“MBR”), a closed anaerobic process tank contains a membrane filter or is connected to an external tank containing a membrane filter. A pocket of biogas accumulates at the top of the process tank. Biogas is taken from the pocket, pumped to the bottom of the membrane filter to provide bubbles to inhibit membrane fouling, and returned to the pocket. Excess biogas produced as the wastewater is degraded is removed from the system and may be used as a product. However, biogas and liquid are maintained in the system at a pressure above atmospheric, for example 10 kPa or more above atmospheric pressure, sufficient to provide at least a material contribution to the transmembrane pressure driving permeation through the membranes. The overall energy requirements of the system may be reduced. Further, with sufficient pressure, suction pumps attached to the membranes may not be required.Type: GrantFiled: August 31, 2010Date of Patent: November 12, 2013Assignee: Zenon Technology PartnershipInventors: Youngseck Hong, Reid Allyn Bayly, Domenico Salasso, Jeffrey Ronald Cumin, David Eaton Sproule, Sheng Chang

Patent number: 8528745Abstract: A membrane supported biofilm apparatus has a plurality of hollow fiber gas permeable membranes in a tank containing water to be treated. The membranes have an outside diameter of about 200 microns or less and occupy between 0.5% and 4% of the tank volume. A biofilm supported on the membranes occupies between about 40% and 80% of the volume of water to be treated in a reactor. The membranes may be oriented generally vertically and a spreader may be located near the bottom of the apparatus to disperse the membranes. Wastewater treatment processes are described. A process to dentrify water or treat oxidized contaminants comprises introducing hydrogen into an inner volume of the membranes to grow autotrophic organisms in the biofilm near the membrane and heterotrophic organism near the water. Another process is operated at a biomass concentration of at least 10 g/L and up to about 40 g/L to maintain a biofilm having a surface area of over 1000 square metres per cubic metre of tank volume.Type: GrantFiled: April 14, 2008Date of Patent: September 10, 2013Assignee: General Electric CompanyInventors: Hidayat Husain, Rocco Mazzaferro, Minggang Liu, Richard Wong, Heather Lossing, Fengshen Fan, Youngseck Hong, Reid Bayly
