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 An exhaust gas is withdrawn from the gas transfer membrane and used to produce bubbles from an aerator immersed in the water.Type: ApplicationFiled: November 14, 2023Publication date: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.

Publication number: 20240084503Abstract: The present disclosure is directed to use of a composition for restoring of a cellulose-containing used garment in a non-industrial laundry equipment selected from a domestic laundry equipment and a professional non-industrial equipment, wherein the composition comprises from about 15% to about 60% of a cellulase preparation, wherein the restoring is selected from a group consisting of: (i) restoring of a mechanical tension of the garment, thereby achieving a re-shaping of the garment, (ii) de-pilling of a surface of the garment, and (iii) de-fraying of a collar(s) and/or edge(s) of the garment, and any combinations thereof. Also disclosed are compositions for use in restoration of a cellulose-containing used garment and methods for restoring a cellulose-containing used garment in a non-industrial laundry equipment selected from a domestic laundry equipment and a professional non-industrial equipment.Type: ApplicationFiled: January 14, 2022Publication date: March 14, 2024Inventor: Wajahat HUSSAIN

Patent number: 11661366Abstract: Water containing selenium, for example flue gas desulfurization (FGD) blowdown water is treated with a combination of biological and chemical treatment and membrane filtration. The biologically treated water is dosed with a dithiocarbamate compound and flocculated prior to membrane filtration. Optionally, the treatment may be enhanced with one or more adsorptive agents prior to, or in conjunction with, membrane filtration. Membrane concentrate may be re-circulated to one or more biological treatment zones. The biological treatment may be by way of suspended growth, fixed growth on a moving bed, or both. One or more biological treatment zones may be controlled considering their oxygen reduction potential (ORP). Optionally, the biological treatment includes an aerobic zone following one or more anoxic or anaerobic zones. The non-aerobic zones remove selenium and optionally nitrogen and sulfur. The aerobic zone removes carbon, which may include carbon added as a nutrient in a non-aerobic zone.Type: GrantFiled: June 30, 2016Date of Patent: May 30, 2023Inventor: Wajahat Hussain Syed

Patent number: 10486992Abstract: A membrane bioreactor (MBR) has membranes comprising a supporting structure. A supply unit doses a sorbent such as powdered activated carbon (PAC) into the MBR. The PAC is maintained at a concentration in the mixed liquor of 200 mg/L or more. Mixed liquor with the sorbent particles recirculates within the MBR at a flow rate of at least twice the feed flow rate. Air bubbles are provided to scour the membranes including during at least part of a permeation step. The sorbent particles are present in the mixed liquor and contact the membranes. Bioaugmentation products may be immobilized on PAC or other carriers and then added to an MBR or other bioreactors.Type: GrantFiled: December 7, 2012Date of Patent: November 26, 2019Assignee: BL TECHNOLOGIES, INC.Inventors: Sijing Wang, Nicholas William H.

Publication number: 20170072345Abstract: This specification describes methods and apparatus for cleaning a micro-sieve medium such as a belt in a rotating belt sieve. In one method, water is mixed with air supplied to an air knife blowing against a micro-sieve medium. The water may provide droplets of water in air contacting the micro-sieve medium although the volumetric flow rate is still primarily produced by a gas flow. In another method, a cleaning agent is supplied to a micro-sieve medium while the micro-sieve medium is installed in a filtration unit, and preferably while the micro-sieve medium is in use filtering water. The cleaning chemical may be applied through a liquid sprayer, but is preferably applied through an air knife. In another method, a cleaning agent is supplied to a micro-sieve medium while the micro-sieve medium is not in use, and preferably while it is removed for soaking in a separate tank.Type: ApplicationFiled: March 20, 2014Publication date: March 16, 2017Inventors: Wajahat Hussain SYED, James John ROYSTON

Publication number: 20140197829Abstract: The invention relates to a mobile carrier system for at least one sensor element for testing test objects having convex surfaces. The system is provided for testing test objects that are at least made of ferromagnetic material. For this purpose, two first rollers are attached to a frame, the rotational axes of which are oriented parallel to each other and at a distance from each other. The distance of the two first rollers can be varied, and one of the two first rollers is attached to a carriage, which can be moved perpendicularly to the rotational axes of the two first. rollers. A drive for raising and lowering the first rollers is present on the two first rollers. Two pairs of second rollers are attached to the frame between the two first rollers. At least one pair of the second rollers comprises a rotary drive.Type: ApplicationFiled: January 9, 2014Publication date: July 17, 2014Applicant: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventors: Klaus SZIELASKO, Jochen Horst KURZ, Wajahat HUSSAIN
